NMR Simulation Positioning Machine Quality Control, Quality Assurance Research And Data Analysis

Purpose The aim of this study is to establishment the quality control process and analyze the quality control data for MR simulator.Methods A single center study was conducted in PUMCH.The quality control processes of daily,monthly and annually quality assurance(QA)were designed.The 147 times of daily QA(from May 2019 to Sep.2020),18 times of monthly QA(from July 2019 to Dec.2020),1 time of annually QA(2020)were collected and conducted by descriptive statistical analysis.Results The data of 147 times of daily QA,18 times of monthly QA,1 time of annually QA all met the acquirements for TG66,TG100,the verification regulation of CT simulation and ACR reports in the aspects of equipment status,magnet performance,safety project inspection,special coil connection,mechanical accuracy and image quality.Conclusions Establishing and proficiently operating the processes and methods of quality control,and regularly inspecting the equipment status is an important guarantee to ensure the long-term,high-speed and stable operation for MR simulator.
