FIG 2. Detailed procedure of image reconstruction.
A, Reformatting protocol of the angiographic image into 460 secondary DICOM sections in 10-cm DFOV.
B, Examples of the sequential secondary DICOM sections including sections of the two aneurysms and most distal part of MPChA.
C, Raster gray scale 3D binary image output by (X) MedCon to AVS/Express. Note that the columns around the image are the patient’s data and image parameters. Under AVS/Express, image manipulation and cutting out of the region of interest is done as shown in panel D. The figure in panel D is the STL file output from AVS/Express to ICEM CFD. Panel E demonstrates the STL file in its mesh form in ICEM CFD. Finally, mesh reconstruction, smoothing, and closure of the inlet and outlet are done by using the mesh generator ICEM CFD before volume mesh generation and CFD calculation with Fluent on the tetrahedral mesh illustrated in panel F.
