Spatial encoding in MRI is conventionally achieved by the application of switchable linear fields. The general concept recently introduced PatLoc (Parallel Imaging Technique using Localized Gradients) to use nonlinear fields achieve spatial encoding. Relaxing requirement that must be may lead improved gradient performance or reduced peripheral nerve stimulation. In this work, a custom-built insert coil capable generating two independent quadratic was driven with high-performance amplifiers...
Purpose The gradient system transfer function (GSTF) has been used to describe the distorted k‐space trajectory for image reconstruction. purpose of this work was use GSTF determine pre‐emphasis an undistorted output and intended trajectory. Methods MR determined using only standard hardware without special equipment such as field probes or a camera. prediction in reconstruction waveform pre‐emphasis. As test sequences, gradient‐echo sequence with phase‐encoding modulation spiral read‐out...
Abstract Purpose PatLoc (Parallel Imaging Technique using Localized Gradients) accelerates imaging and introduces a resolution variation across the field-of-view. Higher-dimensional encoding employs more spatial magnetic fields (SEMs) than corresponding image dimensionality requires, e.g. by applying two quadratic linear to reconstruct 2D image. Images acquired with higher-dimensional single-shot trajectories can exhibit strong artifacts geometric distortions. In this work, source of these...
Purpose The gradient system transfer function (GSTF) characterizes the frequency behavior of a dynamic and can be used to correct non‐Cartesian k‐space trajectories. This study analyzes impact coil temperature 3T scanner on GSTF. Methods GSTF self‐ B 0 ‐cross‐terms were acquired for Siemens (Siemens Healthcare, Erlangen, Germany) using phantom‐based measurement technique. terms measured various states up 45°C. temperatures continuously utilizing 12 sensors which are integrated by vendor....
This work presents the early performance characteristics of an inside-out prostate nonlinear gradient (NLG). Diffusion-weighted imaging (DWI) could detect cancers non-invasively. However, it requires high b-values, which in turn require a pulse with long duration, increasing echo time. A longer time means lower SNR and contribution from short T2 components. NLG coil circumvents this issue by having amplitude within limited field view, applies to imaging.
Abstract A cylindrical head gradient insert for human imaging with non‐linear spatial encoding magnetic fields (SEMs) has been designed, optimized and successfully integrated a modified 3T clinical MR system. This PatLoc (parallel acquisition technique using localized gradients) SEM coil uses SEMs that resemble second‐order shim fields, but much higher amplitude as well the possibility rapid switching. work describes optimization of design measurement methods to characterize its SEMs,...
Prostate cancer remains the second leading killer of men, yet it is also a disease with high rate overtreatment. Diffusion-weighted imaging (DWI) has shown promise as reliable, grade-sensitive method, but limited by low image quality. Currently, DWI quality directly related to gradient amplitudes, since weak gradients must be compensated long echo times.We propose new type MRI accessory, an "inside-out" and nonlinear gradient, whose sole purpose deliver diffusion encoding region interest....

An MRI scanner is equipped with global shim systems for shimming one region of interest (ROI) only. However, it often fails to reach state-of-the-art when two isolated regions simultaneously, even though the two-area can be essential in scan scenarios, such as bilateral breasts or dyadic brains. To address these challenges, a hybrid active and passive local technique proposed simultaneously region-of-interest areas within whole FOV.
