Method for Three-Dimensional Representation of a Moving Structure by a Tomographic Procedure

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method for creating three-dimensional images of moving structures using tomographic (imaging) techniques. By carefully selecting and processing projection images taken from various angles during multiple rotations, the method minimizes errors related to motion, thereby producing clearer and more accurate 3D representations, even when the subject is moving.

Patent Abstract

The invention relates to a method for three-dimensional presentation of a moved structure using a tomographic method, in which a plurality of projection images are recorded from different imaging angles between a start angle with a start node point and an end angle with an end node point by an imaging unit during a number of rotation passes, with three-dimensional image data being able to be reconstructed from the projection images, with the projection images being spaced by a path or an edge. For determining the three-dimensional presentation for each angle of projection only those projection images are selected which minimize the sum of the paths or weighted edges between adjacent projection angles for a gating.
