Development of a Comprehensive, Contour-Based, Peer Review Workflow at a Community Proton Center [PDF]

International Journal of Particle Therapy, 2020
Purpose: Quality assurance and continuing quality improvement are integral parts of any radiation oncology practice. With increasingly conformal radiation treatments, it has become critical to focus on every slice of the target contour to ensure adequate

Clinical commissioning of intensity modulated proton therapy systems: Report of AAPM Task Group 185.

Medical Physics (Lancaster), 2020
Proton therapy is an expanding radiotherapy modality in the United States and worldwide. With the number of proton therapy centers treating patients increasing, so does the need for consistent, high-quality clinical commissioning practices.

Comparative clinical evaluation of atlas and deep-learning-based auto-segmentation of organ structures in liver cancer

Radiation Oncology, 2019
Background Accurate and standardized descriptions of organs at risk (OARs) are essential in radiation therapy for treatment planning and evaluation. Traditionally, physicians have contoured patient images manually, which, is time-consuming and subject to

Dosimetric evidence confirms computational model for magnetic field induced dose distortions of therapeutic proton beams

, 2017
Given the sensitivity of proton therapy to anatomical variations, this cancer treatment modality is expected to benefit greatly from integration with magnetic resonance (MR) imaging.

Proton therapy delivery: What is needed in the next ten years?

British Journal of Radiology, 2020
Proton radiation therapy has been used clinically since 1952, and major advancements in the last 10 years have helped establish protons as a major clinical modality in the cancer-fighting arsenal.

Dosimetric analysis of local failures in skull-base chordoma and chondrosarcoma following pencil beam scanning proton therapy

Radiation Oncology, 2020
Background Despite combined modality treatment involving surgery and radiotherapy, a relevant proportion of skull-base chordoma and chondrosarcoma patients develop a local recurrence (LR).

Treatment planning optimisation in proton therapy [PDF]

, 2013
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.

Temporal Lobe Necrosis in Head and Neck Cancer Patients after Proton Therapy to the Skull Base

International Journal of Particle Therapy, 2020
Purpose: To demonstrate temporal lobe necrosis (TLN) rate and clinical/dose-volume factors associated with TLN in radiation-naïve patients with head and neck cancer treated with proton therapy where the field of radiation involved the skull base ...

An ion-independent phenomenological relative biological effectiveness (RBE) model for proton therapy [PDF]

arXiv, 2022
Background: A relative biological effectiveness (RBE) of 1.1 is used for proton therapy though clinical evidence of varying RBE was raised. Clinical studies on RBE variability have been conducted for decades for carbon radiation, which could advance the understanding of the clinical proton RBE given an ion-independent RBE model.
