Abstract

A Method for performing a CT imaging process depending on an individual respiration behaviour of a patient (P) is described. The method comprises the step of recording a respiratory movement of a patient (P) by monitoring an intrinsic respiratory surrogate (IRS). In the context of the recordation of the intrinsic respiratory surrogate (IRS), CT raw data (RD) are acquired from an examination volume (V) of the patient (P). Then, 3D-CT images of subsequent stacks (ST_i) of the examination volume (V) at different z-positions are reconstructed. An automatic organ segmentation is performed based on the reconstructed 3D-CT images of the subsequent stacks (ST_i), wherein at least one portion of the examination volume (V) is segmented. Furthermore, a respiratory movement of the segmented portion is detected and determined as the intrinsic respiratory surrogate (IRS). The method further comprises the step of adapting the CT imaging process based on the intrinsic respiratory surrogate (IRS) of the patient (P). Further, an adaption device (70) is described. Furthermore, a CT system (1) is described.
