4DCTreg / LRME-4DCT

Lung Respiratory Motion Estimation

LRME-4DCT

code

MATLAB code for "Lung Respiratory Motion Estimation Based on Kalman Filtering and 4D CT Image Registration"

Dataset

DIR-lab dataset:https://www.dir-lab.com

POPI dataset: https://www.creatis.insa-lyon.fr/rio/popi-model?action=show&redirect=popi

Implemented details:

• 4D CT data should be downloaded from the above datasets before implementation.
• In order to speed up the code running speed, the observation value can be pre calculated by the isoPTV method [1].
• For POPI dataset, please start with the file /POPI_test/Registration_Kalman_POPI.m
