Abstract

A straightforward method for calculating maximum gradient amplitudes for the frequency-encoding, phase-encoding, and section-select functions in oblique magnetic resonance (MR) imaging is presented. The calculated amplitude values depend on the prescribed angulation and on which of the three functions are simultaneously active. The derived expressions are optimal in most cases, and when not optimal, they still offer substantial improvement over calculations that do not incorporate angular information. Both matrix-based and geometric interpretations are presented.
