[Investigations on hips and extremities by ultrasonics (author's transl)].

Using a Picker Echoview System 80 L, an Ultrasound Compound scanning instrument from Picker Roentgen GmbH, Espelkamp, Germany, some investigations on bones and joints were performed. In comparison with needle probe diameter measuring of muscles it could be shown that ultrasound tomography gives identical results without pain. Figuring of hip and knee joints outlines was possible. Alterations of muscles and tendon tissue were to be seen. Special meridians on the hip joint, along with the ultrasound probe had to be moved, were defined by anatomical marking points. So it became possible to reproduce some angles which usually had to be measured at X-ray pictures.
