The aim of this project is to implement and benchmark the non-invasive workflow based on optical tracking and multi-modality imaging techniques.
During the pre-treatment surgery, there are small clips sutured on the sclera in the proximity of tumor lesion. The clips serve as a surrogate of a tumor and play a key role in preparation of a patient specific geometric model of the eye and the tumor used for optimization of proton therapy. Clips are further utilized prior to proton therapy, to ensure the accurate alignment of the tumor in relation to the treatment beam (through x-ray imaging of the clips). Modern imaging methods open up a possibility to create a geometrically accurate model representation of an eye and tumor. Optical tracking systems carry a potential to align treated eye to treatment beam without clips and the associated x-ray imaging.
