Abstract
A pair of quadrature radio frequency coils ( ) disposed adjacent an imaging region ( ) are typically loaded differently due to factors such as subject geometry, subject mass, and a relative distance from the subject. A tip angle adjustment circuit ( ) monitors a combined tip angle adjacent a mid-plane of the examination region, such as by analyzing delivered and reflected power to each of the coils. An adjustment circuit ( ) adjusts relative RF power or amplitude to produce a selected, combined tip angle in the examination region.
