The goal of the present work is to design slice-selective and broadband refocusing pulses which are tolerant against B1 deviations.
Here we show, depending on repetition time and paradigm design, slice-timing effects can significantly impair fMRI results and slice-timing correction methods can successfully compensate for these effects and therefore increase the robustness of the data analysis.
In this paper, an improved method of designing slice-multiplexed RF pulses is presented: component pulses which are optimized with simulated annealing for a specific rephasing are combined using Shinnar Le Roux methods.
The design of slice selective pulses for magnetic resonance imaging can be cast as an optimal control problem.
It is designed to slice through corrugated steel and sheet metal.
Over tulip-shaped glasses of tannic tea we bargain for Antioch's famous laurel-oil soaps and for knives designed to slice tomatoes.
By Sunday morning, 750 charges designed to slice through steel will be strapped in place up and down the sides of each tank.
Cables were suspended between these reinforced pylons, designed to slice into approaching high-speed craft and decapitate would-be suicide bombers before they reached their mark.
As The Economist went to press, no such bargain looked likely to materialise in time to prevent it coming into force on March 1st.The sequester was originally designed to slice $1.2 trillion from spending over a decade.
In the present novel design of slice-selective broadband refocusing pulses (S-BREBOP) this phase error is avoided.
The overall effect is that of a silver bullet, designed to slice through lazy plains and tangled ribbons of road alike.
