| 20100018313 | METHOD AND DEVICE OF DETECTING SHAPE AND BONE STRENGTH DIAGNOSTIC DEVICE USING THE DEVICE - The disclosed device includes a module for transmitting an ultrasonic wave from a transducer to an object, another module for receiving with transducers surface waves that are a reflection of the ultrasonic wave on the object surface, another module for detecting an incoming direction of the reflected wave to each transducer group using a time difference between reception timings of two reception transducers constituting each group, each group having two transducers adjacent to each other, another module for detecting a propagation time of the surface wave reached each group using a received wave signal of the surface wave of at least one of the reception transducers, another module for detecting a reflection point of the ultrasonic wave on the object surface based on the incoming direction and the propagation time of the surface wave detected for each group, and another module for deriving a shape of the object surface using the reflection points for the transducer groups. | 01-28-2010 |
| 20100030080 | METHOD AND DEVICE OF DIAGNOSING BONE STRENGTH - A bone strength diagnostic device includes 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, with a plurality of wave-reception transducers for deriving the speed of sound, the ultrasonic wave that exits from the bone to the side of the soft tissues, the ultrasonic wave being received after it is transmitted from the wave-transmission module for deriving the speed of sound and propagating along a front surface of the bone; a shape detection module for detecting the 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 signals, using the wave-reception module for deriving the speed of sound, and the shape of the front surface of the bone detected using the shape detection module. | 02-04-2010 |
| 20100257935 | METHOD AND APPARATUS FOR MEASURING SPEED-OF-SOUND - A speed-of-sound measurement apparatus includes a wave transmission module for transmitting an ultrasonic wave to a front surface of a subject's body, a plurality of wave reception modules which each receives the ultrasonic wave from the subject's body and outputs a waveform signal corresponding to the received ultrasonic wave, a presumed propagation time calculating module for calculating a propagation time from when the ultrasonic wave is transmitted by the wave transmission module to when the ultrasonic wave arrives at each of the wave reception modules after propagating along the front surface of the subject's body or inside the subject's body, based on a presumed value of speed-of-sound in the subject's body and a front surface shape of the subject's body, a validity index value calculating module for finding a validity index value to be an index of validity of the propagation time based on the waveform signals outputted by at least two of the plurality of wave reception modules, and a speed-of-sound deriving module for finding the speed-of-sound in the subject's body based on the validity index value. | 10-14-2010 |
