Abstract:
1. A bone strength diagnostic device, comprising: a wave-transmission module for deriving a speed of sound that transmits an ultrasonic wave from a wave-transmission transducer for deriving the speed of sound obliquely to a bone covered with soft tissues; a wave-reception module for deriving the speed of sound that receives the ultrasonic wave that exits from the bone to the side of the soft tissues with a plurality of wave-reception transducers for deriving the speed of sound, the ultrasonic wave being received after it is transmitted from the wave-transmission module for deriving the speed of sound and propagates along a front surface of the bone; a shape detection module for detecting a shape of the front surface of the bone; and a speed-of-sound deriving module for deriving the speed of sound of the ultrasonic wave that propagates along the front surface of the bone based on the received wave signal by the wave-reception module for deriving the speed of sound, and the shape of the front surface of the bone detected by the shape detection module, wherein the shape detection module includes: wherein the wave-transmission module for shape detection includes a plurality of wave-transmission transducers for shape detection that transmit the ultrasonic waves simultaneously; and wherein the wave-reception module for shape detection includes a plurality of wave-reception transducers for shape detection that receive the front-surface reflected wave; and wherein the front surface shape detecting module includes:
