Patent ID: 11259779

Abstract:
A body tissue to be detected is automatically detected certainly with high precision. An ultrasonic body tissue detecting device may include a transmission/reception unit, a two-dimensional data acquisition unit, a spatial frequency distribution calculation unit and a determination unit. The transmission/reception unit may transmit an ultrasonic signal into a body of a sample and receive an echo signal of the ultrasonic signal. The two-dimensional data acquisition unit may form two-dimensional echo image in a transmitting direction of the ultrasonic signal and in a scanning direction. The spatial frequency distribution calculation unit may perform a spatial frequency conversion of the two-dimensional echo image and calculate a spatial frequency distribution for a determining position. The determination unit may determine whether the determining position is the body tissue to be detected based on a distribution of amplitude in the transmitting direction of the ultrasonic signal and a distribution of amplitude in the scanning direction of the spatial frequency distribution.
