Abstract
An image processing device (8) includes: a frequency analysis section (12) for detecting an amplitude frame (PA) of a specific frequency component and a phase frame (PP) of the specific frequency component by performing a frequency analysis of time-series changes p.sub.x,y(t.sub.i) in echo intensity frame (p.sub.x,y) or time-series changes q.sub.x,y(t.sub.i) in Doppler velocity frame (q.sub.x,y) at various points within a cross-section of a specimen, the echo intensity frame (p.sub.x,y) and the Doppler velocity frame (q.sub.x,y) being each obtained by scanning the cross-section of the specimen with an ultrasonic beam; and an image generation section (13) for generating a two-dimensional image based on the amplitude of the specific frequency component and the phase of the specific frequency component thus detected. Thus, an image processing device can be provided which makes it possible to observe a two-dimensional shape of a specimen, the intensity of a periodic motion of the specimen, and spatial continuity in phase of the periodic motion of the specimen.
