On the accuracy of Monte Carlo based beam dynamics models for the degrader in proton therapy facilities

, 2018
In a cyclotron-based proton therapy facility, the energy changes are performed by means of a degrader of variable thickness. The interaction of the proton beam with the degrader creates energy tails and increases the beam emittance.

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

Radiation Therapy Medical Physics Review – Delivery, Interactions, Safety, Feasibility, and Head to Head Comparisons of the Leading Radiation Therapy Techniques [PDF]

, 2017
Radiation therapy uses high energy radiation to kill cancer cells. Radiation therapy for cancer treatment can take the form of photon therapy (using x-rays and gamma rays), or charged particle therapy including proton therapy and electron therapy. Within

Local treatment failure after globe-conserving therapy for choroidal melanoma. [PDF]

, 2013
Local treatment failure after globe-conserving therapy for choroidal melanoma is a surgical complication with significant morbidity to the vision and eye. Few reports in the literature have addressed this complication exclusively.

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

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
