    摘要: A system and method for determining bone characteristic data is provided. The system combines a biochemical bone measuring unit with a densitometric bone measuring unit to determine the bone characteristic data. Once the bone characteristic data is ascertained, a determination of whether bone formation or bone resorption is occurring is made and future bone characteristics can be projected.

    摘要: A method of calibrating an ultrasound bone analysis apparatus having a pair of transducer assemblies. Each transducer assembly has a transducer and a coupling pad, and is movable relative to the other so that a face of each pad can be moved to a position in which they mutually contact and to a position where the faces contact body parts. The method according to the present application includes transmitting an ultrasound signal from one transducer and receiving a signal corresponding to the transmitted ultrasound signal through the other transducer when the transducer assemblies are in the first position and the second position. A time for the ultrasound signal to pass through the body part is determined, and a width of the body part based on positions of the transducers is determined. Then, using the time and width values a speed of sound of the ultrasound signal passing through the body part with squish compensation is calculated.

    摘要: An ultrasonic bone testing apparatus has a foot well assembly and a shin guide assembly which are mechanically coupled to secure a foot and lower leg of patient. The shin guide assembly includes a molded form lined with contoured foam lining. An instep support guide having sliding blocks is mounted on the molded form. The sliding blocks attach the shin guide assembly to the foot well assembly. The apparatus further includes a transducer drive mechanism for positioning a pair of transducer assemblies. A controller automatically modifies the positioning of the transducer assemblies until ultrasonic coupling is achieved and a receiving transducer receives a signal of a predetermined quality. The distance between the transducers is continuously measured by a position encoder. The controller uses temperature readings from a temperature sensor to improve the accuracy of the position encoder measurements and correct for temperature dependent inaccuracy in the ultrasound measurement. A coupling pad and acoustical delay line of the transducer assembly provide a waveguide function to collimate an acoustical beam. The elastomer coupling pad has an angled surface which expels air bubbles from a contact area when pressure is applied to the pad.
