Effects of Single and Multiple Dose Tiotropium/Olodaterol in Chronic Obstructive Pulmonary Disease on Alveolar Gas Exchange Measured by Hyperpolarized 129Xe MRI

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Long‐acting muscarinic antagonists/long‐acting beta adrenoreceptor agonists lead to lung deflation and improved microvascular perfusion in hyperinflated chronic obstructive pulmonary disease (COPD), but with an unclear time course. Purpose To investigate the effect of inhalation of tiotropium/olodaterol (TIO/OLO) on MRI measures of ...

Design and Evaluation of Adaptive (Serial/Parallel) Concatenated Convolutional Codes

open access: yesJournal of Engineering and Sustainable Development, 2006
In this paper, parallel Concatenated Convolutional Codes (PCCCs) is modeled as a special case of Serial Concatenated Convolutional Code (SCCCs). Consequently, resulting in Adaptive (parallel/serial) concatenated convolutional code in which the same ...

Approaches to Computed Tomography Education for Radiography Students

open access: yesJournal of Medical Radiation Sciences, EarlyView.
The aim of this narrative review was to explore the current published literature relating to CT teaching methods and assessment of diagnostic radiography students during university training. Existing CT education evaluations focus on student satisfaction and usability of tools, with post‐lesson knowledge gains reported. Future work should shift towards

Ultra‐High Frequency Ultrasound Imaging and Quantification of Microvascular Flow in Xenograft Renal Cell Carcinoma in an Avian Chorioallantoic Membrane Model

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Patient‐derived xenograft (PDX) tumor models initiated in avian chorioallantoic membranes (CAM) are under investigation to evaluate the effectiveness of therapeutic options with the objective of personalizing treatments. CAM PDXs paired with ultra‐high frequency ultrasound (UHFUS) imaging could potentially constitute prospective high throughput assays ...

Interleaved Diffractive Networks for Information Transfer Through Random Diffusers

open access: yesLaser &Photonics Reviews, EarlyView.
This work presents a cascaded diffractive optical network that enables information transfer through random, unknown diffusers using passive, interleaved structured layers that mitigate scattering without digital computation. A hybrid optical‐digital version further improves robustness and reconstruction fidelity under distortions, with both simulations

Scalable Large Field‐of‐view 3D Photoacoustic Ultrasound Imaging With Digital Multiplexing for Human Extremities

open access: yesLaser &Photonics Reviews, EarlyView.
A digitally multiplexed, large‐aperture photoacoustic and ultrasound imaging architecture is presented to overcome the fundamental limited‐view artifact inherent in conventional arrays. By significantly broadening the structural detection coverage, this scalable platform enables high‐fidelity 3D visualization of human extremities within a single ...
