MSc thesis

Currently doing my masters thesis in the field of medical visualization at Delft, University of Technology. For my masters thesis I will apply state-of-the-art real-time volume visualisation techniques to a high resolution collection of histological sections and a matching MRI dataset. In addition, I will integrate flexible interaction to facilitate exploration of the data. The main topic of research is to investigate the utility of focus+context and illustrative visualisation techniques. A secondary goal is to explore the use of such volume visualisation as an aid in the planning of total mesorectal excision surgery.

The distinctive feature of the system is Example-based Appearance Specification (EbAS). The users will be able to specify the appearance of physical objects in the dataset using live previews of the actual data, as opposed to the natural language of the domain of the technique, which they are unfamiliar with. If possible, the system will use semantic layers [Rautek 07] for specification of mappings not involving physical objects, and style transfer functions ( [Bruckner 07a]) for general transfer function specification.

The user interacts with the visualization by use of (GUI) widgets and gpu-based clipping techniques. In order to maximize ease of interaction, the use of two-handed interaction techniques will be researched. Two-handed interaction techniques match with our strong bimanual motor skills and might make interaction with the visualization more straightforward. Furthermore, interaction-dependent semantic layers ( [Rautek 08b]) will enable the user to customize interaction with the data according to their requirements.
