Sparse spokes slice selective design for B1 inhomogeneity correction at 7T
Introduction: At high magnetic field strength, B1 inhomogeneity causes undesired effects of non-uniformity in SNR and contrast. For slice selective excitation, 3D RF pulse design proposed in [1,2,3], can be used to mitigate this B1 inhomogeneity effect. These designs are based on playing kz sinc spokes of different amplitude at a number of (kx,ky) locations around the k-space origin. The sinc...
متن کاملAn Optimized Composite Refocusing Pulse for Ultra-High Field MRI
Purpose At high magnetic fields, the wavelengths of the RF pulses transmitted in MRI are comparable to the size of the human torso/head [1], which gives rise to inhomogeneous B1 fields. Variations of the RF field can be reduced (for example) by the use of tailored slice-selective pulses optimized for the desired excitation profile [2] based on spokes or an optimized composite pulse with slice s...
متن کاملComposite Localization with adiabatic slice selective excitation and refocusing (cLASER) for improved 1H MRSI in non uniform B1 fields
INTRODUCTION: H magnetic resonance spectroscopic imaging (MRSI) can be used as a diagnostic tool to distinguish abnormal from normal tissue by obtaining metabolic information which can be used as biomarkers. MRSI can be improved by going to higher field strengths like 7 Tesla which offer increased spectral resolution and SNR. However, at these field strengths the non uniformity of the B1 field ...
متن کاملHigh-flip-angle slice-selective parallel RF transmission with 8 channels at 7 T.
At high magnetic field, B(1)(+) non-uniformity causes undesired inhomogeneity in SNR and image contrast. Parallel RF transmission using tailored 3D k-space trajectory design has been shown to correct for this problem and produce highly uniform in-plane magnetization with good slice selection profile within a relatively short excitation duration. However, at large flip angles the excitation k-sp...
متن کاملComposite Slice-Selective 90' Excitation Pulses with Adiabaticity
Slice-selective adiabatic pulses are mostly confined to spin inversion and refocusing pulses. Here composite slice-selective 90" excitation pulses capable of multi-slice applications are proposed. This new class of pulses are based on halved adiabatic MIP pulses with each segment of the halved MIP pulses replaced by a small flip angle slice-selective plane rotation pulse such as a hamming-filte...
