Theses

A. Sippens Groenewegen (23-10-1990)

My collaboration with Arne Sippens Groenewegen started in 1987 when I did my masters thesis at the department of Medical Physics. For my MSc I wrote the programs fro the analysis of the 64 channel ECG's he and Hans Spekhorst were recording. 1.5 seconds long that just fitted in the 48kB RAM of the Apple II. Since then we have collaborated even when he was at the university of San Fransisco and when he was trying to start his own company. Things are a bit quite since he moved to Michican, but you never know..

A.C. Linnenbank (30-8-1996)

What can I say. This is my own thesis. As fiited for a graphics designer, this is the only one for which I do not have the digital source, so this is a scanned version. This cover is partly a pun on that of Arne. I tried to get the red/green/blue theme of the cover in every part of the defence and the party that night. I am still collecting pictures that are predominantly red/green/blue

P.F.H.M van Dessel (20-11-2001)

An important part of the research described in this thesis was performed on data recorded with a so called 'basket' catheter. This catheter can unfold 8 splines with 8 electrodes each. To show how this fits into a heart, the reconstructed basket is positioned in a transparent heart. The author of this thesis climbs mountains for a hobby, so a crystal heart was fitting. The ECGs that change into climbing ropes are another expression of the connectedness of work, research and other hobbies.

The chrystal heart was generated from a (coarse) MRI recording of a healthy subject. The basket orientation and shape are taken from one of the patients. The shape off the Matterhorn was generated from data supplied by the Bundesamt für Landestopographie in Switzerland.

M. Potse (3-12-2001)

The glass object is a Klein Bottle. This object has no inner and outer surface, just one connected surface (the handle pokes through the wall and connects to the top). In this thesis, recordings made on the body surface and recordings from the heart surfaces are investigated. The Klein bottle is an expression of the connectedness of both surfaces. The theses on the table are written by a number of predecessors in this field of research. From the bottom thesis to the one on top: A. Sippens Groenewegen, S.L.C. Muilwijk, A.C. Linnenbank, H.A.P. Peeters and P.F.H.M. van Dessel.

Although the defence of van Dessel was only two weeks before the defence of this thesis and the book was not printed yet, I could put it on the table because I made both. The table is modelled after a table that was used by H. van der Tweel (1915 - 1997). The work of van der Tweel and Durrer is the foundation for most of the work described in this thesis and in the ones on the table. In this thesis data recorded by endocardial balloons and basket catheters are investigated. Hence the balloon with basket on the cover. The colors of the balloon are from the 'Little Kahuna'. There is also a variation of this image that was used for the invitation to the graduation party.

T.M. Moojen (12-12-2003)

I met Thybout Moojen via Jeroen Snel. Thybout is a hand surgeon with whom Jeroen collaborated on solving the motion of the carpal bones. I refer to this image as 'the man with the golden hands', the carpal bones depicted are actually Thybout's. This image is close to one of my very first attempts. I did try to add more realism, but anything added just seemed to distract. I also did a different black and white with no background and no water for each chapter. At his defense I gave him a mug with another rendering, because 'I was tired of the gold and blue' one.

J. Langerveld (2004)

Jorina Langerveld is a cardiologist who did the PRAF study as her PhD project. The main difference with other renderings is in the colorscale. In the version for her thesis I went back to the old color scheme that was used by Durrer et al. for their seminal paper: total excitation of the isolated human heart Circulation 41:899-912, 1970. I also made the graphics for the invitation to the dinner and the party
