VICBCT- and 4D-CT-based ventilation images (VICT) were derived by DIR making use of two metrics one based on the Jacobian determinant and one on alterations in the Hounsfield unit (HU). Three various DIR regularization values (λ) were utilized for VICBCT. Correlations between the VICBCT and VICT values had been assessed utilizing voxel-wise Spearman's position correlation coefficient (r). In case of both metrics, the Jacobian-based VICBCT with a gantry speed of 0.6 deg/sec in Versa HD showed the highes
