Abstract:
A magnetic resonance imaging apparatus comprising:a main magnet for generating a main magnetic field through and surrounding an examination region;a gradient coil assembly for generating gradient magnetic fields across the examination region, the gradient coil assembly comprising:at least a first primary gradient coil set and a second primary gradient coil set disposed in an overlapping relationship, the first primary gradient coil being at least one of axially and radially displaced relative to the second primary gradient coil set by a displacement that minimizes mutual inductance between the at least two gradient coil sets;an RF transmitter, receiver, and coil assembly positioned adjacent the examination region such that it excites magnetic resonance dipoles in and adjacent the examination region and receives and demodulates magnetic resonance signals from the resonating dipoles; anda reconstruction processor for reconstructing the demodulated magnetic resonance signals into an image representation.
