Problems solved by technology

[0010] 4D volume renderers and dynamic MPR are currently available: see for example "4D volume Rendering With The Shear WarpFaorisation" by Kostas Anagnostou, Tim J. Atherton, Andrew E. Waterfall (Proceedings of the 2000 IEEE Symposium on Volume Visualization., p. 129 -137 pages, 2000); however, this material does not describe the 4D virtual endoscopy system

Embodiment Construction

[0033] For purposes of greater clarity, the invention will be described in terms of exemplary embodiments; however, it will be understood that detailed descriptions of specific embodiments are not intended to limit the invention, but rather to aid in illustration. It will be appreciated that references in this context to eg cameras and camera accessories generally refer to virtual equivalents.

[0034] According to aspects of the present invention, a general framework of a method and system for an interactive 4D virtual endoscopy system includes:

[0035] Reconstruction of 4D volumes from 3D images;

[0036] Draw a dynamic endoscopy scene;

[0037] Interactively manipulate the virtual endoscope; and

[0038] Interactively adjust system parameters.

[0039] 4D CT and MR volumes are obtained directly from the scanner. Descriptions of these methods are available in the literature and need not be repeated in detail here. Therefore, in this description of an embodiment of the ...

Abstract

A method for performing four-dimensional virtual endoscopy, includes capturing a heart image sequence of a patient by an imaging equipment and a electrocardiagram signal displaying a cardiac cycle of the heart. The electrocardiagram signal is used to select images to derive the corresponding three-dimensional view successively in the corresponding cardiac cycle with the corresponding heart image in the common and selected phase point of each corresponding cardiac cycle.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS AND CLAIM OF PRIORITY [0002] With specific reference herein to co-pending U.S. Provisional Patent Application No. 60 / 857,637 (Attorney Docket No. 2006P23957 US) filed on November 8, 2006 by inventors HERVE LOMBAERT, FRANK SAUER, YIYONGSUN, CHENYANG XU, And this U.S. Provisional Patent Application is titled Interactive 4D Virtual Endoscopy for Cardiac Imaging, and the disclosure of which is incorporated herein by reference, and claims this U.S. Provisional Patent The right of priority of the application. technical field [0003] The present invention relates generally to interactive four-dimensional (4D) imaging, and more particularly to four-dimensional virtual endoscopy for cardiac imaging. Background technique [0004] Virtual endoscopy allows visualization of a scene built from pre-captured data. Images are generated using a virtual camera interactively manipulated by a user. Below, first a brief review of the imaging te...
