2D and 3D virtual intravascular endoscopy (VIE) synchrotron radiation computed tomography images of model 1. (A and B) 2D axial images with beam energy of 30 keV and reconstructed with different slice thicknesses. Long arrows point to the plaque at left main stem (LM), while short arrows refer to the plaque at left anterior descending arteries (LAD). (C) VIE images of plaque at LM acquired with beam energies of 30, 40 and 50 keV and reconstructed with different slice thicknesses. Images with use of 30 keV beam energy demonstrate best visualization of the coronary wall and plaque appearance when compared to those with 40 and 50 keV beam energies. Visualization of coronary wall and plaque is significantly affected in images with 0.491 mm slice thickness. (D) VIE views of plaque at LAD with beam energy of 30 keV and different slice thicknesses. Plaque shape or configuration was changed in images with a slice thickness of 0.491 mm.
