一种用于开放式 MRI 的射频发射线圈设计
A RF Transmit Coil Designed for Open Magnetic Resonance Imaging
摘要
Abstract
The design of a radiofrequency (RF) transmit coil for open magnetic resonance imaging (MRI) was introduced. The transmit coil is consisted of two rectangular solenoid coils with the same size which are installed on the two poles of the magnet in orthogonal directions. The two coils are positioned. A transmit coil used for 0. 23 T open MRI was made. Numerical simulation of electromagnetic fields was used to optimize the distance of the turns in the coils. The homogeneity and power efficiency of the coil were measured experimentally. The deviation of the amplitude of the RF field in a sphere of 300 mm in diameter was measured to be less than 3 dB.关键词
