To assess the effectiveness of alignment and monitoring procedures, we performed a preliminary study on ocular fixation procedures. We also designed and built a model eye phantom to verify the dose distribution within the eye and its surrounding area. Finally, we compared our experimental results to treatment plan calculations done with EYEPLAN Proton Therapy Planning Program. This allowed us to develop an optimal treatment plan based on typical movement data and position uncertainties. This study precedes the commencement of a controlled trial of proton therapy for AMD patients at IUCF. |
