Classification: CPC A  G  Y | IPC A  G

Claim 0:
1. A normalization device configured to normalize a medical image of a coronary region of a subject for an algorithm-based medical imaging analysis, the normalization device comprising:
a substrate configured in size and shape to be placed in a medical imager along with a patient so that the normalization device and the patient can be imaged together such that at least a region of interest of the patient and the normalization device appear in a medical image taken by the medical imager;
a plurality of compartments positioned on or within the substrate, wherein an arrangement of the plurality of compartments is fixed on or within the substrate;
a plurality of samples, each of the plurality of samples positioned within one of the plurality of compartments, and wherein a volume, an absolute density, and a relative density of each of the plurality of samples is known, the plurality of samples comprising:
a set of contrast samples, each of the contrast samples comprising a different absolute density than absolute densities of the others of the contrast samples;
a set of calcium samples, each of the calcium samples comprising a different absolute density than absolute densities of the others of the calcium samples; and
a set of fat samples, each of the fat samples comprising a different absolute density than absolute densities of the others of the fat samples; and
wherein the set contrast samples are arranged within the plurality of compartments such that the set of calcium samples and the set of fat samples surround the set of contrast samples.
