研究人员感兴趣的是了解截肢者的幻肢痛(PLP)和残肢痛(RLP)及其导致的神经机制。功能磁共振成像可以提供大脑中控制PLP和RLP的激活中心的强度和位置的信息。MR安全测痛仪对这项工作很重要。本文介绍了一种新型气动测痛仪及其安全性评价方法。我们的结果表明，定制的装置是一种改进的MR安全测压仪，能够自动产生可重现的压力分布。
Researchers are interested in understanding phantom limb pain (PLP) and residual limb pain (RLP) in amputees and the neural mechanisms leading to it. fMRI can provide information on the intensity and the location of activated centers in the brain that control PLP and RLP. MR safe algometers are important to this work. This paper described the new pneumatically actuated algometer and the evaluation methods for MR safety. Our results indicate that the custom device is an improved MR safe algometer capable of autonomously producing reproducible pressure profiles.
