基于自动计算和线上分析的磁共振成像质量控制系统的研究
The research of MRI quality control system based on automatic calculation and online analysis
摘要
Abstract
Objective:To explore the methods of automatic quality control of magnetic resonance imaging (MRI), and research the system of detection and control which can provide online assessment report of quality control about results of axis and landscape orientation. Methods: As the testing standards of MRI, the software system that included of client platform and remote online platform was constructed by using MATLAB and C++. The client platform used morphological algorithm, picture segmentation and pattern recognition technique to achieve automatic calculation for 13 kinds of quality control parameters of picture, such as signal-noise ratio, contrast ratio and so on, which obtained from quality control phantom of MRI. The remote online platform saved and uploaded test report through used the format of MySQL database, and it was built on the basis of online big data platform that included local machine, same model machine and the same kind of machine (monthly test and annual test). And then, the quality control report of online assessment was automatically generated after results of axis and landscape orientation was compared.Results:After the system was verified by actual quality control of 50 MRI from various area, model and category, the accuracy testing and assessment reports were obtained. And the system could implement routine automatic calculation and report generation of 13 quality control parameters, and its operation was stable and reliable.Conclusion: The software system, which was designed and applied to automatically calculate image quality and carry out assessment of quality control, can provide a reliable tool for testing stability of long and short term for quality control of MRI.关键词
