Intensity modulated proton therapy.
Intensity modulated proton therapy (IMPT) implies the electromagnetic spatial control of well-circumscribed "pencil beams" of protons of variable energy and intensity. Proton pencil beams take advantage of the charged-particle Bragg peak-the characteristic peak of dose at the end of range-combined with the modulation of pencil beam variables to create target-local modulations in dose that achie...
متن کاملPrioritized efficiency optimization for intensity modulated proton therapy.
A high dosimetric quality and short treatment time are major goals in radiotherapy planning. Intensity modulated proton therapy (IMPT) plans obtain dose distributions of great conformity but often result in long delivery times which are typically not incorporated into the optimization process. We present an algorithm to optimize delivery efficiency of IMPT plans while maintaining plan quality, ...
متن کاملRecent Advances in Intensity Modulated Proton Therapy Treatment Planning Optimization
Radiation therapy is a non-invasive treatment modality for cancer patients. Radiation therapy treatment planning for cancer patients provides many challenging optimization problems. Various variables of a treatment plan need to be optimized so that the resulting plan can kill all cancerous cells while minimizing damage on the patient’s normal tissues. Intensity modulated proton therapy (IMPT) h...
متن کاملProton-Beam vs Intensity-Modulated Radiation Therapy
June 01, 2008 External-beam radiation is a highly effective curative treatment option for men with localized prostate cancer.[1,2] Over the past several decades, efforts have been made to improve the “therapeutic ratio” of radiation by increasing dose to improve cure rates without causing a substantial increase in side effects. Due to its potential to create superior dose distributions, proton ...
متن کاملProton Therapy Reduces Treatment- Related Toxicities for Patients with Nasopharyngeal Cancer: A Case-Match Control Study of Intensity-Modulated Proton Therapy and Intensity-Modulated Photon Therapy
Purpose: The physical properties of proton therapy allow for decreased dose delivery to nontarget structures. The purpose of this study was to determine if this translates into a clinical benefit by comparing acute and chronic morbidity between patients with nasopharyngeal carcinoma who are treated with intensity-modulated proton therapy (IMPT) and those treated with intensity-modulated radiati...
