Abstract
A method of analyzing a volumetric data set obtained by an imaging system from an object is provided includes defining a first region of interest comprising a population of voxels of a first tissue part of the object to obtain a first distribution of radiation attenuation coefficient values, defining a second region of interest comprising a sample of voxels of a second tissue part of the object to obtain a second distribution of radiation attenuation coefficient values, and distinguishing the second tissue from the first tissue using the properties of the first and second distributions of radiation attenuation coefficients.
