Abstract
In response to heartbeat signals produced by an ECG adapted to detect heartbeats of a subject, an ROI (region of interest) of the subject is scanned plural times to produce a plurality of frames of Doppler image information. In this case, the starts of the scans of the ROI are sequentially delayed from corresponding heartbeat signals in increments of a regular time interval. Each frame of image information is stored in a frame memory in the form of divided sub-frame signals. Corresponding sub-frame signals of the frame signals are read from the frame memory and then synthesized to reconstruct one frame image.
