IDEAL-A fast single scan method for X pulse width calibration.
In line with the recent development of the rapid single scan technique to calibrate proton flip angle, a new method that allows calibration of X-nucleus pulse width in a single scan is presented. The method involves observation of the anti-phase coherence of a proton coupled to a hetero-nuclear X-spin with nutation pulses applied at the X-spin resonance frequency in a gated decoupling experiment. The X-spin nutation causes the well-known illusions of decoupling, enabling estimation of rf amplitude level and the method is, thus, dubbed as IDEAL.
