Abstract

Magnetic resonance angiography of the peripheral vascular system has been hampered by the limited view provided by available imaging coils. We have constructed an extended-length, split-saddle design radiofrequency (rf) coil for peripheral angiography. The two coil halves are inductively coupled, to each other and to the rf source. Details regarding the construction of the coil and comparison of the performance with the knee coil are described here. This coil provides the benefit of a larger field of view but with image quality comparable to that of a commercial knee coil.

摘要

外周血管系统的磁共振血管造影一直受到现有成像线圈所提供有限视野的限制。我们构建了一种用于外周血管造影的延长长度、分体鞍形设计的射频（rf）线圈。线圈的两个半部相互之间以及与射频源进行电感耦合。本文描述了该线圈的构建细节以及与膝关节线圈性能的比较。这种线圈具有更大视野的优势，但其图像质量与商用膝关节线圈相当。
