摘要
Abstract
Objective:To study the influence of different phantoms for measured result of MRI slice thickness, to study the influence of different methods of measurement on the measured result of MRI slice thickness. Methods:According to the standard,4 kinds of phantoms were developed and 2 kinds of methods were employed totes MRI slice thickness, the results were analyzed and compared to the results get by phantoms imported from USA. Results:The test results were gotten by Matlab, then the factors of influence which were mainly consensus with the theory were confirmed. Conclusion:The 4 kinds of phantoms can satisfied the requirement of MRI slice thickness testing, the slab method is more easy to operate then the wedge method, the results of slab method are more close to the results of SMR 170 phantom, the accuracy can be improved largely by applying the tilt correction.关键词
