In image-guided radiation therapy (IGRT), patient positioning is typically estimated by rigid registration between cone-beam CT (CBCT)–derived digitally reconstructed radiographs (DRRs) and treatment kV X-ray images acquired at the same gantry angle. However,...
To investigate the feasibility of three-dimensional fiducial localization using small-angle kV image pairs from adjacent projections as a time-efficient alternative to conventional orthogonal imaging, and to determine the minimum gantry angle separation.
This study aims to quantitatively evaluate intrafraction target motion through post-treatment analysis based on offset-dependent three-dimensional reconstruction of on-treatment kV images.
This study aims to quantitatively evaluate the three-dimensional positional fidelity of implanted fiducial markers in deep learning-based sparse-view reconstruction from on-treatment kV images acquired during prostate stereotactic body radiotherapy (SBRT).
