Ultra-high Field MRI of the Kidney
, 2023 The current literature on ultra-high field MRI of the kidneys indicates that kidney imaging can clearly benefit from a significant increase in field strength for anatomic, functional, and metabolic studies. However, many advantages are accompanied by numerous technical difficulties, including inhomogeneity of the static (B0) and radiofrequency (RF ...

Ultra-High Field Imaging of Human Visual Cognition
Annual Review of Vision Science, 2023 Functional magnetic resonance imaging (fMRI), the key methodology for mapping the functions of the human brain in a noninvasive manner, is limited by low temporal and spatial resolution. Recent advances in ultra-high field (UHF) fMRI provide a mesoscopic (i.e., submillimeter resolution) tool that allows us to probe laminar and columnar circuits ...

Ultra-high field imaging of the human medial temporal lobe
, 2023 Ultra-high field (UHF) imaging provides substantial benefits for the structural and functional investigation of the human medial temporal lobe. The medial temporal lobe is a complex system of many subregions that is critically involved in many cognitive ...

Numerical Investigation of the Temporal Contrast in ps-OPCPA with Compact Double BBO Arrangement
Applied Sciences, 2022 The picosecond optical parametric chirped pulse amplifier (ps-OPCPA) with double BBO arrangement can support the ultrabroad spectrum even under a relatively long pump pulse duration (∼100 ps).

Ultra-High-Field Magnetic Resonance Spectroscopy in Psychiatry [PDF]
Frontiers in Psychiatry, 2017 The advantages of ultra-high-field (UHF ≥ 7T) MR have been demonstrated in a variety of MR acquisition modalities. Magnetic resonance spectroscopy (MRS) can particularly benefit from substantial gains in signal-to-noise ratio (SNR) and spectral resolution at UHF, enabling the quantification of numerous metabolites, including glutamate, glutamine ...

Terawatt-Class Few-Cycle Short-Wave Infrared Vortex Laser
Ultrafast Science, 2023 As a driving source for many nonlinear vortex phenomena, such as the generation of isolated attosecond optical vortices, terahertz vortices, etc., terawatt-class few-cycle short-wave infrared vortex lasers are now attracting widespread attention. However,

Ultra-High-Field MR Imaging in Polymicrogyria and Epilepsy [PDF]
American Journal of Neuroradiology, 2014 Polymicrogyria is a malformation of cortical development that is often identified in children with epilepsy or delayed development. We investigated in vivo the potential of 7T imaging in characterizing polymicrogyria to determine whether additional features could be identified.Ten adult patients with polymicrogyria previously diagnosed by using 3T MR ...

Ultra high resolution fMRI at ultra-high field [PDF]
NeuroImage, 2012 In this short review article I will summarize the path we took over the years towards increasing the spatial resolution of fMRI. To fully capitalize on the fMRI technique, a better understanding of the origin of the hemodynamic signals, and what factors are governing their spatial control is necessary.
