ABSTRACT:
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.
