Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image data display device, and more particularly to an image data display device having an improved image data display speed.

[0002]

2. Description of the Related Art Recently, more advanced image diagnosis has been performed using medical equipment such as an X-ray CT scanner and a magnetic resonance imaging apparatus.

It is desirable that the image data obtained by these medical devices can be effectively used for medical diagnosis by storing them in a database and reading them out from the database later.

In the medical field, PACS (Picture Archivi
A medical image storage transmission display system called ng and Communication Systems) has been researched and developed, and image data stored in a database can be displayed as an image on a monitor at any time.

[0005]

Here, while some original image data created by a medical device has a pixel number of 8000 × 8000, for example, the pixel number of a monitor is usually 1000 ×. Since the number of pixels is 1000, in order to display the original image data on the monitor, the format of the original image data must be converted to the display format.

Therefore, when the conventional image data display device represented by PACS is used to display the original image data on the monitor, it takes time for format conversion each time it is displayed on the monitor.

Such a situation not only hinders rapid image diagnosis, but also causes a decrease in utilization efficiency of the entire network when using the network.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an image data display device capable of reducing the display speed of image data.

[0009]

In order to achieve the above object, the image data display device of the present invention, as set forth in claim 1, reads the original image data by the image reading means and displays the read original image data as an image. The data processing means performs format conversion to create display image data, and the original image data and the display image data are configured to be stored in the image data storage means, and the stored display image data is stored as image data. The display means is configured to be displayable.

[0010]

The display image data in which the format of the original image data is converted into the display format is created in advance and stored in the image data storage means. It is sufficient to display the data, and it is not necessary to convert the format of the original image data.

Therefore, the time for displaying as an image can be greatly saved.
