Our purpose was to improve the sharpness of the coronary stent and lumen. We reconstructed volume rendering (VR) image and maximum intensity projection (MIP) images using the original image and a sharpened operator image with 8-neighbor Laplacian filter. The most suitable center number was 9, and the circumferential number was −1 on the sharpened operator image with 8-neighbor Laplacian filter. In the same way, the most suitable spatial filter was the FC43. VR and MIP images showed sharp stents. The VR image and MIP image fused the original image and sharpened the operator image with the 8-neighbor Laplacian filter, resulting in a clear lumen. The 8-neighbor sharpened operator image with 8-neighbor Laplacian filter was attached to the Aquilion64, and this method did not require extra hardware and software for reconstructing images of the stent and lumen.
