Virtual endoscopy with improved image segmentation and lesion detection
First Claim
1. A computer-implemented method for interactively displaying a three-dimensional rendering of a structure having a lumen comprising the steps of:
- a. forming a three-dimensional volume of data from a series of two-dimensional images representing at least one physical property associated with the three-dimensional structure;
b. generating a wireframe model of a selected region of interest;
c. deforming the wire frame model using a geometric deformable model to more accurately represent the region of interest; and
d. rendering the wireframe model in an interactive three-dimensional display.

Abstract
A system, and computer implemented method are provided for interactively displaying three-dimensional structures. Three-dimensional volume data (34) is formed from a series of two-dimensional images (33) representing at least one physical property associated with the three-dimensional structure, such as a body organ having a lumen. A wire frame model of a selected region of interest is generated (38b). The wireframe model is then deformed or reshaped to more accurately represent the region of interest (40b). Vertices of the wire frame model may be grouped into regions having a characteristic indicating abnormal structure, such as a lesion. Finally, the deformed wire frame model may be rendered in an interactive three-dimensional display.
