Abstract
A method is described for evaluating substance scoring, the scoring based on imaging system-generated images of an object having regions of interest due to possible presence of the substance, the method including the steps of simulating the regions of interest using a phantom having a plurality of volumes, each volume having dimensions simulating dimensions of a region of interest, each volume having a density representative of a substance density; generating images of the phantom; scoring the substance based on the phantom images; and comparing results of the substance scoring to expected phantom-image results. The above-described phantom and method allow a scoring system user to verify substance scoring accuracy and to compare scores resulting from different imaging systems, scanning methods and reconstruction algorithms.
