Dirk Bartz in Memoriam

cpbotha — Tue, 30 Mar 2010 11:52:29 +0000

Yesterday we received the very sad news that our friend and colleague Dr. Dirk Bartz unexpectedly passed away on Sunday. We wish his family much strength in these difficult times.

He will be sorely missed.

Submit your VCBM 2010 papers!

cpbotha — Fri, 26 Feb 2010 18:04:27 +0000

There is still time to submit those great biomedical visual computing application papers that you have lying around! The VCBM 2010 deadline is not quite upon us yet, so hurry on up.

I hope to see you all in Leipzig at the beginning of July!

Dynamic Medical Image Visualisation at ISPA 2009

cpbotha — Thu, 26 Feb 2009 16:00:09 +0000

The Bergen MedViz Network is organising a special session on the Analysis and Visualization of Dynamic Images in Medical Applications at the 6th International Symposium on Image and Signal Processing and Analysis (ISPA) 2009.

Topics of interest include but are not limited to:

Study of perfusion using MRI, CT, US, or PET
Motion correction of image time series
Strain and stress imaging
Imaging of the beating heart, or the moving kidney
Tracking of cells, organelles, or proteins in time-lapse images
Compartment modeling and tracer kinetics in MRI, CT, or PET
Flow quantification and visualization
Analysis and visualization of change (e.g. displacement) in repeated image examinations
Image-based modeling and visualization of dynamic biological processes (e.g. diffusion)

We have good friends and colleagues in the Bergen MedViz network, so this is bound to be good. Submit your papers!

ECR 2008

cpbotha — Sun, 09 Mar 2008 00:27:32 +0000

I’m currently at the European Congress of Radiology (ECR) 2008, staffing the Medical Delta booth in the Imagine section (level 2 in the Austria Centre, close to rooms X and Y), together with a number of cool people from the Erasmus Medical Centre Biomedical Imaging Group Rotterdam and the Leiden University Medical Centre Image Processing Laboratory. If you’re reading this and you’re in the neighbourhood, pop by for a chat and of course some complimentary stroopwafels and drop!

Update:

I’m back at the TU in Delft and the ECR should be finising by this afternoon. Also see the blog summaries of Marion Smits by clicking here, here and here. Below is a photo Marion took of our Medical Delta booth:

Siemens unveils MR-PET prototype

cpbotha — Sun, 27 May 2007 12:05:46 +0000

Siemens has unveiled the world’s first MR-PET scanner prototype. With this imaging system, magnetic resonance imaging (MRI) and positron emission tomography (PET) images can be acquired simultaneously. MRI supplies anatomical (structural) information as context, whilst PET yields functional data, for example on the precise location of tumours and their metastases. See the image below for an example (courtesy of Siemens):

This is yet another new example of “native” multi-field medical datasets, and underlines the need for research on techniques that are able to visualise this type of data.

Virtual colonscopy best method for screening

cpbotha — Wed, 25 Apr 2007 13:41:23 +0000

Virtual Colonoscopy with an optical colonoscopy followup, where non-diminutive lesions (< 6mm) are not reported, has been found to be the most cost-effective and safest method for screening. See this MedGadget blog, and this abstract in Cancer for more details.

The TU Delft Visualisation Group is also actively performing research on Virtual Colonoscopy. Our current focus is on automatic polyp detection by using vector field visualisation techniques. Click here for the research project page, or read “L. Zhao, C. P. Botha, J. O. Bescos, R. Truyen, F. M. Vos, and F. H. Post, Lines of curvature for improved diagnosis in virtual colonoscopy, IEEE Transactions on Visualization and Computer Graphics, 2006″ (you can find this article on the group publications page).

Update:
Gerwin has just notified us of a new WebMD article also on this virtual colonoscopy study, this time concerning a new article published in the October 4 2007 issue of the NEMJ.
