Acquisition of different modes and collection of patient-specific parameters at the bronchial bifurcation level

A: Different “SGRT + CBCT” modes. CBCT_ij, CBCT_ijk, and CBCT_ijkl meant that two, three, four sets of images were randomly selected from five CBCT image sets per patient, respectively. B: Patient-specific parameters at the bronchial bifurcation level
