摘　　要：本文根据对全市二级医院15台磁共振仪的质量检测结果,从磁共振图像的信噪比、均匀度、层厚、高对比度空间分辨率、几何畸变率和鬼影等主要成像参数的评估指标来研究磁共振质量控制方案,从而提高对磁共振设备周期性检测的实践水平。This paper researched the quality control program for magnetic resonance imaging（MRI） based on results of quality testing of fifteen magnetic resonance imaging systems in the secondary hospitals in Shanghai. Evaluation indexes of imaging parameters used in the research included signal to noise ratio, image uniformity, slice thickness, high contrast spatial resolution, geometric distortion, and ghosting artifact. The research aimed to enhance the understanding and practice level in the periodic inspection of magnetic resonance equipment.
