摘要： Provided is a bone inspecting system for placing the lower legs (L) of an examinee (P) on a proximal support block (26) and a distal support block (28) mounted on a turning base (24). The proximal support block supports the heads of fibula, and the distal support block supports the lateral malleolus or medial malleolus of a tibial distal end of the examinee. The turning base is supported turnably on a turning axis positioned near the knees of the examinee, with respect to a main base (22), and is moved up and down by an elevating mechanism (30) disposed near the ankles. The turning base (24) is turned by the elevating mechanism while bearing the lower legs thereon, thereby positioning the lower legs horizontally.

摘要： An acoustic matching device has a water bag (64) that contains water and a water bag support frame (66) that sandwiches and supports the water bag on the left and right sides of the knee and curves along the knee cap. The water bag becomes a plate shape curved along the shape of the water bag support frame, which touches the knee cap and fits the unevenness of the knee. When an ultrasonic probe is moved along the knee cap, the acoustic matching between the knee cap and the ultrasonic probe is obtained.

摘要： A mounting unit (16) is aligned by using a mounting unit frame (58) touching the thigh and a knee-contacting portion (62) touching the knee, with the knee being bent. The mounting unit is also equipped with a probe support frame (60) used for moving an ultrasonic probe along the knee cap. The probe support frame moves rotationally about the mechanical center of the knee joint, thereby allowing the ultrasonic probe (78) to move along the knee cap while facing toward the mechanical center of the knee joint and to perform scanning of an ultrasonic beam.

摘要： An ultrasonic beam (40) for echo tracking is formed for a healthy portion (52a) of a bone (50) containing healthy portions (52a, 52b) and a fractured portion (54). Echo tracking processing is executed over the state where a load F is not applied to the bone (50) and the state where the load F is applied to the bone (50) so as to calculate a distortion amount of the bone (50) accompanying the load F via the ultrasonic beam (40) formed for the healthy portion (52a). The state of union of the fractured portion (54) is evaluated in accordance with the distortion amount obtained via the healthy portion (52a).

摘要： An echo tracking processor unit detects a bone surface section based on an echo signal and tracks a position of the bone surface section. An interpolation line generator unit generates an interpolation line connecting tracking points which represent the tracked bone surface section. A translational displacement corrector unit removes a translational displacement component between an interpolation line corresponding to a time phase of a no-load state stored in a memory and an interpolation line corresponding to a time phase in a loaded state output from the interpolation line generator unit. A strain calculator unit calculates an amount of strain of bone for each time phase and outputs to a characteristic curve generator unit. The characteristic curve generator unit generates a characteristic curve related to the strain of bone based on a load value output from a load measurement device and the amount of strain of bone output from the strain calculator unit.
