Title: Ultrasonic image display method and ultrasonic diagnostic equipment
Inventor: SUZUKI YOICHI
IPC: G01S7/52
Filed: 2001-05-07
Abstract: PROBLEM TO BE SOLVED: To suppress blooming wherein a blood vessel protrudes outside an actual vessel wall in color Doppler display of an ultrasonic diagnostic device and is depicted as a thick blood vessel, and to prevent reduction of depiction power of a thin blood vessel. SOLUTION: Basically, when power P is increased, a luminance is increased. When two sampling points having the same power P and different variances V are present in an area wherein the power P is small (P<=P1), the luminance of a pixel corresponding to a sampling point having the variance V relatively larger than the luminance of a pixel corresponding to a sampling point having the relatively smaller variance V is increased. Thereby, by largely reducing a gain when increasing the power P by injecting a contrast medium, the blooming can be suppressed. When the contrast medium is injected, the variance V increases. Accordingly, the luminance of the sampling point having the relative large variance V is increased and becomes a large value. As a result, the depiction power of the thin blood vessel is increased.  That is, the blooming can be suppressed, and the reduction of the depiction power of the thin blood vessel can be prevented.
