Method and the device which detect the blood speckle with the ultrasonic image formation system inside the blood vessel

摘要

(57) Abstract The speckle of the blood is detected method and the device of image forming inside the blood vessel which is improved. As for this invention, as for energy dispersion strength from blood, the high frequency dependancy is shown, but dispersion strength from organization, utilizes the fact there is no strong frequency dependancy. With execution example of specification, as for this invention, especially, the blood dispersion strength of organization has close dispersion strength, in the circumstance where and/or the blood moves slowly, or does not move completely, problem of the blood speckle in ultrasonic image forming inside the blood vessel is handled, especially being simple, it offers useful solution.
