(a) Pulse sequence. (b) Spatial dependence of the inversion time tinversion and the value of wave vector q due to the frequency-swept radio frequency and gradient pulse pair. (c) Transverse magnetization profile after the diffusion encoding. (d) A soft pulse and a delay replacing the first π/2 pulse to convert the antiphase signal to in-phase in PHIP experiments. (e) PROJECT loop replacing the CPMG loop in order to eliminate J modulation.
