Spin-Echo MRI Using π/2 and π Hyperbolic Secant Pulses
Frequency-modulated (FM) pulses have practical advantages for spin-echo experiments, such as the ability to produce a broadband π rotation, with an inhomogeneous RF field. However, such use leads to a non-linear phase of the transverse magnetization, which is why FM pulses like the hyperbolic secant...
