Abstract:
1. A data processing method for an ultrasonic diagnostic apparatus, the method comprising: a data extraction step for acquiring data corresponding to a same predetermined depth, out of a plurality of pieces of ultrasonic data acquired by ultrasonic transmission/reception means for acquiring the plurality of pieces of ultrasonic data by performing a plurality of times of ultrasonic transmitting/receiving operations in a same sound ray direction and at predetermined time intervals; a filtering step for inputting the data corresponding to the same predetermined depth, acquired in the data extraction step, into filters each having a predetermined characteristic, and extracting echo data from a moving part in a body; a first amplitude value calculating step for calculating a first autocorrelation amplitude value based on the echo data, when the echo data from the moving part in the body, acquired in the filtering step, is delayed by a first predetermined time period; a second amplitude value calculating step for calculating a second autocorrelation amplitude value based on the echo date, when the echo data from the moving part in the body, acquired in the filtering step, is delayed by a second predetermined time period; and a colorization step for relating an average value obtained by averaging, using an averaging processor, the first autocorrelation amplitude value by the second autocorrelation amplitude value, to the luminance of a predetermined hue.
