Episcleral plaque brachytherapy is the standard eye-preserving treatment for medium-sized ocular melanoma (OM), yet dosimetric evaluation remains challenging due to steep dose gradients, plaque curvature, and anisotropic source geometry. This study presents a...

Ablative hypofractionated radiotherapy(AHRT), including stereotactic body radiotherapy(SBRT) and stereotactic radiosurgery(SRS), achieves tumor control that is not reliably predicted by Linear–Quadratic (LQ) model. Clinical observations of failure of BED equi...

Image Guided Brachytherapy (IGBT) in a dedicated suite allows applicator placement, planning and treatment delivery in a single room, minimizing the patient movement during the process. The design and shielding considerations for the new IGBT suite are presen...
