Abstract
A technique for increasing the display frame rate of a medical ultrasound imaging system. The system receives trigger signals, each based upon the occurrence of a predetermined event in a subject's cardiac cycle, such as an R-wave. In one technique, in response to each trigger signal, the ultrasound system acquires a series of frames, each frame comprising data representing an image of a portion of the subject's body at an associated acquisition time. A frame time is determined for each frame, each frame time being the time from the preceding trigger signal to the acquisition time for the frame. Two or more frame series are then played back in order of increasing frame times, thereby producing a display frame rate higher than the acquisition frame rate.
