Abstract
The invention relates to a tomography system (TA) comprising a first (QD) and a second (QD) beam source-detector pair for capturing one series (A, A) of projection image data sets (PB, PB) each from one projection angle (W, W) each and a volume image production system (VE) for producing a series (AV) of volume images (VB) of a vascular system (GS) while taking into account first confidence values (VW) of the first pixel values (PW) and/or while taking into account second confidence values (VW) of the second pixel values (PW). The confidence value (VW, VW) of a pixel value (PW, PW) depends on a pixel-specific traversing length (L) that a projection beam (PS, PS) traverses on a path through parts (Gi) of the vascular system (GS) from the first (Q) or the second (Q) beam source to a pixel-specific sensor element (S) of the associated first (D) or second (D) detector. The invention further relates to a corresponding method () for producing a series (AV) of volume images (VB) of a vascular system (GS).
