Project Details

Quantitative X-ray phase-contrast tomography for biomedical research at laboratory X-ray sources

Prof. Dr. Franz Pfeiffer

Start of PhD-work at GSISH:
June 2011

Project Description:
Grating-based X-ray phase-contrast tomography is an emerging modality that is based on a fundamentally different image formation process compared to conventional attenuation-based imaging and might improve diagnostics in the future by providing additional information and enhanced soft-tissue contrast.
In this project, we investigate the potential of the technique for quantitative tissue characterisation and aim to gain insight into its diagnostic capabilities. For this purpose, an experimental phase-contrast imaging system optimised for biomedical research has been developed in our lab. Various studies are performed in strong collaborations with the Radiology Departments of the Klinikum rechts der Isar and the Klinikum Grosshadern. Topics range from oncology to fibrosis and atherosclerotic plaque.
