  • Bone inspecting system, and lower leg supporting device
    Patent number: 8317710
    Abstract: 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.

  • ULTRASONIC DIAGNOSIS APPARATUS
    Publication number: 20110224545
    Abstract: 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).
