Multi-orientation targeting set for MRI biopsy device

A biopsy device targeting set includes a vertical member, a carriage that is vertically movable along the vertical member, and a cradle coupled with the carriage. The cradle has a pair of substantially perpendicular mounting arms. Each mounting arm has a recess that may receive a rail of the carriage, such that the cradle may be mounted to the same rail in different orientations. Each mounting arm also has a biopsy device mounting feature, which may be a recess or a rail. The biopsy device mounting feature is configured to engage with a complementary feature of a biopsy device, such that a biopsy device may be mounted to either mounting arm. A z-stop feature is operable to selectively restrict longitudinal motion along either or both of the biopsy device mounting features. The targeting set may be used with a biopsy device in an MRI environment.
