Method and System for Generating Magnetic Field Gradients for an NMR Imaging Machine

摘要

Disclosed is a gradient generator system arranged around a volume of interest of axis Oz. The system includes z-gradient coils of axis Oz; z-gradient tubes of axes parallel to the axis Oz including coils arranged in a ring outside the z-gradient coils; x-gradient coils and y-gradient coils of saddle shape arranged around the z-gradient coils; and x and y-gradient tubes of axes parallel to the axis Oz and situated in a ring outside the z-gradient coils, being interposed between the z-gradient tubes, with each of the x and y gradient tubes including coils.
