Visualisation pipeline used to create a 3D reconstruction and interactive application.
Table 1.
This table shows the datasets used for analysis of canine vascular neuroanatomy.
W: weighted; C: Contrast agent (gadolinium); VIBE: Volume Interpolated Breath-hold Examination; FLAIR: Fluid-attenuated inversion recovery; TE: Echo Time; TR: Repetition Time.
Table 2.
This table highlights the programmes used for the creation of the digital anatomy.
It demonstrates the programme used, where it is produced, the reason for its use in the study and the availability of it, as well as free alternatives that can be considered.
Table 3.
Name of vessel and nature of segmentation applied.
Fig 2.
This demonstrates the effects of smoothing in Amira.
Image 1 shows the surface generated with no smoothing, and image 2 shows the surface generated with unconstrained smoothing.
Fig 3.
This demonstrates the effects of smoothing in Amira.
Image 1 shows the surface generated with no smoothing. Image 2 shows the surface generated with constrained smoothing. Image 3 shows the surface generated with unconstrained smoothing.
Fig 4.
This highlights how the 3D model of the vasculature generated in Amira is “blocky”.
Fig 5.
This figure demonstrates the post-processing that was applied in 3DS Max.
The image on the left shows the original model generated in Amira being used as a template for the new model composed of cylinders. Image 2 shows the re-modelled appearance of the cerebral vasculature.
Fig 6.
This demonstrates the final development outcome of 3D model reconstruction of the vasculature and brain.
The arterial system is shown in red and the venous/sinus system in blue.

Structures segmented fro MRI and CT datasets.
Fig 7.
This demonstrates the interactive list feature.
The dorsal sagittal sinus was selected in this list, triggering a colour change of the vessel in the model.
Fig 8.
Screenshots demonstrating the options available for displaying the brain.
Image A shows the brain being displayed in ‘Opaque’ mode, image B shows the brain displayed in ‘Transparent’ mode and image C shows the model with the brain deactivated completely. The icons corresponding to each function are highlighted. The remaining icons appear darker to indicate they are inactive.
