1. A method for quantitatively registering a 2D endoscopic region of interest (ROI) in a 3D volumetric imaging dataset, the method comprising:
- receiving signals representing the volumetric imaging dataset;
receiving signals representing an endoscopic dataset from an endoscope, the endoscopic dataset including an endoscopic imaging dataset and a tracking dataset, the tracking dataset including information about the position and orientation of the endoscope;
wherein coordinates of the endoscopic dataset and coordinates of the volumetric imaging dataset are registered to a common coordinate system;
receiving a definition of the 2D endoscopic ROI within the endoscopic imaging dataset;
generating a 3D surface ROI within the volumetric imaging dataset corresponding to the 2D endoscopic ROI, based on a projection of the 2D endoscopic ROI to the registered common coordinate system; and
transmitting signals representing the generated 3D surface ROI for treatment planning.

Abstract
A method, computer program product and processor for quantitatively registering a 2D endoscopic ROI in a 3D volumetric imaging dataset. An endoscopic dataset and a volumetric imaging are registered to a common coordinate system. A 2D endoscopic ROI is generated within the endoscopic imaging dataset. A 3D surface ROI is generated within the volumetric imaging dataset corresponding to the 2D endoscopic ROI, based on a projection of the 2D endoscopic ROI to the registered common coordinate system.
