ULTRASONIC DIAGNOSTIC APPARATUS, METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic technology for quantifying the movement of the heart before and after applying a load to a patient and making a display of graphs to be compared on one screen.

SOLUTION: The ultrasonic diagnostic apparatus 10 includes: a probe 20 scanning ultrasonic waves U on a subject H who performs periodic motion, at intervals narrower than the period of the subject H, and detecting the reflected waves; an image forming section 46 processing the reflected waves to form a tomographic image D of the subject H on a scan surface S of the ultrasonic waves U; a region setting section 51 setting an interest region R on a part of the scan surface S; a quantifying section 52 outputting numerical data obtained by digitizing each interest region R in a plurality of tomographic images D; a graph generating section 53 generating a graph with numerical data points plotted in time series; and an extracted graph allocating section 66 displaying a first extracted graph extracting one period part from the graph and a second extracted graph extracting one period part of a time zone different from the first extracted graph.
