Abstract

A method for generating at least one section of a virtual 3D model of a body interior, in particular a hollow organ, uses data that are provided by at least one endoscope introduced into the body interior. The data comprise at least one position and orientation of the endoscope, the at least one position and orientation being assigned at least one distance between the endoscope and the at least one point on a surface of the body interior, and at least one endoscopic image of the surface of the body interior in the region of the at least one point on the surface of the body interior. From the said data relating to a number of different positions and orientations of the endoscope is/are generated the section or sections of the 3D model in superposition with the associated endoscopic image. An appropriate apparatus is also described.
