SU‐FF‐T‐181: The Development of Eye Treatment Gating System for the Proton Therapy
Medical Physics, 2009Co-Authors: D Shin, Myonggeun Yoon, Y Lim, Duk-kyung Kim, Sung-ja Ahn, S.h. Lee, Sunwoo Park, Sunyoung MoonAbstract:Purpose:Proton therapy is suggested as a next generation radiation therapy with their great dose localization performance compared with linear accelerator. Although proton therapy is recommended for Eye Melanoma treatment due to its excellence in dose localization, the patient positioning system (PPS) is essential since small error in PPS may cause significant damage to the patient. In this study, we developed an automatic real time Eyeball tracking and gating system for the treatment of Eye Melanoma Method and Materials: A gating system was developed using Labview 8.6 software with GUI based development tool (National Instrument). The real time image for Eye movement was taken using CCDcamera, which was transferred to the homemade image analysis program. Using the Eye gating system, a real time Eye ball tracking based on image pattern matching method was realized by comparing a treatment template image used in the treatment planning with a real time image acquired from CCDcamera. And generating the gating control TTL trigger signal for the proton beam on and beam off . Results: Based on the real time image analysis system, we achieved the real time Eye ball tracking system with a resolution less than 0.01mm for the Eye ball movement which will be used for the treatment of ocular tumor in proton therapy, We can controlled the proton beam on and beam off with a time delay less than 0.1 sec for the Eye movement to over range for tolerance value. Conclusion:. We have developed Eye movement gating system for Eye treatmentproton therapy at our facility. The system will be use for Eye movement gated treatment for ocular patient.

Monte Carlo method to study the proton fluence for treatment planning
Medical physics, 1998Co-Authors: Harald PaganettiAbstract:The proton beam at the Hahn Meitner Institute (HMI) in Berlin will be used for proton therapy of Eye Melanoma in the near future. As part of the pre-therapeutic studies, Monte Carlo calculations have been performed to investigate the primary fluence distribution of the proton beam including the influence of scattering foils, range shifters, modulator wheels, and collimators. Any material in the beam path will modify the therapeutic beam because of energy loss,multiple scattering, range straggling, and nuclear reactions. The primary fluence information is a pre-requisite for most pencil-beam treatment planning algorithms. The measured beam penumbra has been used as one of the parameters to characterize a proton beam for further calculations in a treatment planning algorithm. However, this phenomenological quantity represents only indirect information about the properties of the proton beam. In this work, an alternative parameterization of the beam exiting the vacuum window of the accelerator, as well as the beam right in front of the patient collimator, is introduced. A beam is fully characterized if one knows (for instance from Monte Carlo simulations) the particle distribution in energy, position, and angle, i.e., the phase space distribution. Therefore, parameters derived from this distribution can provide an alternative input in treatment planning algorithms. In addition, the method of calculation is introduced as a tool to investigate the influence of modifications in the beam delivery system on the behavior of the therapeuticproton beam.
