Comprehensive end‐to‐end dosimetry audit for stereotactic body radiotherapy in spine, lung, and soft tissue

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To create and conduct a comprehensive onsite end‐to‐end dosimetry audit to assess treatment accuracy of spine, lung, and soft tissue Stereotactic Body Radiotherapy (SBRT) across Australian and New Zealand (ANZ) radiotherapy centers. Methods The Australian Clinical Dosimetry Service (ACDS) anthropomorphic thorax phantom underwent a CT ...

Simulation‐free workflow for lattice radiation therapy using deep learning predicted synthetic computed tomography: A feasibility study

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Lattice radiation therapy (LRT) is a form of spatially fractionated radiation therapy that allows increased total dose delivery aiming for improved treatment response without an increase in toxicities, commonly utilized for palliation of bulky tumors.

Patient Selection in Deep Brain Stimulation: A Role for Transcranial Direct Current Stimulation to Enhance the Levodopa Challenge?

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Dopaminergic medication and deep brain stimulation (DBS) improve motor symptoms in Parkinson's disease (PD), but levodopa response alone may not predict DBS outcomes. We retrospectively analyzed 19 PD patients undergoing levodopa challenges with and without prior transcranial direct current stimulation targeting a defined PD response network ...

Precision‐Optimised Post‐Stroke Prognoses

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Current medicine cannot confidently predict who will recover from post‐stroke impairments. Researchers have sought to bridge this gap by treating the post‐stroke prognostic problem as a machine learning problem, reporting prediction error metrics across samples of patients whose outcomes are known.

Military Service Roles and ALS Among Veterans: A Matched Case–Control Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT While military service is an established risk factor for amyotrophic lateral sclerosis (ALS), it remains unclear whether this association is linked to combat. We conducted a matched case–control study comparing 191 ALS patients who were veterans of the Israeli Defense Forces (IDF) with known military service type and 1910 matched controls. The

Lattice Matched AlAs/GaAs/GaAs0.94Bi0.0583/GaAs0.91Bi0.0857 Multi-Junction Solar Cell with Optimized Thickness: A Theoretical Approach [PDF]

Journal of Electrical and Electronics Engineering, 2020
In this work we proposed a new four junction AlAs/GaAs/GaAs0.94Bi0.0583/GaAs0.91Bi0.0587 based solar cell, where AlAs (Eg=2.17eV) and GaAs0.91Bi0.0587 (Eg=0.7eV) were used as uppermost and bottom layer respectively.
