Abstract:
1. An imaging system comprising: an imaging transducer operable to receive signals for creating an image of an object during performance of a procedure; an instrument guide coupled to the imaging transducer, the instrument guide operable to provide guidance for movement of an instrument during performance of the procedure; and an opto-mechanical sensor system disposed on the instrument guide, the opto-mechanical sensor system including: wherein the rotatable interface surface is arranged to be biased by the spring against an instrument that is positioned between the instrument guide and the rotatable interface surface such that movement of the instrument with respect to the instrument guide rotates the encoded sensor surface between the light source and the optical detector and an arc of rotation of an outer axel of the encoded sensor surface is larger than an arc of rotation of the axel of the interface surface, thereby multiplying the magnitude of the motion of the instrument, and wherein the opto-mechanical sensor system is operable to provide instrument movement information regarding movement of the instrument during performance of the procedure.
