Beyond Antibiotics: Photo/Sonodynamic Approaches for Bacterial Theranostics
Nano-Micro Letters, 2020 Rapid evolution and propagation of multidrug resistance among bacterial pathogens are outpacing the development of new antibiotics, but antimicrobial photodynamic therapy (aPDT) provides an excellent alternative. This treatment depends on the interaction

A Quantum Mechanical Review of Magnetic Resonance Imaging [PDF]
arXiv, 2012 In this paper, we review the quantum mechanics of magnetic resonance imaging (MRI). We traverse its hierarchy of scales from the spin and orbital angular momentum of subatomic particles to the ensemble magnetization of tissue. And we review a number of modalities used in the assessment of acute ischemic stroke and traumatic brain injury.

Magnetic resonance imaging of the spine
Polish Journal of Radiology, 2020 Low back and neck pain are common and result in significant patient disability and health care expenditure. When conservative treatment fails or worrisome clinical findings are present, magnetic resonance imaging (MRI) is the imaging modality of choice to assess the cause and complicating features of spine pain.

Fast Multi-class Dictionaries Learning with Geometrical Directions in MRI Reconstruction [PDF]
arXiv, 2015 Objective: Improve the reconstructed image with fast and multi-class dictionaries learning when magnetic resonance imaging is accelerated by undersampling the k-space data. Methods: A fast orthogonal dictionary learning method is introduced into magnetic resonance image reconstruction to providing adaptive sparse representation of images.

Parallel Magnetic Resonance Imaging [PDF]
In: MRI: Physics, Image Reconstruction, and Analysis, CRC Press
2015, pp. 73-92, ISBN 9781482298871, 2015 The main disadvantage of Magnetic Resonance Imaging (MRI) are its long scan times and, in consequence, its sensitivity to motion. Exploiting the complementary information from multiple receive coils, parallel imaging is able to recover images from under-sampled k-space data and to accelerate the measurement.
