一种相控阵线圈被开发，以方便成像的血管系统的下肢。该阵列由四个表面线圈组成，放置在一个有机玻璃“I - beam”框架中，配置为允许双边研究，视野高达40厘米（FOV）。来自幻像的数据表明，感兴趣区域的信噪比（SNR）比体线圈的信噪比平均增加了2.8±0.9倍。从n= 8个受试者中也获得了初步的活体数据，并显示出图像质量的显着改善。这里描述的线圈设计应该可以减少扫描时间，因为它能够同时对两条腿进行成像，减少患者重新定位的需要。
A phased‐array coil was developed to facilitate imaging the vasculature of the lower extremities. The array consists of four surface coils placed in a Plexiglas “I‐beam” frame that are configured to allow bilateral studies with up to a 40‐cm field of view (FOV). Data from phantoms indicate an increase in signal‐to‐noise ratio (SNR) in the regions of interest by an average factor of 2.8 ± 0.9 over that of the body coil. Preliminaryin vivodata have also been obtained fromn= 8 subjects and demonstrate significant improvements in image quality. The coil design described here should lead to reduced scan times through the ability to image both legs simultaneously with less need for patient repositioning.
