Abstract

The embodiment of the invention provides a safety prompting system and method for an implanting device in a MR imaging system. The safety prompting system comprises an indicating device which is usedfor expressing the position relationship between the implanting device of an object to be detected and a safety border through indicating the predetermined safety border, wherein the position range limited by the safety border is located in a column-shaped space region allowing the implanting device to enter, in a main magnet field space gradient intensity distribution region of the MR imaging system.

Description

technical field [0001] The present invention relates to the field of medical detection, in particular to a safety prompt system and method for an implant device in an MR imaging system, and a computer-readable storage medium. Background technique [0002] Before using Magnetic Resonance (MR) imaging technology to image the human body, a safety assessment is required for implanted devices in the human body, such as cardiac pacemakers, orthopedic implants, and puncture equipment, because such devices May pose safety concerns during MRI procedures. To avoid such problems, some hospitals have regulations prohibiting MR examinations on patients with implanted devices or certain types of implanted devices. [0003] In recent years, more and more people choose to implant medical, orthopedic, orthopedic devices in the body. It is predicted that in 2020, the number of patients with implanted devices in the body will increase by 71%. Therefore, for implanted devices Restrictions wil...
