Project Details

Project:
Navigated gamma probes for tomographic reconstruction

Supervisors:
Prof. Nassir Navab
Prof. Sibylle Ziegler

Start of PhD-work at GSISH:
January 2012

Project Description:
Functional imaging systems for intraoperative guidance have shown remarkable results. These results, even tough very positive in some cases, tend to suffer from high variability, highly correlated with the experience of the operator. A highly trained user produces datasets that, once reconstructed, can rival a gantry-based SPECT machine, while a novice user usually cannot get similar results.
At the same time, new hand-held detectors have been developed, and it is now possible to use a 2D gamma camera with hundreds of pixels instead of a single detector device. This new detector opens the door for faster acquisitions and better quality reconstructions, but presents big challenges for the calibration,  acquisition pipeline and the reconstruction schemes. The proper solution to those challenges is critical to exploit the advantages of this new detectors.
This work presents the first steps towards solving those problems.
