Abstract

This unit presents an in‐depth discussion of the radiofrequency field, including how variations in the RF field will cause variations in image intensity that are independent of the physical spin density and the effect of slice select gradients.

Keywords: signal; Bloch equations; spatially varying RF excitation; two‐dimensional beam excitation
