Abstract

PURPOSE:To easily recognize a radiographic picture to be read and improve the reading efficiency of a radiographic picture reading by displaying the subject picture in a gradation picture and the other pictures in a low-density picture. CONSTITUTION:When the information peculiar to a patient is inputted to an input device 5, a CPU 6 writes lowest-density data in all display memories 7a-7c in response to a request and surface sections 9a-9c are respectively displayed with at low density through D/A converters 8a-8c. The CPU 6 then transfers subject picture data transferred to an image memory 3 to the display memories 7a and 7b and rewrites the lowest-density data in picture data. The data stored in the memory 7c are left as the lowerst-density data. When only a radiographic picture to be read is displayed and the other unnecessary display sections are displayed in the low-density state in such way, a radiographic picture reading physician can easily recognize the radiographic picture to be read and his reading efficiency is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Field of Industrial Application) The present invention relates to an image display device including a plurality of display sections.

(Prior art) In recent years, various digitalized medical images such as X-ray fluoroscopic images,
The image is displayed on the monitor, and the first diagnosis is being performed. Furthermore, a plurality of TV monitors are used to display images of the same type to be compared on the plurality of TV monitors in order to improve the efficiency of image interpretation 1 diagnosis.

(Problems to be Solved by the Invention) Not all TV monitors are used during image interpretation 1 diagnosis. For example, if there are fewer images of the same subject (also referred to as a patient) than there are TV monitors, the image interpretation 9
Even if an image of a subject to be diagnosed is read out, the image of the previous subject may remain displayed on the TV monitor.

For this reason, there is a problem that there is a risk of misinterpreting the image to be interpreted.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an image display device that improves the efficiency of image interpretation.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a method for displaying a plurality of grayscale image data of the same type among a plurality of captured grayscale image data based on a display operation. In an image display device capable of displaying images on a display section, low-density data is temporarily stored in a plurality of display memories connected correspondingly to the plurality of display sections, and based on the display operation described in 1. display control means for writing the same type of grayscale image data into the display memory according to the number of the grayscale image data after writing, and displaying each data stored in each display memory on each of the display sections; It is characterized by having.

(for production) The operation of the device having the above configuration will be explained.

When a display operation is performed on the device, the display control means:
Write low concentration data to each display memory. Next, the display control means writes the same type of grayscale image data into each display memory.

Here, if the number of grayscale image data of the same type is smaller than the number of display memories, the display memory contains a mixture of memory for storing grayscale image data and memory for low-density data, and each display A grayscale image and a low-density image are displayed in the area. Since the gradation image shows gradation more clearly than the low-density image, the interpretation doctor can easily recognize which image should be interpreted, and the interpretation efficiency is improved.

(Example) Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a schematic diagram of an apparatus 1 according to an embodiment of the present invention.

This device 1 includes an image memory 3 that stores various medical images taken and digitized for a large number of subjects by various modalities such as X, IICT device, MHI device, etc.
, a main memory 2 that stores incidental information of images stored in the image memory 3, and a plurality of (three in this example) display systems 4 (4a, 4b, 4c) that display images.
, an input device 5 that performs request operations such as image display requests, input operations of patient-specific information (a type of incidental information) to be interpreted, etc., and an input device 5 that controls each part of the water device 1 and displays display control for the display system 4. It has a CPU 6 to perform the operations.

The display system 4 includes a first display system 4a and a second display system 4b.
, and a third display system 4c. Each of the display systems 4a to 4c has a similar configuration, and includes display memories 7a to 7c, D/A converters 8a to 8c, and TV monitor 9a, respectively.
to 9c.

The CPU 6 is an input device! When one piece of patient-specific information, such as patient ID information, is input to 10, the incidental information of the image in the main memory 2 is searched using this ID information as a search key, and the corresponding image data is read out and stored in the display memories 7a to 7c. I am trying to transfer it to and memorize it.

The types of images stored in the main memory 2 are as follows:
Subject, photographing direction of the patient, such as frontal direction, lateral direction, etc., posture of the patient, such as supine, prone, etc., modality, date of photographing, body part to be photographed, such as head, abdomen, etc., and whether or not the photograph has been taken, etc. There is.

Next, the functions and effects of the embodiment device 1 having the above configuration will be explained with reference to FIG. 2 as well. It is assumed that an unread image of the same patient is displayed for each display operation.

It is also assumed that images Do to D3 of the previous patient are displayed on each of the display sections 9a to 9c, as shown in FIG. 2(a).

First, when the interpretation doctor displays the next patient's images D Enter unique information and request image display.

The CPU 6 writes the minimum density data into all display memories 7a to 7c based on the patient-specific information and image display request input to the input device.

The lowest density data written in each display memory 7a to 7c is transmitted through each D/A converter 8a to 8c.
As shown in FIG. 2(b), the entire display screen of each of the display sections 9a to 9c is displayed with a reduced density.

Next, the CPU 6 transfers the image data transferred to the image memory 3 to the display memories 7a and 7b.

Two display memories 7a to which image data has been transferred
, 7b are rewritten from the lowest density data to image data, and the content of the other display memory 7c remains the lowest density data.

The contents of each display memory 7a to 7C are stored in the display memory 7a to 7C through each D/A converter 8a to 8C as described above.
As shown in C), image data is displayed on the two display sections 9a and 9b, and the entire surface of the other display section 9C is displayed in a low density state.

The interpretation doctor then interprets the images displayed on the display sections 9a and 9b. On the display sections 9a to 9C, only images to be interpreted are displayed, images of the previous patient are not displayed, and screens of display sections that are not necessary for image interpretation are displayed in a low density state. Therefore, the interpretation doctor can easily recognize which image should be interpreted, so there is no risk of mistaking the target of interpretation, and the efficiency of image interpretation is improved.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be variously modified without changing the gist thereof. For example, the low-density data may be such that the screen of the display unit that is not necessary for image interpretation has a lower density than the grayscale image that is necessary for image interpretation.

[Effects of the Invention] According to the present invention detailed above, when the number of grayscale image data of the same type is smaller than the number of display sections, the screen of the display section that is not used for image interpretation becomes a low density state. Since it is possible to easily interpret a grayscale image, it is possible to provide an image display device that improves the efficiency of image interpretation.
