Abstract

PURPOSE:To speedily and surely input the ID information of an image necessary in searching an aimed image from an outside memory device by installing an image information searching processing means which reads out the image ID bar code on a film after image pick-up by an imager device and searches the recorded image corresponding to the image ID by an image memory device. CONSTITUTION:The data of a screen image of a CRT 24 is transported through a cable into an imager device 26, and displayed on a CRT 26a built in, and image pick-up is performed on a film 28a on the front surface by a camera. Accordingly, an imager film 28 having the same image to the screen image of the CRT 24 can be obtained. as for a bar code display part 16A among the imager films 28, an original image in or character information is inputted into a host computer 32, in the following to the optical head of a bar code reader 30 or scan part 30a, and the image data base of an image memory device 34 is searched by a previously prepared image information searching program, and the aimed image corresponding to the image ID information is read out, and displayed on a display device 36.

Description

[Detailed description of the invention] (b) Industrial application fields INDUSTRIAL APPLICATION This invention is utilized in the field of image display and image retrieval.

The present invention relates to a barcode search system for medical images.

(B) Prior Art Many medical imaging diagnostic devices are equipped with an image display device (display or CRT), and the images displayed on the CRT are used for diagnosis. Film images taken directly with a camera are also used for diagnosis.

When it is necessary to compare this film image with an image that can be called an original image in an external storage device such as a hard disk device or an optical disk device of the diagnostic device, it is displayed on the CRT screen.
A file number as image ID information taken on film is inputted using an input device such as a keyboard, and is searched by a combiator search processor connected to the storage device, thereby displaying the desired image.

(c) Problem to be solved by the invention As the capacity of storage devices connected to diagnostic devices increases and the number of connected storage devices also increases, the number of digits of file numbers as image ID information increases. Input using a conventional keyboard is time-consuming and prone to mistakes.

Furthermore, in many cases, image diagnosis focuses on changes in the area of interest between the previous examination and the current examination.

Therefore, it is particularly desirable for image diagnosis that the previous examination image can be displayed quickly and without error.

SUMMARY OF THE INVENTION An object of the present invention is to provide a medical image retrieval system that can quickly and reliably input the ID information of a target image using an easy-to-operate device when retrieving a target image from an external storage device. .

(d) Means for Solving the Problem The above object is to provide an image ID barcode display means for displaying image ID information as a barcode when displaying the image 411D information together with the medical image to be displayed on the CRT screen. , an imager device, a barcode reader, an image storage device for the displayed image, and an imager device.
This is achieved by comprising an image information search processing means that reads an image ID barcode on a film taken by the device and searches the image storage device for a recorded image corresponding to the image ID.

(E) Operation Display the file number of the image as IDtf information in barcode on the CRT screen with the medical image in the center and other suitable places, and capture this with the camera using the imager device. -・Film is obtained. When searching for the same recorded image from an image storage device, use a handy barcode reader to scan the barcode display on the imager film and it will be converted to the original image ID information. , is input to the image information search processor, and the desired image is displayed on a separate display.

(f) Example A preferred embodiment of the invention will be explained based on the drawings.

FIG. 1 is a diagram illustrating the process of obtaining an imager film according to the present invention, and FIG. 2 is a diagram schematically illustrating the configuration of an image information retrieval processing apparatus according to the present invention.

In FIG. 1, 10 is a medical image generator or image memory, 12 is a grayscale pattern generator or pattern memory, 14 is a character information generator or character information memory, and 16 is a character information generator 14.
A barcode generator 18 converts only the image ID information into a barcode among the outputs of the mixer 18, which combines the output data of the information generators 10, 12, 14, and 16.

Reference numeral 20 is a D/A converter for this synthesized digital data, and as a result, the medical image 10A, grayscale information 12A, character information 14A, and barcode of the image ID of the image 1OA are displayed on the screen of the CRT 24 as shown in the figure. displayed at the same time.

A barcode is a code that is displayed using lines with different line widths and line spacing, and such barcodes are displayed on products and are used in POS terminals, postal classification, inventory management, library management, etc. has been done.

The screen image data of the CRT 24 is sent to the imager device 26.
is transferred to the built-in CR via a cable (not shown).
T26a is displayed and photographed by a camera (not shown) on the film 28a in front of it. This allows CRT
Image save film 28 with the same image as screen 24
is obtained.

In FIG. 2, of the imager film 28,
When the optical head or scanning section 30a of the barcode reader 30 is traced on the barcode display section 16A, the original image ID or character information is input to the host computer 32, and the image is stored by a prepared image information search program. The image database of the bag M34 is searched, and the target image corresponding to the image ID information is read out and displayed on the display device 36. In this case, the data in the image storage device 34a in FIG. 1 is first transferred to the image storage device 34 in FIG. 2.

Note that the image storage device 34 is a hard disk, and the image ID
If it consists of two digits representing the partition of the hard disk and four digits representing the record number, then
The image storage device 34 can have as many partitions as can be identified by two digits. In addition, a plurality of image storage devices 3
When 4 are connected in parallel, the image ■D may be increased by one digit for this purpose.

In order to read the barcode display section of the imager film 28 using a commercially available barcode reader, the background of the display section must be white. For this purpose, the barcode generator 16 requires a controller that specifies a white background area and outputs white background data.

In addition to the hard disk, the image storage device 34 also includes:
An optical disk or other device that can be connected to a computer is used.

(g) Effects According to the present invention, a target image can be obtained easily, quickly and accurately from a huge amount of stored images, and the efficiency of diagnosis is improved. Furthermore, by displaying the patient's medical record number in the form of a barcode, it can be linked to other patient information and used for integrated information management.
