1. A method of modifying a segmented image dataset for a region of a respiratory system to match the corresponding anatomy of a patient'"'"'s respiratory system, the method comprising:

  • (i) forming a respiratory-gated point cloud of data that demarcates anatomical features in a region of a patient'"'"'s respiratory system at one or more discrete phases within a respiration cycle of the patient,(ii) density filtering the respiratory-gated point cloud to reduce the number of duplicate data points in the respiratory-gated point cloud,(iii) classifying data points of the density filtered respiratory-gated point cloud according to anatomical points of reference in a segmented image dataset for the region of the patient'"'"'s respiratory system, and(iv) modifying the segmented image dataset to correspond to the classified data points in the density filtered respiratory-gated point cloud.
