The control module interface is configured to provide an interface between the control module and the reusable portion of the biopsy device. The at least one wireless data communication link includes a first data link configured to permit communication of data between the reusable portion of the biopsy device and the control module interface. The encoder is operationally coupled with the MR compatible motor.
