Abstract

The invention discloses a human body bone joint kinematics dynamic collection system. A Y-axis movable base is arranged on an X-axis movable base. A Z-axis supporting frame is arranged on the Y-axis movable base. A human body supporting pedal is independently arranged on the ground. A rotating shaft is arranged on the Z-axis supporting frame. A first supporting frame and a second supporting frame are arranged on the rotating shaft. A first X-ray tube and a first X-ray receiver are arranged on the first supporting frame. A second X-ray tube and a second X-ray receiver are arranged on the second supporting frame. A motion capture device is arranged on an object to be collected. A motion collection device is arranged on the rotating shaft. A computer controller is independently arranged. Relative rest of the motion capture device and the motion collection device can be ensured, and it is ensured that the focal lengths of the X-ray tubes and the X-ray receivers will not change. The best radiation effect is ensured by adjusting the irradiation angle, and the device is simple in structure and can rapidly and accurately collect human body bone joint in-vivo kinematics.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a dynamic acquisition system for human bone joint kinematics. Background technique [0002] The occurrence and development of bone and joint injuries and diseases are often accompanied by changes in local joint motion characteristics. At the same time, some abnormal joint activities can also lead to diseases. Detecting the kinematic characteristics of the bone and joint system in vivo is of great significance to the scientific research, diagnosis, treatment and prognosis evaluation of diseases. [0003] Optical motion capture and motion sensing are currently widely used kinematic detection methods. However, in these methods, optical markers or physical sensors that capture motion are installed on the surface of the limbs. Due to the large relative movement between the skin and bony structures, the limb movement information obtained by the above methods is no...
