Comprehensive clinical evaluation of novel 4DCTâbased lung function imaging methods
Abstract Purpose Methods have been developed that apply image processing to 4DCTs to generate 4DCTâventilation/perfusion lung imaging. Traditional methods for 4DCTâventilation rely on HounsfieldâUnit (HU) densityâchange methods and suffer from poor numerical robustness while not providing 4DCTâperfusion data.

A Python package for fast GPUâbased proton pencil beam dose calculation
Abstract Purpose Openâsource GPUâbased Monte Carlo (MC) proton dose calculation algorithms provide high speed and unparalleled accuracy but can be complex to integrate with new applications and remain slower than GPUâbased pencil beam (PB) methods, which sacrifice some physical accuracy for subâsecond plan calculation.

Abstract Objective We measured clinical and quantitative MRI outcome measures in CMT1A to assess longâterm responsiveness, establish longitudinal validity and assess MRI as a bridging biomarker. Methods Twenty patients with CMT1A and 20 matched controls underwent MRI, myometry and clinical assessments up to four times over mean 4âyear followâup ...

Subthalamic Nucleus Oscillatory Characteristics in Meige, Cervical Dystonia and Generalized Dystonia
ABSTRACT Objective Deep brain stimulation offers a unique opportunity to record neural activity of the basal ganglia. While much work in dystonia has focused on the globus pallidus internus, expanding research to investigate subthalamic nucleus (STN) activity in various dystonia types is critical to provide a comprehensive understanding of dystonia ...

Mucus Physically Restricts Influenza A Viral Particle Access to the Epithelium
The infectious potential of respiratory viruses depends on their ability to navigate through a layer of mucus that serves as a protective barrier in the lung. It is demonstrated that influenza A virus penetration through mucus is significantly limited by the gel's internal microstructure and, to a lesser extent, by adhesive binding to mucin glycans ...
