Two commercially available plastic keyboards were contrasted in the degree to which they interfered with echo planar imaging. One keyboard (GrandTec USA's "Virtually Indestructible Keyboard") caused significantly less temporally variant and invariant signal loss and was integrated into a MRI interface system for recording participants' manual motor responses. The response recording system is safe, accurately records reaction time behavioral data, and does not interfere with functional data collection. Implementing this MRI-compatible keyboard allows the collection of motor responses from complex manual behaviors (i.e., typing) and thus represents a valuable tool for functional MRI (fMRI) studies.
对两款市售塑料键盘在干扰回波平面成像的程度方面进行了对比。一款键盘（美国格兰泰克公司的“几乎坚不可摧的键盘”）造成的随时间变化和不变的信号损失明显更少，并被集成到一个用于记录参与者手动运动反应的MRI接口系统中。该反应记录系统安全，能准确记录反应时间行为数据，且不干扰功能数据收集。使用这种与MRI兼容的键盘能够收集复杂手动行为（即打字）的运动反应，因此是功能磁共振成像（fMRI）研究的一种有价值的工具。
