Abstract

Based on the requirements of test protocols developed to evaluate clinical MRS single slice and volume localisation sequences, two clinical test objects, STO1 and STO2 have been developed. The properties of a range of potential construction materials have been assessed, demonstrating that the water/Perspex interface produced minimum susceptibility effects. The design of the objects has been evaluated in trials on different magnetic resonance instruments, with size and loading being adjusted to allow use on currently available equipment. Appropriate test solutions for 31P and 1H measurements have been developed and their properties evaluated.

摘要

根据为评估临床磁共振波谱（MRS）单层面和容积定位序列而制定的测试协议要求，已开发出两个临床测试对象STO1和STO2。已评估了一系列潜在建筑材料的特性，结果表明水/有机玻璃界面产生的磁化率效应最小。已在不同的磁共振仪器上进行的试验中对这些对象的设计进行了评估，并对尺寸和负载进行了调整，以便能在现有设备上使用。已开发出适用于31P和1H测量的测试溶液，并对其特性进行了评估。
