摘要:
Provided is an ultrasonic imaging apparatus including: a time-gain controller (TGC) that compensates an amplitude fading occurring in the process of propagation inside a living body; a scan converter (SC) that constructs image data; a TIC measurement unit that measures a TIC of each pixel; an evaluation index input unit that inputs an index for evaluating hemodynamics on the basis of a TIC; a mapping parameter estimation unit that estimates a mapping parameter comparable to an evaluation index; a TIC image construction unit that constructs a two-dimensional image on the basis of the mapping parameter; and a pixel detection unit that extracts a region corresponding to a color map from a TIC image, and utilizing a TIC measured with each pixel so as to measure a difference in hemodynamics.
