intra-subject respiratory motion; B-spline transformation
The sample CT dataset is available for download.
Registration of intra-patient thoracic CT scans in the presence of respiratory motion causing compression/expansion of lung parenchyma

elastix version: 4.9
The SumSquaredTissueVolumeDifference metric was implemented in
elastix during the course of this work.
Command line call:
elastix -p par0054_sstvd.txt -f scan_inhale.mhd -m scan_exhale.mhd -out ./output
Registrations using the SSTVD metric in
elastix were used in the following publication (corresponding to registration 1 in table 1):
