Picking on fused 3D volume rendered images and updating corresponding views according to a picking action

摘要

A method of point picking on a fused volume rendered view of multiple registered volumes having the following steps:- selecting a rendered pixel,- finding the projection ray through the rendered pixel,- finding the intersection segment of the projection ray with the fused volume,- traversing the intersection segment according to a traversing intersection point,- calculating the intermediate fused volume rendered value at each traversing intersection point,- evaluating a stop condition at each traversing intersection point leading to a final fused volume rendered value,- outputting the coordinates of the traversing intersection point where the stop condition was reached as the picked point.
