摘要
磁屏蔽室(MSR)是测量磁心动图(MCG)和脑磁图(MEG)的必要设备之一。传统的封闭式磁屏蔽室只关注屏蔽磁场的指标,而忽略了患者在磁屏蔽室内的感受。本文提出了一种开窗式 MSR,以解决患者在封闭式 MSR 中难以与外界交流、产生封闭恐惧的问题。仿真结果表明,带屏蔽导管和主动磁补偿线圈的 MSR 内部工作区残余磁场的大小和分布趋势与封闭式 MSR 相似。本文提出的方法为提高患者在 MSR 中测量 MCG 和 MEG 的舒适度提供了一种途径。
Open-window MSR Design with Active Magnetic Compensation Coil based on COMSOL Multiphysics.
Magnetic shielding room (MSR) is one of the necessary equipment for measuring magnetocardiography (MCG) and magnetoencephalography (MEG). The traditional closed MSR only focuses on the indicators of the shielded magnetic field, and ignores the patient's feelings within the MSR. In this paper, an open-window MSR is proposed to solve the problem that patients have difficulty in communicating with the outside of closed MSR and have closed fear. The simulation results show that the size and distribution trend of the residual magnetic field in the inner working area of the MSR with shield-duct and active magnetic compensation coil is similar to that of the closed MSR. The method proposed in this paper provides a way to improve the comfort of patients in MSR for measuring MCG and MEG in humans.
期刊介绍:
BPEX is an inclusive, international, multidisciplinary journal devoted to publishing new research on any application of physics and/or engineering in medicine and/or biology. Characterized by a broad geographical coverage and a fast-track peer-review process, relevant topics include all aspects of biophysics, medical physics and biomedical engineering. Papers that are almost entirely clinical or biological in their focus are not suitable. The journal has an emphasis on publishing interdisciplinary work and bringing research fields together, encompassing experimental, theoretical and computational work.
