Implantable medical equipment electromagnetic model transfer function verification system and method based on four-way parallel transmission

Abstract

The invention provides an implantable medical device electromagnetic model transfer function verification system and method based on four-way parallel transmission. According to response characteristics of an implantable medical device in a radio frequency field, the implantable medical device electromagnetic model transfer function verification method is provided. Resonance electric fields with different circular polarization characteristics are generated based on four parallel transmission lines to replace a traditional birdcage radio frequency coil and an electric field generator based on a cavity resonator, and complete verification of the radio frequency heating transfer function of the implantable medical device is achieved. According to the system, the defects that a birdcage coil is large in occupied area, prone to electromagnetic interference and high in manufacturing cost are overcome, meanwhile, the defect that a cavity resonator can only generate a single polarization electric field is overcome, and therefore the uncertainty of verification testing is reduced; and a solution is provided for realizing rapid and effective radio frequency heating transfer function verification.

Description

Technical field [0001] The present invention belongs to the field of image detection, involving an electromagnetic model transfer function verification system and method for implantable medical equipment based on four parallel transmission. Background technique [0002] In recent years, with the rapid development of bio-electronic technology, implantable medical equipment has been an indispensable part of the monitoring of human health indicators, the treatment of diseases and the repair of human function. Since the metal part of the implantable medical device is very sensitive to external electromagnetic fields, it is easy to afford electromagnetic field interference to generate some difficult predictions, and therefore, it is usually worn by an implantable medical device. It is not allowed to enter an environment in which complex electromagnetic fields exist. This greatly limits the application scenarios of these implantable medical devices, especially when patients need other ...
