Patient specific coronary arteries with stenosis: significant stenoses are indicated by arrows, and the severities of the stenoses were determined by the structural assessment based on the cross-sectional area of the lumen. The distribution of the isolated stenosis varies between cases, and serial stenosis were found in case 2 and case 3. S stenosis; PS proximal stenosis; DS distal stenosis. For case 1, the stenosis was in the middle of the left anterior descending coronary artery of length 3.28 mm; for case 4, the stenosis was in the middle of the right coronary artery of length 8.34 mm. In case 2, the stenosis was of lengths 3.98 and 2.32 mm distributed at the bifurcation of the LAD and distal daughter branch; in case 3 the stenosis was of lengths 4.84 and 2.11 mm, distributed at the adjacent bifurcation in the LAD. The reconstruction based calculated stenosis percentage areas of the four cases were 56.25% in case 1, 49.54 and 54.97% for the proximal and distal stenosis in case 2, 67.2 and 35.23% for the proximal and distal stenosis in case 3, and 62.3% in the middle of RCA in case 4
