Method for displaying desired message in display unit of data processing apparatus for various processes

Two different CT images are stored respectively in a primary image memory and a secondary image memory. For image display, the secondary image is inset in a desired rectangular region in the main image memory so that the two images can simultaneously be displayed. The data for the two images to be displayed can be independently subjected to various types of processing in real time, such as window or level processing, blinking for flashing displayed image data pixels in a particular CT value zone, and reverse video operations.
