Nonuniform and multidimensional Shinnar-Le Roux RF pulse design method.
The Shinnar-Le Roux (SLR) radiofrequency (RF) pulse design algorithm is widely used for designing slice-selective RF pulses due to its intuitiveness, optimality, and speed. SLR is limited, however, in that it is only capable of designing one-dimensional pulses played along constant gradients. We present a nonuniform SLR RF pulse design framework that extends most of the capabilities of classica...

متن کاملDesign of Velocity Selective Inversion Pulse for VSASL using the Shinnar-Le Roux Algorithm
Introduction: The tagging pulses in Velocity Selective Arterial Spin Labelling (VSASL) [1] are purely Velocity-Selective (VS), rendering VSASL potentially resistant to transit delay effects and suitable for use in cases with slow blood flow. Many different approaches have been used to design VS pulses [1-4], including saturations and inversions. Here we propose a method to improve the velocity ...
متن کاملDesign of high-bandwidth adiabatic RF pulses using the Shinnar Le-Roux algorithm
Introduction: Adiabatic pulses are a special class of RF pulses that provide B1-insensitive rotation of the magnetization. When utilizing adiabatic pulses, particularly at high magnetic fields, low-SAR pulse designs are highly desirable. In this work, we present a new, systematic method for designing high-bandwidth, low-peak-amplitude adiabatic pulses by using the Shinnar Le-Roux (SLR) algorith...
متن کامل|B1(+)|-selective excitation pulse design using the Shinnar-Le Roux algorithm.
A new mathematical treatment and algorithm for the design of |B1(+)|-selective RF excitation pulses is presented and validated. The algorithm is based on a rotated Shinnar-Le Roux pulse design algorithm, wherein the pulse's frequency modulation waveform is directly designed by the algorithm, and its amplitude and sign modulation waveform takes the place of the gradient field. A new pulse config...
