The invention discloses a knee joint dynamic imaging device and an application method thereof. The knee joint dynamic imaging device comprises a cyclic loading assembly, a magnetic resonance scanner and a data terminal, wherein the cyclic loading assembly comprises a cylinder and a hospital bed; the cylinder is in transmission connection with a push rod; the push rod is connected with a foot sleeve; a thigh binding band, a shank binding band and a fixing fixture are arranged on the top surface of the hospital bed; a pressure sensor is arranged between the push rod and the foot sleeve; a displacement sensor is arranged between the cylinder and the foot sleeve; the data terminal is in signal connection with the pressure sensor, the displacement sensor, the cylinder and the magnetic resonancescanner; and the data terminal comprises an I / O device, an electronic clock, a processing center and a counter. The knee joint dynamic imaging device disclosed by the invention can perform imaging operation on joints under a load state, so that influence of other phases on images is effectively reduced, the structure is simple, and the cost is low.
Description
technical field [0001] The invention relates to the field of medical imaging devices, in particular to a knee joint dynamic imaging device and an application method thereof. Background technique [0002] In the clinical diagnosis of bone and joint, there is a very important inspection content, that is, to detect the joint shape and intra-articular structure under load, so as to analyze the development and pathological state of bone and joint lesions. As we all know, there are differences in the shape of the menisci and ligaments of the large joints of the human body under load and non-load conditions. Joint imaging examinations and physical examinations under the non-load state cannot reveal the structural changes and relative position changes in the joints when people are walking or standing upright. . Therefore, in orthopedics and imaging examinations, weight-bearing X-ray joint photography has become a commonly used examination method, and it is also one of the standard ...
