Reduction of respiratory blurring in small-animal CT scans based on a fast retrospective gating method

[Abstract] The 22nd International Congress and Exhibition, Barcelona, Spain, June 25-28, 2008The purpose of the present work was to develop a fast retrospective method to extract the respiratory signal from the CT projections in cone beam geometry and to obtain dynamic breathing studies in small animal scans. The whole process had to be software-based and automatic, avoiding the use of any additional respiratory gating instrumentsPublicad
