Problems solved by technology
However, CT equipment is very complicated and expensive, and it is not convenient for some patients with metal implants to measure more frequently during rehabilitation
Moreover, since CT imaging detection uses radiation technology, it will inevitably have a certain negative impact on the tested human body.

The invention relates to a human body metal implant detection device based on electromagnetic sensors. The device is used for detecting whether a human body metal implant is normal or not. The device comprises a sensor array arranged in a detection area, an excitation and detection receiving circuit connected with the sensor array through a circuit, and an upper computer connected with the excitation and detection receiving circuit through the circuit, wherein the detection area is used for placing a human part implanted with a metal implant, the sensor array includes a plurality of electromagnetic sensors distributed around the detection area, and the electromagnetic sensors are co-circular in the same plane. The invention further relates to a human body metal implant detection method based on electromagnetic sensors. On the premise that normal use of the metal implant is not affected, non-contact detection can be truly realized, abnormal conditions such as dislocation, falling off, deformation, chemical property change and the like of the metal implant in the human body can be judged rapidly, and the device and the method have the advantages of being convenient, fast, effective and reliable in detection.
Description
technical field [0001] The invention relates to a detection device and a detection method for a human body metal implant, in particular to a detection device and a detection method for a human body metal implant based on an electromagnetic sensor, and belongs to the technical field of electromagnetic sensing. Background technique [0002] In the field of modern medicine, human metal implants (such as steel nails, steel plates, etc.) have been widely used, especially in the treatment and rehabilitation of bone injuries. After the human body is implanted with a metal object, it is necessary to ensure the stability of the implanted position and chemical properties of the metal implant, and avoid some metal implants caused by irresistible factors such as displacement, falling off, deformation, and chemical property changes. question. Therefore, the first thing that needs to be solved is the detection problem of the metal implant. [0003] In the existing research results and p...
