A system and method for quantitative validation of the quality of image-guided interventional procedures. The system combines image data on the procedure with position tracking of the interventional instrument and calculates quantitative measures such as excursions of the interventional instrument from a desired position or track, procedure times and measurements of distances advanced and withdrawn. The quantitative metrics may be graphically displayed and stored. Metrics obtained for multiple users may be stored and statistically processed to derive measures of performance applicable to individuals or groups of clinicians.
