Gel2DE - a software tool for correlation analysis of 2D gel electrophoresis data.

Background: Two-dimensional gel electrophoresis (2DE) is a powerful technique for studying protein isoforms and their modifications. Existing commercial 2D image analysis tools rely on spot detection that limits analysis of complex protein profiles, e.g.

Real time image-based tracking of 4D ultrasound data.

We propose a methodology to perform real time image-based tracking on streaming 4D ultrasound data, using image registration to deduce the positioning of each ultrasound frame in a global coordinate system. Our method provides an alternative approach to traditional external tracking devices used for tracking probe movements. We compare the performance of our method against magnetic tracking on phantom and liver data, and show that our method is able to provide results in agreement with magnetic tracking.

A virtual reality solution for evaluation of radiotherapy plans.

This report presents a VR system for evaluation of treatment plans used in radiotherapy (RT), developed to improve the understanding of the spatial relationships between the patient anatomy and the calculated dose distribution. The VR system offers visualization through interactive volume rendering of RT dose distribution and computed tomography (CT) and surface and line rendering of RT structures such as target volumes and organs at risk. The VR system has been installed and networked in a hospital room used for the daily RT conferences, making stereoscopic viewing of treatment planning data for clinical cases possible.
