In 1998, IUCF constructed an eye treatment clinic, and conducted a phase III clinical trial investigating proton radiation treatment of AMD. Treatment was planned using Eyeplan modified to match the IUCF beam characteristics. MPRI was conceptualized. Numerous dose calculation algorithms for treatment planning with protons take as a basis an analytical description of the proton energy deposition: among these EYEPLAN today the most widely used ocular proton treatment planning system.

Comprised of both online and in-person training sessions, participants will have the opportunity to learn key clinical concepts firsthand from proton therapy experts. The program will cover all aspects of proton therapy, from patient selection and planning through treatment and follow-up. Learn more about the program. Currently, for all ocular melanoma patients being treated with proton beam, we use EYEPLAN[8] software for the treatment planning of these patients. The technique is based upon the ocular oncologist suturing four to five tantalum markers on the surface of the sclera in order to delineate the tumor base. The primary advantage of proton therapy compared with other types of external beam therapy is the ability to more precisely localize the radiation dose within the patient's body, thereby sparing healthy tissue and reducing the risk of secondary tumors. Philips Pinnacle³ Proton Planning has been designed to meet the. The use of MRI technology is potentially of interest to ocular proton RT centers, however there are significant challenges to implementation into the major current model-based eye planning software (EYEPLAN® TPS). MRI offers (I) potential confirmation of surgical tantalum clip placement in relation to tumor and eye,. EYEPLAN requires the axial eye length, membrane dimensions, and manipulation of the eye to include a 4.0-mm radial margin around the membrane so that the aperture margin (50% isodose line on the posterior retina) abuts the inferior aspect of the limbus. Review of 100 individually prepared plans showed that 95% of. Monte Carlo validation of EYEPLAN proton therapy treatment planning.

Patient treatments and dose distribution were planned using EYEPLAN V3.05.16 This version. no treatment planning was performed and no radiation was administered. Eye and tumor are reconstructed by the EYEPLAN treatment planning system that provides a correct proton dose distributions and eye position during the treatment. Before the treatment starts, the patient is immobilized. First of all, a fixation device is made by means of a customized thermoplastic mask and. eated by the ocular oncologist and verified by the radiation oncolo- gist. Treatment is planned by use of EYEPLAN software, developed originally by Goitein and Miller [13] for dosimetric calculations. A margin of 2.5 mm around the tumor edges is added to the planning target volume, and a brass collimator. The results were transferred to the EYEPLAN eye planning program (Harvard, MA) with our modifications (M. Sheen, CCO,. Wirral, UK), with further information on ocular features such as eye length, scleral thickness, limbus, and tantalum marker posi- tions with respect to tumor margins and limbus.
