Video imaging methods and apparatus. |
摘要 |
A video imaging system suitable for display of CT cine images stored in a hybridized memory includes both a dynamic random access memory (14) and video random access memory (16), the latter serving as a frame buffer. A memory address space is allocated between the dynamic and video random access memories. A non-linear, chained direct memory access control (22) enables the system to write a series of raster scan images directly from the video random access memory for display. The chaining provides a means for skipping over unused addresses at the end of a display line, thus maximizing utilization of the video random access memory.
