Feasibility of 3D tracking and adaptation of VMAT based on VMAT-CT

Radiotherapy and Oncology, 2020
Local computed tomography (CT) reconstruction is achievable with portal images acquired during volumetric-modulated arc therapy (VMAT) delivery and was named as VMAT-CT. However, the application of VMAT-CT is limited because it has limited field of view and no density information.

Dosimetric Study Comparing 3D Conformal Radiotherapy (3D-CRT), Intensity Modulated Radiotherapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) in Hypofractionated One-Week Radiotherapy Regimen in Breast Cancer

Cureus, 2022
Introduction Recently, the one-week hypofractionated radiotherapy regimen (26 Gy in 5 fractions) for adjuvant breast radiotherapy has been shown to be non-inferior to other hypofractionated regimens (15-16 fractions).

Loss of vesicular dopamine release precedes tauopathy in degenerative dopaminergic neurons in a Drosophila model expressing human tau. [PDF]

, 2013
While a number of genome-wide association studies have identified microtubule-associated protein tau as a strong risk factor for Parkinson's disease (PD), little is known about the mechanism through which human tau can predispose an individual to this ...

Organ-specific low-dose assessment in pediatric radiotherapy using nanodot OSL and NTCP modeling: Application to medulloblastoma. [PDF]

J Appl Clin Med Phys
Abstract Background In pediatric radiotherapy, controlling low‐dose exposure is a major challenge, particularly in the treatment of medulloblastoma, where the long life expectancy of young patients makes optimization of radioprotection crucial. Purpose This study provides a comprehensive and quantitative assessment of low‐dose exposure to normal ...
