Method of processing a volumetric dataset and a method of rendering a volumetric dataset

摘要

A method of processing a volumetric dataset for imaging includes receiving a volumetric dataset comprising data for imaging and determining an irradiance value at a given point in the volumetric dataset. In an embodiment, the method includes performing a selection process to select one or more of a plurality of irradiance data structures and storing the irradiance value in the or each selected irradiance data structure.
