High spatial resolution dosimetry for radioactive plaques used for radiotherapy of eye lesions

点击翻译按钮获取中文摘要

Melanoma and squamous cell carcinoma are the commonest ocular malignancies in adults. While plaque brachytherapy has delivered advances in ocular cancer management, significant challenges remain. These include post-treatment vision loss (due to over irradiation of vital structures, e.g. optic nerve), treatment failure (~10%) and an inability to treat large tumours (>8mm thick). This project aims to address these challenges through rigorous quality assurance and enhanced dosimetry planning.
