Electromagnetic Tracking of Devices During Biopsy Procedures
The purpose of the trial is to evaluate the differences between PercuNav assisted and unassisted biopsy in the areas of CT radiation dose, procedure time and biopsy accuracy.
This prospective, randomized, controlled trial will compare the use of electromagnetic tracking and image guidance (CT) during biopsy procedures verses the typical CT image guided procedure alone.

- Radiation Dose [ Time Frame: 24 hrs ] [ Designated as safety issue: No ]The primary objective of this study is to assess and quantify any differences between assisted and unassisted CT guided biopsy procedures of the liver with respect to radiation dose.
- Total procedure time [ Time Frame: 24 hrs ] [ Designated as safety issue: No ]Total procedure time is determined by the timespan of the moment the patient is accepted into the room (start) and the time when the procedure is complete (finish - when physician exits room).
- Accuracy of needle targeting [ Time Frame: 24 hrs ] [ Designated as safety issue: No ]Distance from defined target on PercuNav and angle of entry
