Abstract
The preferred embodiments include a method and system for simultaneously displaying diagnostic medical ultrasound image clips on one or more monitors without degradation in display frame rate. In one preferred embodiment, compressed ultrasound image frames are sent to a video display system for decompression. Because compressed image frames are sent, there is no degradation in frame rate caused by the bandwidth limitations of the CPU/video display system bus. Further, because the video display system decompress the compressed image frames faster than decompression software executed by a CPU, there is no degradation in frame rate caused by power limitations of the CPU. The video display system can also be used to control the frame rate, luminance, and size of individual ultrasound image clips. The preferred video display system described herein finds particular utility in ultrasound examinations performed in cardiac, radiological, obstetrical, and neo-natal ultrasound examinations.
