Abstract
To accurately detect a shape and derive information of cartilage based on detected echoes, an ultrasonic diagnosing device includes an ultrasonic transmitter, an ultrasonic receiver, a low-frequency component extracting module, and a deriving module. The ultrasonic transmitter transmits ultrasonic waves to a cartilage in a plurality of bent states, in a state where a relative position of a wave transmitting and receiving surface to the cartilage is fixed. The ultrasonic receiver receives echo signals corresponding to respective frames in each of the plurality of bent states. The low-frequency component extracting module extracts, in a frame direction, low-frequency echo data which is echo data of a frequency component below a given frequency. The deriving module derives information of the cartilage based on the low-frequency echo data.
