摘要
为进一步提高表面线圈在MR成像中的应用价值,通过对几种不同规格的线圈在标准模型上成像效果的检测,并就如何合理选择表面线圈的有关问题作了初步探讨。认为,不同机型中各类表面线圈均可根据信噪比──深度曲线以及充分权衡线圈大小、受检部位大小和深度三者间关系,制定出一套适合于各自选择表面线圈的应用规范,以确保MR成像质量。
To improve the application value of surface coil in MRI, the imaging effects of surface coilswith different gauge on standard model was measured, and primarily investigated the problem on how toproperly select surface coil. It is showed that, a set of value for each surface coil can be decided by the signalnoise ratio──depth curve and carefully banlancing of relationship among three factors, i. e, the size of sur face coil, the size of examined body part and the depth of the examined body part. Thus, the quality of MRIcan be assured.
