Feasibility and constraints of Bragg peak FLASH proton therapy treatment planning

Frontiers in Oncology
IntroductionFLASH proton therapy (FLASH-PT) requires ultra-high dose rate (≥ 40 Gy/s) protons to be delivered in a short timescale whilst conforming to a patient-specific target. This study investigates the feasibility and constraints of Bragg peak FLASH-

The impact of breathing amplitude on dose homogeneity in intensity modulated proton therapy

Physics and Imaging in Radiation Oncology, 2017
Background/purpose: Intensity-modulated proton therapy (IMPT) dose distributions can be severely degraded in targets moving with respiration due to the interplay, range and blurring effects. In this study we investigated the joint and disentangled impact

Impact of heterogeneities on lateral penumbra in uniform scanning proton therapy [PDF]

, 2013
Purpose: In the treatment planning of uniform scanning proton therapy, an aperture block is designed for each beam with a margin, which typically includes the lateral penumbra measured in water (homogenous) medium.

Modern proton therapy in prostate cancer: precision in practice

Frontiers in Oncology
Proton therapy (PT) is an advanced form of radiation therapy that exploits the physical properties of the Bragg peak to deliver highly conformal dose distributions while minimizing radiation exposure to surrounding normal tissues.
