ULTRASONIC DIAGNOSTIC APPARATUS AND ULTRASONIC IMAGE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus and an ultrasonic image processing program each capable of reducing clutters and/or motion artifacts.SOLUTION: An ultrasonic diagnostic apparatus 1 includes a tomographic image data generation unit 13, a blood flow information generation unit 14, a variation detection unit 15 and a condition change unit 16. The tomographic image data generation unit 13 sequentially acquires tomographic image data of a subject with respect to a plurality of periods of time. The blood flow information generation unit 14 subjects reception signals to a processing based on a signal processing condition including a rate threshold value related to the blood flow information on the subject to acquire the blood flow information. The variation detection unit 15 receives a plurality of tomographic image data different in a period of time from each other and detects the magnitude of the change in a time base direction. The condition change unit 16 changes the signal processing condition on the basis of the magnitude of the change in the time base direction detected by the variation detection unit. When the condition change unit 16 changes the signal processing condition, the blood flow information generation unit 14 acquires the blood flow information by subjecting the received signals to a processing based on the changed signal processing condition.
