Clinical Specialty Details

Dr. Ptak established the first whole-body, multi-planar screening trauma evaluation using volumetric CT technique, first introduced in 1998-99. He was the first to publish and present on this technique nationally in 1999, thus influencing and establishing imaging beyond standard single body segment axial imaging for the evaluation of multi-trauma patients.
