Dynamic determination of equivalent CT source models for personalized dosimetry

Stephan Rosendahl / Ludwig Büermann
Published Online: 2017-09-07 | DOI: https://doi.org/10.1515/cdbme-2017-0167


With improvements in CT technology, the need for reliable patient-specific dosimetry increased in the recent years. The accuracy of Monte-Carlo simulations for absolute dose estimation is related to scanner specific information on the X-ray spectra of the scanner as well as the form filter geometries and compositions. In this work a mobile measurement setup is developed, which allows both to determine the X-ray spectra and equivalent form filter of a specific scanner from just one helical scan in less than 2 minutes.

Keywords: CT; Personalized Dosimetry; X-ray Spectra; Bow-Tie Filter
