ABSTRACT
The availability of post-processing techniques is inversely proportional to their computational complexity. Adding up all the voxels of the volume and applying a post-processing algorithm such as volume rendering will result in the anatomical representation of the data set. Isotropic imaging is preferred because post-processing from isotropic voxels creates sharp images while anisotropic voxels may create less distinct images. Volume rendering requires preprocessing tissue types contained in each voxel. The usefulness and quality of image post-processing is highly related to the in-plane and through-plane resolution of multislice CT. The data that form the computed tomography (CT) slice are sectioned into elements, the width indicated on the x-axis and the height on the y-axis. Spiral CT creates two-dimensional images oriented in an axial plane. The parameters for image reconstruction in CT coronary angiography typically are slice thickness of 1 mm reconstruction increment 0.5 mm, and field of view 150 mm.
