Quantitative DECT with prior atlas knowledge Dual-Energy CT (DECT) uses two different x-ray spectra
simultaneously. This technique enables decomposition of images into the underlying materials by detecting the different attenuation of materials at different x-ray spectra. Thus, the diagnostic significance of DECT is improved compared to single-energy CT. So far, the method of material decomposition is only efficient for certain
organs and works only with organ-specific parameters. The
organ-specific parameters have to be given by the user manually, and the parameters should be chosen patient-specifically.
This project aims at decomposing the materials with anatomy
knowledge automatically. An atlas provides the prior knowledge - the anatomic structures. The anatomy knowledge allows then automatic decomposition and classification of the different materials.
This project is in cooperation with the German Cancer Research Center (DKFZ) Heidelberg and the University Hospital Erlangen. | Project manager: Prof. Dr.-Ing. habil. Andreas Maier
