Title:
超音波診断装置
Document Type and Number:
Japanese Patent JP4263943
Kind Code:
B2
Abstract:
An ultrasonic diagnostic system according to the present invention has an ultrasonic transducer(520) mounted on a catheter(510), an instantaneous distortion value calculator(420) which calculates an instantaneous distortion value at the location to be evaluated in the blood vessel based on received signal representative of received reflection by the ultrasonic transducer(520), an analyzer(430) which analyzes a state of the location to be evaluated using time-series data of instantaneous distortion values which are calculated at a plurality of times in a chronological sequence by the distortion value calculator(510), and a display(300) which displays an analyzed result produced by the analyzer(430).
