Abstract
A medical image processing apparatus comprises smoothing circuitry that receives a volumetric medical image data set corresponding to a 3D region of a subject and smooths the volumetric medical image data set to generate a smoothed medical image data set, wherein at least one part of the surface of a structure is represented in the volumetric medical image data set, rendering circuitry that produces a 2D rendered data set from the smoothed medical image data set, curvature calculation circuitry that calculates a respective curvature at each of a plurality of positions on the at least one part of the surface of the structure and smooths the calculated curvatures to obtain smoothed calculated curvatures, and shading addition circuitry that adds shading to the 2D rendered data set in dependence on the smoothed calculated curvatures.
