基于ACR标准的MRI图像均匀度及层厚的检测
The detection of image uniformity and slice thickness of MRI system based on ACR ;standards
摘要
Abstract
Objective:To detect the image uniformity and slice thickness of Siemens Skyra 3.0 T and GE Excite HD 1.5 TMRI system based on ACR standards. Methods:Image uniformity and slice thickness of MRI were measured with ACR phantom, and the detection results were calculated. Results: The image uniformity were 96.0% and 92.7% of Siemens Skyra 3.0T and GE Excite HD 1.5T MRI respectively, the slice thickness were 4.64 mm and 5.58 mm, the thickness deviation is 0.36 mm and 0.58 mm, then the results measured in the research were in the normal range. Conclusion: The detection of image uniformity and slice thickness can effectively guarantee the image quality and the accuracy of slice thickness.关键词
