To generate an optimized 3D visualization of an angiographic exam, it is possible to easily remove table and bones and thus obtain an occlusion-free view of the vasculature. You can use the Remove Table tool, for example, to visualize the body region of interest without interfering structures. You can use the Remove Bones tool to remove the bone voxels from the baseline of the scan and to achieve a vascular-only view. Both tools can be found in the Tool Gallery.   Text explanation is visualized in this video snippet without audio. The orientation cube helps you to interactively change the view in the segment. Click one side of the orientation cube to display the corresponding orientation.   Click the orientation cube to rotate the cube by 90°.   Double-click the orientation cube to restore the initial orientation in the selected segment.   Right-click the orientation cube and choose an orientation from the context menu.   Right-click the orientation cube and choose Reset position in all segments from the context menu to reset all segments to the orientation in which the images originally displayed after loading.   Text explanation is visualized in this video snippet without audio. Ranges allow you to reformat volumetric data as a series of images, for example, to create other anatomical planes or projections, or for better visualization. You can create parallel, radial, radial sliced, curved, spine and vascular ranges for different body regions.  To do this, select a Range tool from the top left corner menu or from the Tool Gallery. You can either define your own range limits, or use the range presets for the automated reconstruction process. These range presets contain the position and orientation of a range as well as the number of images and the image thickness.   Text explanation is visualized in this video snippet without audio.
