Coronary Artery Stenosis Phantoms

For the analysis of various case studies on coronary heart disease

Analyse different case studies for coronary artery disease
3 different sets with various plaque and lumen combinations available
Ideal to use in combination with QRM Thorax Phantom (QRM-20100)

Three different sets simulating diverse plaque materials and different stenosis are available. The sets cover diverse scenarios combining three plaque materials (Fibro-fat, Lipid and Ca-enriched) with eccentric and concentric stenosis. To mimic non-contrast and contrast scans, each set includes phantoms with blood-equivalent and iodine-enhanced lumen.

QRM-60106 (Set of 6 coronary artery phantoms): 17%, 33%, and 50% eccentric stenosis in each phantom, 6 different material combinations of different plaques/vessel lumen. All phantoms with vessel wall.

QRM-60107 (Set of 4 coronary artery phantoms): 50% eccentric stenosis; 3 different plaque materials in each phantom, 2 different lumen materials with & without a vessel wall.

QRM-60108 (Set of 6 coronary artery phantoms): 67% and 33% concentric stenosis in each phantom, 6 different material combinations of different plaques/vessel lumen. All phantoms with vessel wall.

With the specially designed holder (QRM-60109), up to three coronary artery phantoms can be placed within the QRM water tank phantom (QRM-10113). The water tank can be combined with the optional available thorax phantom (QRM-20100) to provide mimic a (semi-)anthropomorphic measurement environment.

Customized: Other plaque and lumen geometries with various concentrations of Iodine, CaHA and other cardiac relevant materials are available upon request.
