Ultrasonic body tissue detection device, ultrasonic body tissue detection method, and ultrasonic body tissue detection program

摘要

It is an object to detect a body tissue to be detected with high accuracy, reliability and automatic. The ultrasonic body tissue detection device (10) includes a transmission / reception unit (11), a two-dimensional data acquisition unit (14), a spatial frequency distribution calculation unit (15), and a determination unit (16). The transmission / reception unit (11) transmits an ultrasonic signal into the body of the specimen and receives the echo signal. The two-dimensional data acquisition unit (14) forms a two-dimensional echo image having two dimensions in the ultrasonic transmission direction and the scanning direction. The spatial frequency distribution calculation unit (15) calculates a spatial frequency distribution for the determination target position by performing frequency conversion on the two-dimensional echo image. The determination unit (16) determines whether the determination target position is a body tissue to be detected based on the amplitude distribution along the ultrasonic transmission direction of the spatial frequency distribution and the amplitude distribution along the scanning direction.
