Volumetric Visualisation
Volumetric visualisation techniques can be used to create 3D representations of 2D patient data, such as MRI, CT, and PET scan images. 3D Slicer, open-source image computing platform, was used to produce 3D visualisations of complete data sets (Direct Volume Rendering), as well as segmented models of individual anatomical structures of interest (Indirect Volume Rendering).
Brain tumour | spatial relationship with the surrounding structures
Indirect volume rendering was used to construct models of the tumour (PET scan data), the brain (MRI scan data) and the skull (CT scan data). Once combined, the opacities of the brain and skull were adjusted to show the spatial relationship of the tumour to the surrounding organs.
brian tumour | The structure and the surrounding organs
The structure of the tumour was visualised from the MRI scan data using Direct Volume Rendering, allowing the density of the tumour to be visualised and compared to that of the surrounding organs. Cropped views from the (a) right side and (b) anterior to enable viewing of the tumour.
