A Method for Designing Optimum MRI Pulse Sequences for Imaging Oblique Planes
Straightforward method to calculate maximum gradient amplitudes for the functions of frequency encode, phase encode, and section select in oblique MRI. The calculated amplitude values depend on the angulation of the prescription, and on which of the three functions are simultaneously active. The derived expressions are optimal in most cases, and when not optimal still offer substantial improvement compared to calculations that do not incorporate angular information. Both matrix-based and geometrical interpretations are presented.
