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.
To commission Standard Imaging Exradin W1 scintillator detector (W1) on RefleXIon PET-Linac system for small-field dosimetry in both image-guided radiotherapy (IGRT) and biology-guided radiotherapy (BgRT).
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.
The next-generation PET-based SCINTIX® Biology-guided radiotherapy (BgRT) X2 platform incorporates a four-time PET widened field of view (WFOV) and an anchor-point-tracking delivery algorithm (currently in development). These advancements are intended to impr...
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).
