Validation of an automatic eye monitoring system for ocular tumours stereotactic radiotherapy

Abstract Choroidal melanoma is a type of tumour that appears in the back of the eye and can rapidly evolve into metastasis. For tumours in advanced stages and/or located near the retina, external beam radiotherapy (teletherapy) is the most used treatment to preserve the patient's eye. The goals of this work are to develop a software for monitoring the patient's eye during the treatment, in order to detect dislocation that could irradiate volumes outside the planned target. and to check the system with a mechanical eye simulator with controlled movements. The results have attested the accuracy and reproducibility of the system, validating the software.
