TWO-DIMENSIONAL DOPPLER ULTRASONIC DIAGNOSIS DEVICE

摘要

PROBLEM TO BE SOLVED: To clearly express even relatively narrow blood flow. ;SOLUTION: A two-dimension Dopper ultrasonic diagnosis device is provided with scan means 2, 3 to scan a cross sectional surface of a sample by an ultrasonic beam, and a blood information operating part 5 to measure speed data for multiple points in the cross sectional surface based on ultrasonic echo obtained by the scan means 2, 3. It is also provided with an interpolation means to apply interpolation to speed data for a point which is not actually measured based on the speed data for plural actually measured points close to it, and an interpolation function. In addition, it is provided with a comparator to compare the speed data for the respective close points with a threshold value, and a changing means to change the interpolation function based on result of comparison by the comparator.;COPYRIGHT: (C)1997,JPO
