1. Field of the Invention
The present invention relates to an image and information processor, and more specifically to an image and information processor for images and information for medical treatment purposes, which is a standalone (i.e., independent) device or which is used by being connected to a network.
2. Description of the Related Art
Currently, a radiation image information recording and reproducing system is being used which utilizes a stimulable phosphor, and according to this system, when an irradiation of radiation (i.e., X-rays, α-rays, β-rays, γ-rays, electronic beams, ultra-violet rays or the like) is received, a portion of the radiation energy of this irradiation is stored, and then when an irradiation of laser light or visible light or other such excitation light is received, the stimulable phosphor shows a photostimulated luminescence as a result of the stored energy.
Examples of this type of radiation image information recording and reproducing system include, for example, systems such as those proposed in JP 63-253348 A, JP 01-227139 A, JP 04-123173 A and JP 04-155581 A by the present Assignee. In such a system, an image of a patient is captured at a hospital, for example, by means of an X-ray image capturing device or the like, radiation image information pertaining to this patient, for example, is stored and recorded on a sheet of a stimulable phosphor, and this sheet is scanned by means of a laser or other such excitation light to generate photostimulated luminescence light; and the system is provided with a radiation image reading device for photoelectronically reading the photostimulated luminescence light which has been obtained in this way and thereby obtaining image data; an identification information registration device for registering the patient's identification information; and an image recording device for recording a radiation image onto a photographic photo-sensitive material or other such recording material, for example, as a visible image based on the obtained image data, in connection with the registered patient's identification information and the like.
In this type of conventional radiation image information processing system, before the image of the patient is captured or at the time when the image is captured, identification (i.e., ID) information is registered in the identification information registration device (i.e., ID terminal) which is positioned proximate to the radiation image capturing device and the like; this identification information being comprised of the patient's first and last name, sex, date of birth, identification (i.e., ID) number and other such information pertaining to the patient, along with the year, month and date on which the image was captured, the region that was captured, the method by which the image was captured, a bar code information from the stimulable phosphor sheet onto which the image was captured, and other such information relating to the capturing of the image.
On the other hand, information such as the following is sent from the ID terminal to the radiation image reading device: the registered identification information and conditions for the processing of the radiation image which has been read by the radiation image reading device; an output destination for the processed radiation image (i.e., a destination to which the image data is to be distributed), meaning information regarding which image recording device the image data should be outputted to; the output conditions for outputting the processed radiation image from the image recording device; and also a distribution destination for the outputted radiation image, such as an internist's office or surgeon's office or other such particular medical specialist's office in a hospital, for example.
Also, the radiation image reading device reads the bar code on the back surface of the stimulable phosphor sheet and establishes a correspondence (relationship) with the patient's ID information which has been obtained from the ID terminal, and also reads from the stimulable phosphor sheet the radiation image information which was captured onto this stimulable phosphor sheet, performs the image processing and the like in accordance with the conditions which have been received and sends to the image recording device the processed radiation image which has thus been produced, outputting this image together with the output conditions. At the image recording device, the processed radiation image is outputted, according to the obtained output conditions, as a transparent film image equivalent to an X-ray image or reflective paper image or other such hard copy image. The outputted radiation image is distributed by means of a well known means to the distribution destination which was obtained from the ID terminal.
In the conventional radiation image information processing system disclosed in the above-mentioned publications, the radiation image reading device can read vast amounts of the stimulable phosphor sheet, and due to reduced costs, it is possible to use a plurality of radiation image reading devices; accordingly, not only is it possible to connect one of or a plurality of the radiation image reading devices to a plurality of ID terminals and position the ID terminals close to the radiation image capturing device, but also it is possible to place the ID terminals close to the reception desk or other part of the hospital or the various specialists' offices, for example, thereby improving the ease and efficiency of the inputting of the patient information and the cross-checking of the patient information against the stimulable phosphor sheet at the capturing device. Alternatively, it becomes possible to perform the reading of the stimulable phosphor sheet by any radiation image reading device, regardless of which ID terminal the stimulable phosphor sheet was registered in, thus enabling the efficient running of a plurality of radiation image reading devices
Further, in the conventional radiation image information processing system disclosed in the above-mentioned publications, it is possible to connect a plurality of ID terminals, which are connected to one or more radiation image reading devices, or a plurality of ID terminals which are each individually connected to one of a plurality of radiation image reading devices to a single managing device (such as a host computer or manager ID terminal), or connect a plurality of radiation image reading devices to a single ID information input storage unit, and thus realize integrated management of the ID information, and also it becomes possible to perform integrated management of the running status of the radiation image reading device and the image recording device, and the usage status of the stimulable phosphor sheet, and thus manage the efficient running of the radiation image reading device and the efficient use and longevity of the stimulable phosphor sheet and the like. At this time, one or more image recording device may be connected to the one or more radiation image reading devices, and thus the efficient running of the image recording device is enabled.
However, in recent years, even in this type of conventional radiation image information processing system, what is used for the image output device, which outputs the radiation image as a visible image, is not only an image recording device for recording onto the recording material, but also an image display device for performing a monitor-type display on an LCD, CRT or the like for review of the radiation image. Also, this type of image display device is now physically set up as in image review device in each specialists' office in the hospital or such, and is also set up for each physician, image inspection engineer or other type person who is to inspect the image.
Therefore, not only is the outputted hard copy image distributed to the particular specialist's office in the hospital or other such distribution destination, but also, in order to make the diagnosis more efficient, to shorten the amount of time that the patient has to wait and to speed up the medical care, the radiation image which has been read by the radiation image reading device and has been subjected to the image processing and the like is now also sent as image data for review (i.e., display) purposes to such distribution destinations as the image review devices and the like which are set up at each specialist's office or set up for each person who is to inspect the image.
In the conventional radiation image information processing system described above, the image is handled ultimately in per-image units, and it must be recognized that in recent years this has become an inconvenience since a single inspection has now come to involve several images or more.
The present invention is to be developed in light of this development whereby several images or more are used in a single inspection, and an object of the present invention is to provide an image and information processor in which the images are not handled in per-image units, but are handled in units of the several or more images to be used in the single inspection.
In order to attain the object described above, the present invention provides an image and information processor comprising: an image information processing unit having a function for inputting patient information and radiation image capture information related to the patient information; a function for receiving at least one first radiation image having been read by means of a radiation image reading device; and a function for performing image processing on the at least one first radiation image having been received from the radiation image reading device; an image display device which is connected to the image information processing unit and displays at least one of the at least one first radiation image and at least one second radiation image having been subjected to the image processing by the image information processing unit; and an external storage device which is connected to the image information processing unit and stores temporarily at least one of the at least one first radiation image and the at least one second radiation image in relation to the patient information; wherein the image information processing unit is constructed such that a serial radiography based on a plurality of radiographic conditions of the image capture information relating to one patient inputted by means of the input function can be reserved as a single inspectionire.,i.e., thermal head) which is modulated in accordance with the image data signals of the radiation image, or by means of a heat mode laser which is modulated in a similar fashion.
Note the above-mentioned photo-sensitive material and heat-sensitive material is not particularly limited, either, but it is preferable to use photo-sensitive film and heat-sensitive film, and examples of the material include silver salt photographic photo-sensitive materials, photo-sensitive heat development materials, various heat-sensitive materials or other such materials which can be used in wet exposure processing and dry exposure processing.
Also, for the image output device of the present invention it is also possible to use such well known image recording devices as an electrophotographic image recording device for transferring an image to image-receiving materials by using photo-sensitive bodies and toner, or an image recording device which uses a format whereby the image is transferred to image-receiving materials by means of a sublimation (ablation) process.
The WS 30 is an output device for using the image data signal of the processed radiation image which has been subjected to the image processing and which was received from the image information processing unit 16 through the network 34, using this image data signal to display the radiation image, which is to be used for the medical diagnosis, displaying this signal on a display screen as a soft copy image in a way such that the signal is either displayed linked to the patient's ID information, or displayed together with a part of this ID information. In the depicted example, the plural numbers of WSs 30 are connected to the image information processing unit 16 through the network 34; however, the present invention is not limited to this configuration, and it is sufficient to have one or more WS 30 units connected. Here, it is also possible to configure the WS 30 so that it receives the image data signal of the unprocessed radiation image which has not yet been subjected to the image processing and which was read by means of the radiation image reading device 24, receiving this signal from the image information processing unit 16 through the network 34, and then displays the signal on the display screen.
The display device of the WS 30 used in the present embodiment is not particularly restricted as long as it can perform display of images for medical diagnosis, and so a CRT display device (i.e., monitor), LCD (monitor) plasma display, electroluminescence panel or other such well known display or monitor may be used. This display device is used for the display of the medical diagnosis, so in order to widen the dynamic range of richness of the display, it is desirable for the brightness to be great, for the display to be capable of high resolution, and for the angle of the breadth of the field of view of the display device to be wide so that more than one doctor or inspection engineer or other such people inspecting the images can view the images simultaneously. In particular, in the case where an LCD is to be used it is desirable to use a display device which is equipped with a mechanism for expanding the breadth of the field of view of the display device.
The image saving device 28 is one type for image output device for storing and saving on a long term basis as an radiation image database at least one of the image data signal of the processed radiation image which has already been subjected to image processing and which was received from the image information processing unit 16 through the network 34 and the image data signal of the unprocessed radiation image before it is subjected to the image processing in relation to the patient's ID information. Here, the image saving device 28 functions as a database of radiation images, so it is desirable to provide this as one type of image output device for the present system; however, if there is no need to provide a database for radiation images, then it is not necessary to provide these. The capacity of the image saving device 28 (i.e., the database capacity) is not particularly restricted, and it is sufficient to select the capacity appropriately in light of the scale of the processing system.
Further, the radiation image data can be stored into the image saving device 28 at any time; however, if the image saving device is also to be given a function of performing backups, then it is good to store the radiation image data at the time when they are temporarily stored to the external storage device 18, but due to circumstances regarding the storage capacity of the image saving device 28, it may be good to save the radiation image data at the time when they are deleted from the external storage device 18. Note that there is no particular limitations on the types of radiation image which are to be stored in the image saving device 28 as the database, and so it is possible to save all the images which are to be saved in the external storage device 18; however, it is also possible to select a portion therefrom to save. The selection of the radiation image which is to be saved into the image saving device 28 can be made at the time when the temporarily saved radiation image is deleted from the external storage device 18.
The IDT 32 is a terminal which is equipped with a keyboard and mouse for inputting, and a monitor, and it is to be used for doing such things as inputting and confirming the patient information, the image capturing information and other such patient ID information, and it can be used, instead of the image information processing unit 16 of the IIP 10A, which is inside the system according to the present embodiment, for doing such things as inputting the patient's ID information, or inputting a portion of the patient's ID information which has not been inputted by means of the image information processing unit 16, then sending this information through the network 34 to the image information processing unit 16 to register it and storing it into the external storage device 18, or using a portion of the patient's ID information which is registered in the image information processing unit 16 to search the external storage device 18 which is connected to the image information processing unit 16, and then cross-checking and confirming a portion of or all of the ID information, or obtaining a portion of or all of the patient's ID information from a magnetic card which has been issued to the patient, and performing searching, cross-checking, confirmation, and the like.
It is also possible to make a reservation for an inspection from the IDT 32. A reservation for an inspection is typically performed by the doctor from one of the WS 30 units in each of the specialist's offices; however, when a prescription for an inspection has been given, for example, there could be cases in which an operator in another department actually performs the input. As described above, in recent years there are many cases in which the inspection generally includes more than one image taken for a given patient, so it is efficient to adopt a method in which the content of the inspection is reserved by means of an input from the IDT 32, and then an engineer from the department specializing in the taking of the images reads out the content of the inspection and makes a reservation for a specific kind of image-taking session. Note that in the actual operations it is good to prepare a screen, such as is described below, which is only used for the purpose of making inspection reservations, and then make selections from this screen in sequence to determine the content of the inspection from selections appearing on the screen, and then input necessary itemized information.
In the case where the invention is to be used frequently in the way described above, it is desirable to arrange the IDT 32 at each of the devices other than the IIP, which means it is arranged at the radiation image capturing device 26, the reception desk in the hospital, the reception desks at each of the specialists' offices, etc., and to thereby facilitate to conduct the input operations and the making of the reservation for the inspection. Additionally, the IDT 32 can be arranged at the radiation image reading device 24, the image output device 22 and the image saving device 28. By adopting this arrangement, the operations of inputting and of reserving the inspection content can become more efficient, and the load on the operator can be alleviated.
Note that a LAN, VAN, or other such format can be used as the construction for the network 34 which connects each of the above-mentioned devices to each other; however, in the present invention there is no particular restriction as to the method by which the network is constructed, and it is possible to use a communications network other than the ones mentioned.
The image information processing system incorporating the image information processing unit thereinto according to the present embodiment is basically constructed as described above, but the operations thereof are explained hereinafter, using as examples the inspection reservation from the IDT 32 and the process of executing the inspection based on this inspection reservation. Note that it is assumed here that a given patient has submitted an inspection prescription to the radiologist's reception desk, and the inspection reservation is to be performed by means of the IDT 32 mentioned above. The operation flow chart depicted in
When one of the image capturing conditions is completely established (i.e., case Y at step 103) then a request is made for the input of the next image capturing condition and this process is repeated (i.e., case Y at steps 103 and 104). When all of the image capturing conditions which have been planned are inputted, then the inspection request receiving function receives and registers these as being for a single inspection (step 105).
The content of the inspection reservation which is inputted as described above is transferred through the network 34 to the IIP 10A. Once the inspection reservation content has been transferred to the IIP 10A, then the content thereof is outputted as a display on the screen of the image display device 20, and also, instructions are automatically given to the radiation image capturing device 26 to capture the image.
That is, in
At the radiation image capturing device 26, when the image capturing actually starts the images which are captured are sent in sequence to the radiation image reading device 24, and the images are read. Here, as one example, a configuration is adopted in which the image which has been read (i.e., the image before it has been subjected to the image processing by the image information processing unit 16) is displayed in real time, and then when the entire image has been read and the image processing has been completely performed on this image, the above-mentioned image is replaced with the image that has been completely subjected to the image processing; however, the present invention is not limited to this configuration.
A comparison of the capture menu columns in
Note that the above-mentioned reordering of the capture menu (i.e., the tags) can also be performed in the case where the image is captured in a mistaken order. In such a case, in order to modify the relationship or the correspondences between the thumbnail images and the capture menu (i.e., tags), it is possible to apply a method in which the two thumbnail images which ought to be reordered are reordered by giving instructions for them, another method in which the thumbnail images which ought to be reordered are dragged (i.e., pulled and made to move) to the positions they would be in after the reordering, or the like.
Further, in
When other instruction buttons depicted in
In the case where the “end inspection” button 40d is pressed, an operation such as the one depicted in
The “new image” button 40e is for inputting instructions in the case where, for example, a new image capture is to be added which does not use the same image capture conditions which had been used up until that point. When this button is pressed, screens are displayed one after another for selecting conditions ranging from such things as the new region to be captured, to the angle and size of the image to be captured, so the operator only has to respond to these screens to set the new capture conditions.
The “retake image” button 40f is used when the operator sees the image which has been captured and displayed, notices that there is some sort of mistake, and wants to change the image capture conditions (i.e., such as in the case where the original settings were not correct, or because the operator discovered better image capture conditions after taking the image), or wants to retake the image without changing the image capture conditions (i.e., such as in the case where the subject moved inadvertently during the taking of the image).
The “add” button 40g is used in the case where an image capture is to be added in a similar fashion as in the case of the “new image” button 40e, but the difference from the case of the “new image” button 40e is that this button is an effective button in the case where the operator wishes to increase the quantity of the images captured using the same image capture conditions (i.e., such as the case where contrast media or such are used in the taking of the image, but the speed at which the contrast media are to move is predicted inaccurately as images are captured one after the other while the contrast media are moved).
Similar instruction buttons can be increased one after another as needed, and the content of the programs associated with the buttons can be altered appropriately.
Further, numbers can be applied to the image capture menu in sequence along the image capture menu (i.e., tags) array such as those depicted in the above-mentioned display screen (see
Note that the above embodiment is one example of the present invention, and, of course, the present invention is not limited to this embodiment, but various improvements and alterations can be made without departing from the essential scope of the present invention.
For example, in the above embodiment an example of the present invention is given in which the image information processing system includes the IIP which is connected to the network; however, the present invention can be used with an independent structure, as well.
As described in detail above, the present invention provides an image and information processor which can be used preferably even in the case where a single inspection uses several or more images, and it achieves an obvious effect such that when the images are to be handled they can be handled in units going from one image at a time to several or more images which are to be used in connection with a single inspection.
More specifically, whether the image and information processor is in the independent structure (stand-alone) or is connected to the network, the sequence of operations during the course of the inspection can be executed easily in either case, including the configuration of the image capture conditions (image capturing information) which are to be the content of the inspection, the step-by-step monitoring of the progress of the image capturing, the giving of the instructions for the image to be retaken in the case where a mistake is discovered, and thus a significant improvement becomes possible with respect to the efficiency with which the radiation images for the inspection are handled.
