This paper presents an upgrade of a Phantom Premium 1.5 haptic device for use within a functional magnetic resonance imaging (fMRI) environment. A special mechanical extension that allows the haptic device to operate at a safe distance from the high-density magnetic field of an fMRI scanner has been developed. Extended haptic system was subjected to a series of tests to confirm electromagnetic compatibility with the fMRI scanner, for which key results are presented. With this fMRI compatible haptic platform a human brain activation during controlled upper limb movements can be studied. A simple virtual environment reaching task was programmed to study brain motor control functions. At the end preliminary results of an ongoing neurophysiological study are presented.
本文介绍了一款用于功能磁共振成像（fMRI）环境的Phantom Premium 1.5触觉设备的升级版。已开发出一种特殊的机械延伸装置，使触觉设备能够在距fMRI扫描仪的高密度磁场安全距离处运行。对扩展后的触觉系统进行了一系列测试，以确认其与fMRI扫描仪的电磁兼容性，并展示了关键测试结果。借助这个与fMRI兼容的触觉平台，可以研究受控上肢运动过程中的人脑激活情况。编制了一个简单的虚拟环境伸手任务程序，以研究大脑的运动控制功能。最后展示了一项正在进行的神经生理学研究的初步结果。
