CCVis: A Software Plugin for Unified Visualisation in ContraCancrum Based on VTK Extensions

Medical visualisation is an indispensable means for doctors and researchers to better explore and analyse medical images. The EC-funded ContraCancrum project, which aims at more predictable tumour simulation and treatment, uses visualisation as an important tool to interactively display tumour development and tumour simulation. This paper presents CCVis - the visualisation tool in ContraCancrum - which is a Qt-based plug in of the DrEye platform. CCVis uses a unified architecture for visualisation of the patient image data and tumour simulation data. It provides axis-aligned and arbitrary slice views, is surface rendering and volume ray casting as well as time-varying visualisation of patient image series and simulation data. Statistics in tumour simulation are plotted as 2D graphs. Major extensions of the Visualization Toolkit (VTK) are made to meet the demands for label highlighting and multi-dimensional transfer function.
