Abstract
It is important to estimate rib cage motion quantitatively because lung deformation is caused by motion of the rib cage and diaphragm. In this paper, a patient-specific model of rib cage motion between inhalation and exhalation is proposed based on anatomical knowledge and rib cage kinematics. Time-series geometric changes in the patient-specific 3D rib cage configuration (including the ribs, spine, and sternum), which is segmented based on exhalation CT images, can be simulated using the proposed method. In addition, the validity of the proposed rib cage motion model was evaluated using inhalation and exhalation CT images.
