JPH10225441A - Method for selecting display image in medical image observing device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily discriminate whether respective images are already read or not and to prevent the reading omission of the recorded images by executing list-display so as to discriminate whether the respective images are already read or not when the list of the plurality of images recorded in a recording means are displayed in a display means. SOLUTION: CPU 20 of a medical image observing device 10 records index information (patient names and photographing dates, etc.) which is transmitted from a network together with the images in a magnetic disk 12. When a doctor reads the image, index information recorded in the magnetic disk 12 together with the images is read at first and index information is list-displayed in a monitor 18. At this time, CPU 20 refers to a recorded image reading sign and executes display with a mark (parenthesis mark) which indicates that the image is read in the read image. When the reading of the image which is selected by the doctor and displayed in the monitor 18 is ended, the image reading sign is rewritten into already read image data.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for selecting a display image in a medical image observation apparatus, and more particularly, to a method in which a medical image is randomly transmitted to a medical image observation apparatus via a network or the like so as to prevent omission of interpretation. The present invention relates to a display image selection method in a medical image observation device capable of selecting and displaying an image.

[0002]

2. Description of the Related Art In an image management system currently used in hospitals and the like, an image taken by an X-ray examination apparatus, a CT apparatus or the like is sent to a medical image observation apparatus via a network, and this image is sent to a medical image observation apparatus. On a recording device such as a magnetic disk. The doctor reads this image from the magnetic disk and reads it on the monitor.

In such a system, a photographed image is transmitted at random through a network.
Doctors need to read all the images that are sent,
Put the paper with the list of images to be sent in advance at hand, check the read image with a pencil,
The image that has been read and the image that has not been read are discriminated.

[0004]

However, the photographing is not always performed in the order of reservation, and there are people who do not come for inspection or people who come in for inspection by jumping. The sent image may not correspond properly. Further, there are cases where the images are not sent to the hand in the order described in the list. For this reason, the method of checking the list of papers with a pencil and discriminating between a read image and an unread image was not sufficient to prevent image leakage.

Further, there is a problem that it is troublesome to judge whether or not the interpretation has been performed while looking at a list of papers.

The present invention has been made in view of such circumstances, and a doctor selects an image so that a medical image randomly transmitted to a medical image observation apparatus via a network or the like is not missed in interpretation. It is an object of the present invention to provide a display image selection method in a medical image observation device capable of displaying.

[0007]

The present invention achieves the above object by providing a plurality of images obtained by a diagnostic apparatus,
Identify the plurality of images and record an index including an interpretation sign indicating whether each image has been interpreted or not, in a recording unit, and display a list of the plurality of images on a display unit based on the index. At this time, based on the interpretation sign, each image is displayed as a list so that it is possible to determine whether the image has been interpreted or not, select an image to be interpreted with reference to the list displayed on the display means, and select the selected image. The image is displayed on the display means, and when the interpretation of the image displayed on the display means is completed, the interpretation sign of the image is rewritten to have been interpreted.

According to the present invention, when a list of a plurality of images recorded in the recording means is displayed on the display means, the list is displayed so that it is possible to determine whether each image has been interpreted or not based on the interpretation sign. With this configuration, it is possible to easily determine whether each image has been interpreted or not, based on the list displayed on the display unit. For example, it is easy to select only unread images and perform image interpretation. Thus, it is possible to prevent the image recorded on the recording unit from being missed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a display image selection method in a medical image observation apparatus according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a diagram showing a configuration of a medical image management system to which the present invention is applied. As shown in the figure,
For example, an image film obtained by an X-ray inspection device or the like is converted into digital data by a film scanner 1 and sent to a medical image observation device 10 via a network. Similarly, images acquired by the CR device 2, the MRI device 3, the CT device 4, the DSA device 5, the nuclear medicine diagnostic device 6, and the like are sent to the medical image observation device 10 via the network 7. The medical image observation device 10 records and saves images sequentially transmitted from these diagnostic devices via the network 7 on the magnetic disk 12.

The doctor selects a desired patient image from a plurality of images stored on the magnetic disk 12 using an input device such as a keyboard 14 or a mouse 16 and displays the image on a monitor 18. Diagnose the patient while looking at the images.

FIG. 2 is an internal configuration diagram of the medical image observation apparatus 10 to which the present invention is applied. As shown in the figure,
The medical image observation apparatus is composed of an ordinary computer system, and includes a computer main body (CPU 20: central processing unit), a magnetic disk 12, a keyboard 14, a mouse 16, and the like.
And the like, and a monitor 18. The computer main body (CPU 20) is connected to the network 7 via the communication interface 22, and records an image sent via the network 7 on the magnetic disk 12.

The CPU 20 records index information (for example, information related to each image data such as a patient name and a photographing date) sent together with the image from the network 7 on the magnetic disk 12 together with the image.

When a doctor interprets an image recorded on the magnetic disk 12, the CPU 20 first reads out index information recorded on the magnetic disk 12 together with the image.
The index information such as the patient name of the image recorded on the magnetic disk 12 is displayed in a list on the monitor 18 (display of a patient list screen and an image list screen). At this time, CPU
Reference numeral 20 refers to an image interpretation signature recorded on the magnetic disk 12 (the image interpretation signature will be described later), and a mark (parenthesis mark) indicating that the image interpretation has been completed is added to the list of images that have been interpreted. To display on the monitor 18. This makes it possible to easily determine whether image data has been interpreted or not.

The doctor refers to the list displayed on the monitor 18, detects an unread image from the images recorded on the magnetic disk 12, and reads the unread image using the keyboard 14 or the mouse 16. Select a shadow image (or select a read image if necessary).

The CPU 20 reads an image selected by the doctor from the magnetic disk 12 and displays the image on the monitor 18. Then, when the doctor finishes the interpretation, the interpretation sign corresponding to this image is rewritten to the interpreted data. As a result, this image is processed as a read image when the next list is displayed.

FIG. 3 is a diagram showing a memory area structure inside the magnetic disk of the medical image observation apparatus. FIG.
The magnetic disk 12 of the medical image observation device 10 shown in FIG.
Are divided into an image area and an index area as shown in FIG. As described above, the image area is an area for recording an image (image data indicating an image) transmitted via the network 7. The index area is an area for recording index information of an image recorded in the image area. The image recorded in the image area and the index area and the index information related to the image are recorded in a memory in association with each other. Therefore, an image corresponding to the index information can be read from the memory from the index information.

In the index area, as shown in FIG. 3C, index information of the images recorded in the image area is recorded in order from the first person to the n-th person. When a plurality of images are taken for one examination performed on each patient, index information is created for each examination and 1
A plurality of images correspond to one index information.

As shown in FIG. 3D, the index information is composed of data such as an examination number, a patient number, a patient name, an examination date, an examination name, the number of images, an image interpretation sign, and the like. The examination number is an identification number given for each examination, and the patient number is an identification number given to a patient who has undergone this examination. The patient name indicates the name of the patient. The inspection date indicates the date of the inspection on which the image was captured, and the inspection name indicates the name of the target part (for example, chest, abdomen, etc.) on which the image was captured. The number of images indicates the number of images captured by this inspection, that is, the number of images recorded in the image area by this inspection.

The interpretation sign indicates whether or not a specific doctor has interpreted the image recorded in the image area.
(E) shows the structure of the interpretation sign data. As shown in the figure, the interpretation sign is data composed of 16-bit 0s and 1s, and is recorded in a 16-bit memory area. Each bit is assigned to a specific physician. If the bit is 0, it indicates that no interpretation has been performed by the physician assigned this bit (unread), and if the bit is 1, this bit has been assigned. Indicates that the interpretation has been completed by the doctor (interpreted). For example, when the doctor A is assigned to the first bit, when the doctor A interprets the image data corresponding to the interpretation sign, the data of the first bit of the interpretation sign becomes 0 as shown in FIG. From 1
Is rewritten as When the doctor B is assigned to the 16th bit and the image corresponding to the interpretation sign is interpreted by the doctor B, the 16th bit data of the interpretation sign is changed from 0 as shown in FIG. Rewritten to 1. Similarly, 1 is stored in the data area of one interpretation signature.
Unread and read information of six doctors (corresponding to the number of bits in the memory area of the reading sign) is recorded.

The memory area of the image interpretation sign is created when the image data and index information sent via the network 7 are recorded on the magnetic disk 12, and in the initial stage, the data of each bit of the image interpretation sign is 0. Is initialized to If the interpretation sign of, for example, eight doctors is sufficient, an 8-bit memory area is allocated and the number of bits can be appropriately changed as needed.

Next, an image selection method for displaying an image stored on the magnetic disk 12 of the medical image observation apparatus on the monitor 18 will be described in detail. First, the CPU 20 displays a doctor code input screen as shown in FIG. The doctor code is an identification number of a doctor who specifies a doctor to be interpreted, and the doctor who performs image interpretation uses the keyboard 14 or the mouse 16 to enter a doctor code assigned to the doctor. For example, when the code of the doctor who performs image interpretation is 1, the block of “DOCTOR1” 100 displayed at the bottom of the screen shown in FIG. In addition, when the interpretation sign is not used, that is,
In the case where the interpretation to be performed this time is invalidated, the block of “NOT SIGN” 102 displayed at the bottom of the screen is clicked with the mouse 16.

After entering the doctor code, the CP
U20 displays a patient list screen (patient list screen) as shown in FIG. This patient list screen displays a list of patients whose images are recorded on the magnetic disk 12. The patient list screen includes a list display number (NO.) 104 followed by a patient patient number (ID NO.). .) 106, Name (NAME) 10
8, birthday (BIRTH DATE) 110, age (A
GE) 112 and gender (SEX) 114 are displayed. These pieces of information are recorded in the index area of the magnetic disk 12 as index information.
Reads out this information from the index area and displays it in a list on the monitor 18. If there are two or more index information items for the same patient, they are displayed together in one list display number so that the display is not duplicated.

The physician selects one or a plurality of candidate patients of the image to be read from the patient list by clicking with the mouse 16. At this time, the list display number of the selected candidate patient is shaded. Then, when the selection is completed, the “IMAGE LIST” displayed at the bottom of the screen is displayed.
The block 116 is clicked to move to the next screen (image list screen).

On the patient list screen shown in FIG. 5, when the block of "ALL" 118 displayed at the bottom of the screen is clicked, all patients are selected as candidate patients. When the number of patients is large and not all patients are listed on one screen, “NEXT PAGE” 120,
Clicking on the block of “BACK PAGE” 122 displays the patient list of the next or previous page. Clicking on the block of "SELECTTRV." 124 executes a search by patient number and patient name, and clicking on the block of "EXAM RTRV." 126 executes a search by examination date. "ID
NO. When the block of "SOTR" 128 is created, the list is displayed in the order of the patient number.

As described above, when the candidate patient to be interpreted is selected by the doctor and the block of the "IMAGE LIST" 116 is clicked, the CPU 20 next sets the image of the selected candidate patient as shown in FIG. An image list screen (image list screen) showing details of the image contents is displayed. As shown in FIG. 6, a patient number (ID N) is displayed on the image list screen after the list display number (NO.).
O. ) 132, examination (EXAM.DATE) 134, examination device (DVC) 136, imaging part (LOCATIO)
N) 138 and the number of images (IMAGE) 140 are displayed. These pieces of information are recorded in the index area of the magnetic disk 12 as index information.
The PU 20 reads out the index information of the candidate patient selected on the patient list screen from the index area and displays the index information on the monitor 18 in a list.

The doctor refers to the image list screen and selects an image to be interpreted by clicking with the mouse 16. At this time, the list display number of the selected image is shaded. When the selection is completed, the user clicks on the block of “DIAG” 142 displayed at the bottom of the screen.

When the image list screen is displayed, the CPU 20 refers to the interpretation sign of the index information described above, and the doctor who is currently reading the image interprets each image recorded on the magnetic disk 12 in the past. Is detected. That is, in the interpretation sign, it is detected whether the bit corresponding to the doctor code input first on the doctor code input screen is 0 or 1. If the interpretation has been completed, that is, if the above-mentioned bit of the interpretation sign is 1, the CPU 20 displays the list display number of the image in parentheses (if not, the list display number of the image is displayed). Only the number is displayed on the image list screen).

Thus, the doctor can know that the image has been read by the parentheses attached to the list display number. Therefore, when it is desired to read only unread images, an image with a list display number without parentheses may be selected. Conversely, when there is an image with a list display number without parentheses, Can easily know that the image has not been read, and can prevent omission of reading.

The "ALL" 14 displayed at the bottom of the screen
When block 4 is clicked, the unread images other than the already read images are selected as the images to be read, and all the display numbers of the unread images are shaded. In addition, "SH
Click on the “OW LIST” 150 block,
The read image list is deleted from the image list, and only the unread image list is displayed on the screen. When the number of images is large and not all image lists are displayed on one screen, the “NEXT PAS” displayed at the bottom of the screen is displayed.
Clicking on a block of “GE” 146 and “BACK PAGE” 148 displays a list screen of the next or previous page. Also, "PATIENT LIST"
Clicking on the block 152 returns to the patient list screen.

When the image to be interpreted is selected as described above and the block of “DIAG” 142 displayed at the lower part of the screen is clicked, the CPU 20 then transfers the selected image to the image on the magnetic disk 12. Read from the area,
As shown in FIG. 7, up to four images are displayed in an area on the screen divided into four (display of an image display screen). At this time, C
The PU 20 first reads the image with the smallest list display number from the image area of the magnetic disk 12 among the images selected on the image list screen, displays the image on the image display screen, and displays the patient name and the patient name of the image. The index information such as the number is displayed at the top of the screen.

The doctor diagnoses the patient by looking at the image displayed on the image display screen. Then, when the interpretation is completed, the user clicks on the “SIGN” 154 block displayed at the bottom of the screen and inputs the signature of the interpreted image. C
When the block of “SIGN” 154 is clicked, the PU 20 sets the bit data corresponding to this doctor in the interpretation sign of the displayed image to 1, and records that the interpretation has been completed in the interpretation sign.

If there are four or more images corresponding to one list display number, drag the scroll bar displayed at the top of the screen to slide the screen horizontally, and place the remaining images on the screen. Can be displayed. Or, "IMAGE CHANG" displayed at the bottom of the screen
The next image can be displayed by clicking on the block "E" 156.

When the doctor finishes reading the image displayed on the image display screen as described above and reads the image of the next list display number selected on the image list screen, the doctor displays the image at the bottom of the screen. "FOLDER CHANG

As described above, according to the medical image observation apparatus, it is possible to determine whether each image has been interpreted or not on the selection screen (image list screen) for selecting the image to be interpreted. It is possible to easily select only unread images and read the unread images one after another.
If necessary, only unread images can be displayed in a list on the image list screen, and all of these unread images can be selected at once as images to be read. Therefore, it is possible to prevent the image recorded on the magnetic disk 12 from being missed. Further, as described above, since the interpretation sign indicating whether the interpretation has been performed or not has been performed, the information of a plurality of doctors can be recorded by a plurality of bits (16 bits) of data. Can be interpreted without fail. Therefore, a plurality of doctors can read one image data without omission, and it is possible to prevent a disease from being overlooked due to a plurality of doctors.

As described above, in the above embodiment, unread images can be identified by adding parentheses to the list display number on the image list screen. However, the present invention is not limited to this. You may make it possible to distinguish between a read image and an unread image. Further, only unread image data may be displayed on the image list screen unless otherwise specified.

In the above-described embodiment, it may be possible to determine whether the image has been read and whether the image has not been read on the patient list screen. For example, if all the displayed patient images have been read, parentheses are added to the list display number of the patient list.
