Muscle area measuring equipment carried by magnetic resonance imaging scanner

Abstract

The invention discloses muscle area measuring equipment carried by a magnetic resonance imaging scanner. The equipment comprises a base, upright plates are arranged on the left and right sides of theupper end surface of the base, and a first coupler is arranged at the left lower end of the middle of the upright plate on the left side; a stepping motor is arranged on the left side of the first coupler, a rotary shaft is arranged on the lower side between the two upright plates, and a gear is arranged in the middle of the rotary shaft; an output shaft of the stepping motor is connected with therotary shaft through the first coupler, a lead screw and a guide rod which are parallel are arranged on the upper side between the two upright plates, and a moving block is arranged on the lead screw. The equipment is simple in structure and convenient to use, the muscle of a patient can be measured from different angles to achieve multi-angle measuring on the muscle, a user can more comprehensively know the structure of the muscle, the limb of an abnormal patient can be fixed, it is avoided that bad influences on the measuring are caused by the abnormal patient, so that the measuring resultis influenced, and the accuracy of the measuring result of the muscle area is ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a muscle area measuring device mounted on an nuclear magnetic resonance scanner. Background technique [0002] Different tissues of the human body allow different long-wave components generated by magnetic resonance, such as radio waves, to pass through, which is the basic principle of the work of nuclear magnetic resonance scanners. In modern medicine, various basic parameters of the patient's musculoskeletal system are often tested, such as muscle area, and then determine whether the patient's musculoskeletal system is pathological, but there are some defects in the existing measurement equipment, because the human muscle is a three-dimensional shape, it is necessary to measure the muscle area of ​​the human body from different angles At the same time, during the measurement process, for some patients who are mentally abnormal or active, it is necessary to fix the patie...

In modern medicine, various basic parameters of the patient's musculoskeletal system are often tested, such as muscle area, and then determine whether the patient's musculoskeletal system is pathological, but there are some defects in the existing measurement equipment, because the human muscle is a three-dimensional shape, it is necessary to measure the muscle area of ​​the human body from different angles At the same time, during the measurement process, for some patients who are mentally abnormal or active, it is necessary to fix the patient's body, so as to avoid the inconvenience that the patient's movement may bring to the measurement.
