Diplomarbeit / Masterarbeit / Bachelor thesis (DA/MA/BA): Confidence visualization and robust inference based on tracking for beta probe surface reconstruction

Advisor: Nassir Navab
Supervision by: Thomas Wendler

Abstract

The main problem of current beta probe surface reconstruction is the sparse nature of the data used for it. A proper reconstruction scheme and visualization could assist the surgeon in the acquisition of measurement points that guarantee a valid reconstruction and thus minimize the risk of false interpretation and wrong therapy planning. This diploma thesis will evaluate strategies to solve this problem by means of grid discretization (rebinning), robust inference, and determination of a value of confidence for every defined grid point. Furthermore, a strategy the diploma thesis will investigate a proper visualization method to display the confidence level at grid points and the robustly reconstructed surface.
