Research on Imaging Quality Evaluation Model of MR Equipment Based on Fuzzy Set Theory
摘要
Abstract
Objective To evaluate the imaging quality of magnetic resonance imaging equipment and monitor the trend of imaging quality to ensure the quality of clinical diagnostic images. Methods The fuzzy set theory was introduced into the imaging performance analysis of magnetic resonance imaging equipment. By analyzing the image quality comprehensive evaluation index data of magnetic resonance imaging equipment, a multi-parameter MRI image quality grade evaluation model was established. Results With magnetic resonance equipment in our hospital as the research object, using the test parameters, a period of time before and after the after-sale service' maintenance, for the test sample to verify this model, the model analysis results were consistent with practical experience. Conclusion The evaluation model of multi-parameter parameters established in this paper can effectively evaluate the image quality level of magnetic resonance equipment, and strengthen the connection with clinical diagnostic images. The establishment of the image quality factor trend chart, help to develop the optimal equipment maintenance plan to protect the equipment in a safe, accurate and effective working condition.关键词
