Three dimensional image volume reconstructing method for patient, involves recording two individual projection images in constant relative position between focus point and region of interest

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

This invention presents a method for reconstructing three-dimensional (3D) image volumes, such as medical scans, from two individual two-dimensional (2D) projection images. The process maintains a constant relative position between a fixed focus point and the region of interest during image capture, enabling the creation of an extended projection image and accurate computation of the 3D volume via back-projection of grey values.

Patent Abstract

The method involves computing grey values of voxel of image volume by rear projection of the projection image. The two individual projection images are recorded in constant relative position between a focus point and a region of interest (5). Rotation angles of the two individual projection images are arranged in a plane. The two individual projection images are constructed, and are put together to an extended projection image. An independent claim is also included for an X-ray machine for implementing the method for reconstructing three dimensional image volume from multiple two dimensional projection images of a region of interest.
