Figure 2
Axial CT images of the coronary vessel phantom of nine stenosis models with calcified plaques. Clockwise, in turn, is 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90% stenosis. (A) nine different stenoses of calcified plaques without de-blooming algorithm using standard mode reconstruction. (B) nine different stenoses of calcified plaques using standard mode reconstruction with de-blooming algorithm. The degree of stenosis of calcified plaques was less severe due to suppression of blooming artifacts as observed in B when compared to A. (C) nine different stenoses of calcified plaques using high definition standard mode reconstruction without de-blooming algorithm. The degree of stenosis of calcified plaques was less severe compared to images on A, but was more serious when compared to images on B. (D) nine different stenoses of calcified plaques using high definition standard mode reconstruction with de-blooming algorithm, compared with B and C, the degree of stenosis of calcified plaques was less obvious.
