Abstract
A magnetic resonance imaging (MRI) compatible core biopsy system uses a biopsy device having intuitive graphical displays and a detachable remote keypad that advantageously allows convenient control even within the close confines afforded by a localization fixture installed within a breast coil that localizes a patient'"'"'s breast and guides a probe of the biopsy device relative to the localized breast. A control module for interactive control and power generation are remotely positioned and communicate and transmit rotational mechanical energy via sheathed cable.
