Dense lung vasculature landmarking is vital for assessing thoracic registration accuracy in treatment planning. We demonstrate an automated method for identifying vascular bifurcations in free-breathing CT images.
Functional avoidance radiotherapy requires accurate regional lung ventilation mapping. Jacobian-based free-breathing ventilation derived from deformable image registration (DIR) of 4DCT is established but susceptible to inaccuracies caused by errors in the di...
Standard Cone-Beam CT (CBCT) has limited utility in longitudinal lung tumor response assessment due to the presence of motion artifacts. Our proposed method of motion-compensated Simultaneous Algebraic Reconstruction Technique (mcSART) addresses these artifac...
