PROBLEM TO BE SOLVED: To estimate automatically a Doppler angle by carrying out an optimal initial point detection and the most reliable pixel point search, using an algorithm, and an automatic blood vessel gradient measuremently using B mode strength data or the like. SOLUTION: A host computer freezes automatically an image and performs the reading 40 of frames of B mode image data and color flow image data. Subsequently, by executing an algorithm, a search area central point identification 42 is executed. A judgment 44 is made as to whether a pixel address to a central point position is included or not. If the pixel address is included, a blood vessel gradient measurement 50 is carried out by linear fitting through a color flow edge point decision 46, and the grouping 48 of edge points. A Doppler angle computation 62 is executed in processes following the B mode edge determination process 52. This method can provide automatically Doppler angle computation. |
