Abstract:
1. An ultrasonic bone analyzing device, comprising: a transmission module including a transducer that transmits an ultrasonic signal inside a living body from an outer skin of the living body; a reception module that receives with the transducer an echo signal that is a reflection wave of the transmitted ultrasonic signal from the inside of the living body; and an analyzing module including a processor that generates analysis data indicative of a state of a cartilage using an amplitude value of an echo signal from the inside of the cartilage obtained from between a cartilage surface and a subchondral bone among the received echo signals, wherein the transmission module is configured to transmit an ultrasonic signal at a predetermined frequency, the reception module is configured to receive the echo signal including two or more frequency components including the predetermined frequency and a second harmonic frequency of the predetermined frequency; and wherein the analysis data is generated based on a value reflecting a relative ratio between an integral value of the amplitude value of the echo signals from inside the cartilage and an integral value of the amplitude value of the echo signals from the cartilage surface.
