First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Fast Localized Calibration for Spatial‐Spectral Excitation Without Fly‐Back Gradients
ABSTRACT Purpose Standard spatial‐spectral excitation pulses apply a fly‐back gradient between sub‐pulses, limiting, for example, how thin the slices can be (> 4 mm). Without fly‐back gradients, slices can be as thin as 1.7 mm but require a phase calibration for the sub‐pulses with inverted gradients due to system imperfections.

ABSTRACT Purpose To jointly reconstruct high‐resolution diffusion‐weighted volumes and eliminate slab‐boundary artifacts while preserving fine anatomical detail from undersampled 3D multi‐slab k‐space acquisitions. Methods A bilinear forward model was formulated to describe the 3D multi‐slab acquisition, treating the image volume and slab excitation ...

ABSTRACT Purpose The design of radiofrequency (RF) coils tailored for the target anatomy is necessary to overcome the transmit field homogeneity and penetration issues at Ultra‐High‐Field (UHF). For the spinal cord, the optimal design has not yet been determined. This work intends to demonstrate the added value of a pair of passive dipoles placed under

In Vivo 31P‐MRS of the Human Orthotopic Kidney at 3 Tesla
31P‐MRS of healthy human orthotopic kidneys at 3T yielded improved spectral quality within a clinically feasible scan time. The resulting summed spectrum characterizes normal renal phosphorus metabolism and may serve as a reference for detecting metabolic alterations associated with kidney disease and transplantation.
