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