METHOD FOR THE PROVISION OF QUANTITATIVE CT IMAGE DATA ACQUIRED FROM A SCANNING FIELD VIA A DUAL-SOURCE CT DEVICE

摘要

A method is for provisioning quantitative CT image data acquired from a scanning field via a dual-source CT device the dual-source CT device including a first radiation source-detector system with a first capture region and a second radiation source-detector system with a second capture region. The method includes dividing the scanning field into a first subregion, representing at least a part of the intersection of the first region and the second capture region, and a second subregion, disjoint from the second region; acquiring first CT scan data from the first subregion and second CT scan data from the second subregion; reconstructing first quantitative CT image data from the first CT scan data and second quantitative CT image data from the second CT scan data; combining the first quantitative CT image data and the second quantitative CT image data to quantitative CT image data; and provisioning the quantitative CT image data.
