摘要：
A magnetic resonance imaging (MRI) compatible sensor for measuring torque with respect to an axis of rotation in conjunction with an applied linear force includes a shaft arranged in a longitudinal direction substantially along the axis of rotation, a base component arranged along the axis of rotation and displaced with respect to the shaft, a torque detector assembly configured to be coupled to rotational motion of the shaft about the axis of rotation relative to the base component, and a linear-force detector assembly configured to be coupled to linear motion of the shaft from a force applied in a direction substantially coincident with the axis of rotation relative to the base component. The torque detector assembly and the linear-force detector assembly are substantially de-coupled from each other such that torque measurements are substantially independent of linear force measurements. The MRI compatible sensor consists essentially of MRI compatible materials.
