A system for displaying selected images on a video display device is provided. One or more sources of image frames are included which sources may be digital or analog and which sources may present pixel data in different selected formats. A frame memory is provided which is adapted to store a plurality of memory frames each of which may store one or more image frames to be displayed. Image frames are selectively stored in the memory frames of the frame memory in the format in which they are received. The images may be stored in full size or may be compressed for windowing display and selected information concerning image frames may be utilized to control the mapping of values stored for the pixels of the image frames. A display frame may be formed of two or more compressed image frames with each image frame being read out from a selected memory frame which memory frame may be independent of or the same as the memory frame for other read out images. Certain images may contain two or more different types of information which may be selectively processed when read out from a frame memory to cause the content of such multiple information images to be displayed as multiple separate images containing the content of the image frame in various permutations and combinations. Color mapping using the same or different criteria may also be provided, with the color mapping being independent for each of the image frames being simultaneously displayed.

Method and apparatus for the simultaneous display of one or more

The sampling volume of a pulsed Doppler system is increased to a length greater than that corresponding to one pulse by sampling the reflections of each launched pulse a plurality of successive times and accumulating the samples.
