Experience

In this position I designed and implemented a software framework called DTITool3 for medical visualization with the following features:

• Management of large medical data sets in various input formats,
• Plug-in framework that allows straightforward implementation of new functionality,
• Run-time loading and unloading of plug-ins to speed op the plug-in development cycle,
• Good documentation and APIs so that new developers and students get started easily.

In December 2009 I concluded my PhD project in the Biomedical Image Analysis group of prof. Bart ter Haar Romeny under supervision of Anna Vilanova, by successfully defending my PhD thesis titled GPU-based Visualization Techniques for the Interactive Exploration of Diffusion MRI Data. The topics of my PhD project included:

• Analysis of distance/similarity measures for diffusion tensor imaging (DTI),
• Intuitive new methods for visualizing the fibrous structure of healthy and ischemic hearts,
• GPU-accelerated glyph rendering methods that visualize local diffusion information, represented by tensors or spherical harmonics, in different types of diffusion MRI data,
• The architectural design and implementation of our own visualization tool called DTITool.

In the final year of my master studies, I worked on the visualization of DNA sequences and their annotations (which can specify, for example, where certain genes are encoded in the sequence) in the visualization group of prof. Jack van Wijk. Because these are very large data sets, a good visualization tool was needed to investigate them. After studying molecular biology and investigating existing tools, I created a new tool called DNAVis. This tool makes it possible to interactively view and compare annotated DNA sequences. DNAVis makes use of existing visualization techniques such as linked windows, perspective walls and semantic zooming. My Master's thesis was titled Interactive Visualization of Annotated DNA Sequences.

The biologists of Plant Research International (PRI) received DNAVis with great enthusiasm. They will use the tool and further develop it together with the visualization group of prof. Jack van Wijk of the department of Mathematics and Computer Science of the TUE.

I worked for three months in the department of Biomedical Engineering on a C++ library that makes several visualization methods of VTK (The Visualization Toolkit) available for EasyScil, the development environment for EasyVision (now ViewForum of Philips Healthcare).

The goal of this project was to gain experience in project management in larger software projects. In 6 months we developed with a group of 9 students a system named DigLib for Océ. DigLib is a document management system that can store, view, index/search and categorize groups of documents in different formats (e.g. PDF, TIFF). Users with different roles can connect to the system via an intranet and/or internet environment. I was responsible for the implementation of a web-based user interface using JSP and Java servlets, quality management, and I shared responsibility for the design of the system.
