Official code for the diaphragm tracking algorithm
Following the workflow depicted below:
- segmentDiaphragm.m performs diaphragm segmentation using the peak-exhale 4D-CT
- getDph3DShift.m computes the principal motion vector by rigid registration to the peak-inhale 4D-CT
- get2DDiaphragmModel.m forward projects the 3D diaphragm model to the 2D projection space
- trackDiaphragm_max.m tracks the diaphragm on each candidate 2D projection using a maximal gradient algorithm
- the Include directory contains code used as dependencies
