The bone roughly the pore symptom progress instrument and the bone it is rough pore symptom progress measurement method

摘要

It is twisted the suffering body (200) vis-a-vis the bone section and the ultra wave which relates to the being twisted vibration which the ultrasonic oscillation section (110) from oscillates, the suffering body (200) the bone section is spread, the suffering body (200) through, the ultrasonic sensing station (120) with it detects the ultra wave which gives the vibration, particular ultrasonic damping coefficient (it calculates attenuation factor) and speed of sound on the basis of the ultra wave which relates to the being twisted vibration which is detected particularly CPU (150) in, on the basis of damping coefficient and the speed of sound which were calculated the suffering body (200) the bone in the bone section it is rough advance of the pore symptomThe quality which displays circumstance (bone age) try to calculate. Because of this, there are no times when great load is applied on the body of the subject, the bone are rough progress of the pore symptom quantitatively, at the same time, try to be able measure properly.
