IntroductionRadiation-induced oxygen depletion in tissue is assumed as a contributor to the FLASH sparing effects. In this study, we simulated the heterogeneous oxygen depletion in the tissue surrounding the vessels and calculated the proton FLASH ef

Higher Dose Volumes May Be Better for Evaluating Radiation Pneumonitis in Lung Proton Therapy Patients Compared With Traditional Photon-Based Dose Constraints
Autor: Wendy B. Harris, PhD, Wei Zou, PhD, Chingyun Cheng, PhD, Varsha Jain, MD, PhD, Boon-Keng Kevin Teo, PhD, Lei Dong, PhD, Steven J. Feigenberg, MD, Abigail T. Berman, MD, MSCE, William P. Levin, MD, Keith A. Cengel, MD, PhD, Shannon E. O’Reilly, PhD
Publikováno v: Advances in Radiation Oncology, Vol 5, Iss 5, Pp 943-950 (2020)
Purpose: The dosimetric parameters used clinically to reduce the likelihood of radiation pneumonitis (RP) for lung cancer radiation therapy have traditionally been V20Gy ≤ 30% to 35% and mean lung dose ≤ 20 to 23 Gy; however, these parameters are

Background and Purpose: Radiation esophagitis is a clinically important toxicity seen with treatment for locally-advanced non-small cell lung cancer. There is considerable disagreement among prior studies in identifying predictors of radiation esopha

Publikováno v: Photochemistry and Photobiology. 99:814-825
Photodynamic therapy (PDT) has been used to treat malignant pleural mesothelioma. Current practice involves delivering light to a prescribed light fluence with a point source, monitored by eight isotropic detectors inside the pleural cavity. An infra
