  Figure 1. A 3-dimensional (3D) reconstruction image as part of preoperative imaging provided by the radiology department. Sample images from preoperative computerized tomography study providing routine 3 standard planes and the 3D image reconstructed from these images. In everyday practice, the diagnosis and surgical planning are based on these images. A, Axial view. B, Sagittal view. C, Coronal view. D, 3D reconstruction.

  Figure 2. The process of virtual intravascular endoscopy to visualize the aorta from inside and outside and to manipulate it with desired cut and section planes. A, Aorta with deletion of all other structures. B, Free selection of an arbitrary cut plane with surgical importance to view the position of the dissection flap; the red line indicates the free-hand selection by the user. C, Once the area is selected and complete, the program automatically highlights it. D, By clicking DELETE, the marked area is removed. E, The geometry is freely rotated to view the inside from any angle of choice. F, The end result of a similar process to view from the left side of the aorta, illustrating the dissection flap (arrow) and its position, the true lumen (TL) and the false lumen (FL) (steps are not shown).
