MRI exploiting frequency-modulated pulses and their nonlinear phase
Journal of Magnetic Resonance(2020)
摘要
•MRI has been slow to adopt frequency-modulated pulses despite their advantages.•Frequency-modulated pulses offer extreme robustness to nonuniform magnetic fields.•Tailored frequency-modulated pulses provide immense experimental flexibility.•Nonlinear gradients compensate for nonlinear phase of frequency-modulated pulses.
