Abstract
A fluoroscopy image is registered with data representing a volume, identifying a catheter position relative to a volume represented by preoperative volume data. The catheter position relative to a patient volume represented by data acquired without scanning the catheter is displayed. For example, a 2D fluoroscopy image is registered with respect to coordinates of a 3D preoperative CT or MRI volume by registering the fluoroscopy image and the preoperative volume to 3D ultrasound coordinates.
