Abstract

PURPOSE:To diagnose easily the change of a person to be examined from past conditions to present conditions by inputting the code of the person to be examined to read out a diagnostic image of the person to be examined from a memory where plural diagnostic images are stored and displaying this readout image together with an image obtained from diagnosing endoscope. CONSTITUTION:The image of the inside of a coelom obtained by the endoscope is processed by a TV camera 2 and is displayed as an endoscope image In on a monitor 6. Meanwhile, a card PC of the patient is inserted to a card reader 4, and data corresponding to data of the card PC is read out from a large-capacity memory 3 through an input/output interface I/F by a CPU and is displayed as an image Io together with said image In on the monitor 6. Data and indication contents given from the external are displayed on a display part Ip of the monitor 6. An auxiliary designating means 5 selects images of another part or past images as required and displays them as the image Io. Thus, present conditions and past conditions of the patient are compared with each other in real time to make accurate diagnosis easy.

Description

[Detailed Description of the Invention] Technical Field The present invention relates to: ! The present invention relates to an endoscope image reproducing device used for mirror diagnosis.

Conventional technology Conventionally, when diagnosing using internal *a, internal? ! After photographing the mirror examination image with the -H camera and developing it, ?
l! For subjects who are diagnosed using mirror images and who have been diagnosed continuously, compare and contrast with previously taken and saved endoscopic images as necessary. was common.

However, in this case, the comparison with past endoscopic images is
In actual endoscopic examinations, the patient relies on memory and the like, and it is not possible to diagnose diseases, disease progression, etc. that require the above-mentioned comparisons in real time. In other words, since the diagnosis based on the above comparison is made after the photographs and film have been developed, in many cases there is a lag of 2 to 3 days before diagnosis, and even if immediate treatment is required, treatment is delayed. Something happened. Furthermore, since the necessary field of view setting during endoscopic examination cannot be directly compared, it is necessary to rely on memory, which results in poor examination and diagnosis efficiency, and it is difficult to make an accurate diagnosis quickly. It was a hindrance.

Purpose The purpose of the present invention is to analyze, in real time, the endoscopic images at that point and the endoscopic images obtained in the past during actual endoscopic examinations for patients who are continuously being diagnosed. Is it possible to make a comparative diagnosis? J! An object of the present invention is to provide an image reproduction device for mirror paintings.

Overview The present invention provides for inputting identification data for identifying a subject through an identification data input means, and reading a diagnostic image of the subject from a storage means stored therein by a reading means responsive to the identification data input means. The past diagnostic images corresponding to the identification data are read out, and the endoscopic image taken by the endoscopic camera and the image read out by the reading means are displayed side by side on the image display means. This system is characterized by allowing endoscopic images to be compared with past images during endoscopic examination.

Example The figure shows the configuration of an embodiment of the present invention.

In the figure, the distal end insertion portion (not shown) of the endoscope 1 is inserted into the body of a subject. TV (television)
The camera 2 is an endoscope camera that captures an image inside the body obtained by the endoscope 1. The large-capacity memory 3 is a storage means such as an image file using an optical disk, a magnetic disk, etc., and stores past diagnostic images of the subject. In this case, the image data of the diagnostic image is stored in the large-capacity memory 3 in association with identification information indicating the subject and, if necessary, the imaging time, body part, etc. In this case, the card reader 4 is a data reading means that reads and inputs the main identification data from a medical examination card PC made of a recording medium card such as a magnetic card on which main identification data indicating the subject is recorded. The auxiliary designation means 5 is for inputting auxiliary identification data for selecting an image other than the image initially selected by the main identification data input by the card reader 4, and for example, a body part button for inputting body part designation data. etc. Therefore, in this case, the card reader 4 and the auxiliary designation means 5
This constitutes an identification data input means. The monitor 6 is an image display means that displays the image read out from the large-capacity memory 3 and the image captured by the TV camera 2 side by side. (It may be information or side) displays instructions or data given from the outside, or other information related to the displayed image.

The large-capacity memory 3, card reader 4, auxiliary designation means 5, and monitor 6 are connected to a bus B connected to the central processing unit CPU via an input/output interface I/F. Memory R used for processing
OM (read only memory) and RAM (random access memory 5---readable/writable memory) are combined. These central processing unit CPU single output interface ■/F1 memory R
A processing/control device 7 is constituted by OM and RAM.

In such a □ configuration, when an endoscopic image is captured by the TV camera 2, the endoscopic image that is being examined, that is, being captured, is displayed as is on the monitor 6.The new endoscopic image In that is being captured is For example, as shown in the figure, it is displayed on the right half of the screen of the monitor 6.

In the case of examination of a patient who has been examined in the past,
For example, prior to the examination (imaging) of a new endoscopic image In,
Alternatively, by loading the examination card PC into the card reader 4 during the examination, past endoscopic diagnostic images of the subject are displayed on the monitor 6.

The main identification data of the subject is read by the card reader 4, and based on the main identification data, past endoscopic diagnostic images of the subject are retrieved from the large-capacity memory 3 and read. This is done by outputting the data, transferring it to the monitor 6, and displaying it. This operation is executed by the operation of the processing/control device 7 based on the processing of the central processing unit CPU 6 through the input/output interface I/F. The above past endoscopic image ■0 is
For example, as shown in the figure, it is displayed on the left half of the screen of the monitor 6 alongside the new endoscopic image In being captured. At this time, as the past endoscopic image IO, for example, in principle, the latest past endoscopic image is read out and displayed.

In this way, the new endoscopic image In being imaged displayed on the monitor 6 can be juxtaposed with it, and the patient can be examined while comparing it with the previous endoscopic image ■o displayed on the monitor 6.

Furthermore, in the course of the medical examination, if you wish to refer to and compare endoscopic images other than the endoscopic image currently displayed on the monitor 6 among the past endoscopic images of the subject stored in the large-capacity memory 3. By pressing, for example, a region designation button of the auxiliary designation means 5, auxiliary identification data indicating the relevant region is input,
The endoscopic image of the corresponding region is read out from the large-capacity memory 3 in the same manner as described above, and the past endoscopic image is displayed on the monitor 6.
Displayed as 0. Of course, as long as the corresponding image data is stored in the large-capacity memory 3, it is also possible to reselect another region and display the endoscopic image of that region as the past endoscopic image ■0. It is also possible to display even earlier endoscopic images of the subject by providing the auxiliary designation means 5 with designation information input means for this purpose.

As the reference image displayed on the left half of the display screen of the monitor 6, any image physically stored in the large-capacity memory 3 can be displayed. It may be possible to select not only the endoscopic image of another patient but also the endoscopic image of another subject or other images as the reference image.

Further, around the displayed diagnostic image on the display screen of the monitor 6, for example, in the lower area 1p as shown in the figure, data such as the patient's name related to the operation of the card reader 4 and the auxiliary designation means 5, etc. Alternatively, the contents of the operation instructions, etc. are displayed as appropriate.

In addition, the past endoscopic image ■0 and the new endoscopic image being imaged? !
The mirror image In can be partially enlarged or reduced by image processing, or displayed with special processing (for example, spatial filtering, smoothing or edge enhancement by other processing, etc.) as necessary. Although not explicitly stated, the in-vivo image captured by the TV camera 2 through the inner body 11 is stored in the large-capacity memory 3 in association with the corresponding body part and other identification information as necessary.At this time, an appropriate optical It is also possible to store the image after processing or electronic image processing together with identification information to that effect.These processings are also performed based on the operation of the processing/control device 7.

In this way, a new endoscopic image in which the internal image of the subject obtained by the endoscope 1 is captured by the TV camera 2,
Past endoscopic diagnostic images I read out from the large capacity memory 3
It is possible to perform examinations and diagnoses by displaying this on a monitor side by side with O and comparing the two in real time. Therefore, it becomes possible to make a diagnosis at the same time as the endoscopic examination, and it becomes easy to compare and contrast with past endoscopic images, so that a quick and reliable endoscopic diagnosis can be realized. In this case, since a medical examination card PC (corresponding to a so-called medical examination ticket) consisting of a magnetic card or the like is used to input the primary identification data, inputting the primary identification data is extremely quick and easy. Mistakes are less likely to occur.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without changing the gist thereof.

For example, the main identification data may be input using a medium reading means that reads an identification data storage medium other than a magnetic card as the identification data input means. Further, not only the main identification data for identifying the subject but also other auxiliary identification data may be inputted using such a medium reading means or the card reader. moreover,
The main identification data or the main identification data and other auxiliary identification data may be input using an operation input means such as a keyboard. Of course, it is not always necessary to input auxiliary identification data other than the main identification data.
If there are only a few types of images stored in the large-capacity memory 3, only the main identification data, that is, the data identifying the subject 10-, is sufficient.

Of course, the monitor 6 as an image display means may be configured with a plurality of displays, or a single display may be used to display divided images to display the old and new images. J! Mirror images may be displayed side by side.

Effects of the Invention According to the present invention, identification data for identifying a subject is inputted from the identification data input means, and is inputted from the storage means storing the diagnostic image of the subject to the identification data input means. The responsive reading means reads out past diagnostic images corresponding to the identification data, and the image display means displays the endoscopic image during diagnosis taken by the endoscopic camera and the image read out by the reading means side by side. By doing so, it is possible to compare and diagnose in real time the endoscopic image at that point and the endoscopic image obtained in the past during actual endoscopic examination for patients who are continuously being diagnosed. It becomes possible to provide an image reproduction device for mirrors.
