Minimally invasive percutaneous procedures are increasingly indicated and used in modern medicine. For example, percutaneous biopsies and thermal ablations are common in the growing field of image-guided interventional oncology.1,2 These procedures have been increasingly used to diagnose and treat hepatic, renal, and other soft tissue tumors, especially in patients not eligible for surgical resection.3–6 One drawback is that images used for guidance in these minimally invasive methods are displayed on fixed two-dimensional (2D) monitors, and some, including computed tomography (CT), expose the patient to radiation.7 Furthermore, targets for percutaneous procedures are often in sensitive or difficult-to-access locations and current image guidance is often not ideal due to issues with two-dimensionality.
