Abstract
An interventional tool stepper (30) employing a frame (31), a carriage (33), an optional gear assembly (32), and an optional grid template(34). The frame (31) is structurally configured to be positioned relative to an anatomical region for holding an interventional tool (40) relative to the anatomical region. The carriage (33) is structurally configured to hold the interventional tool (40) relative to the anatomical region. The gear assembly (32) is structurally configured to translate and/or rotate the carriage (33) relative to the frame (31). The grid template (34) is structurally configured to guide one or more additional interventional tools (41) relative to the anatomical region. The frame (31), the carriage (33), the optional gear assembly (32) and the optional grid template (34) have an electromagnetic-compatible material composition for minimizing any distortion by the interventional tool stepper (30) of an electromagnetic field.
