A New Quality Control System for Detecting Defects in Proton Range Modifiers for Proton Therapy
A NEW QUALITY CONTROL SYSTEM FOR DETECTING DEFECTS IN PROTON RANGE MODIFIERS FOR PROTON THERAPY Brad Kreydick, B.S. Department of Physics Northern Illinois University, 2013 George Coutrakon, Ph.D., Director Proton beam radiotherapy is an increasingly common and accepted form of cancer treatment, which utilizes the novel energy-deposition characteristics of heavy, charged particles to destroy tu...
متن کاملProton range verification in inhomogeneous tissue: Treatment planning system vs. measurement vs. Monte Carlo simulation
In particle radiotherapy, range uncertainty is an important issue that needs to be overcome. Because high-dose conformality can be achieved using a particle beam, a small uncertainty can affect tumor control or cause normal-tissue complications. From this perspective, the treatment planning system (TPS) must be accurate. However, there is a well-known inaccuracy regarding dose computation in he...
متن کاملA new model for Spread Out Bragg Peak in proton therapy of uveal melanoma
In this research, in order to improve our calculations in treatment planning for proton radiotherapy of ocular melanoma, we improved our human eye phantom planning system in GEANT4 toolkit. Different analytical models have investigated the creating of Spread Out Bragg Peak (SOBP) in the tumor area. Bortfeld’s model is one of the most important analytical methods. Using convolution method, a new...
متن کاملTreatment planning optimisation in proton therapy.
The goal of radiotherapy is to achieve uniform target coverage while sparing normal tissue. In proton therapy, the same sources of geometric uncertainty are present as in conventional radiotherapy. However, an important and fundamental difference in proton therapy is that protons have a finite range, highly dependent on the electron density of the material they are traversing, resulting in a st...
متن کاملIn vivo proton beam range verification using spine MRI changes.
PURPOSE In proton therapy, uncertainty in the location of the distal dose edge can lead to cautious treatment plans that reduce the dosimetric advantage of protons. After radiation exposure, vertebral bone marrow undergoes fatty replacement that is visible on magnetic resonance imaging (MRI). This presents an exciting opportunity to observe radiation dose distribution in vivo. We used quantitat...
