Abstract:
A method of imaging an object using a magnetic field, the method comprising:(a) providing a magnetic resonance imaging device having a peak physical gradient strength G.sub.0 ;(b) determining a set of optimized orthogonal gradients of the magnetic field from a combination of three physical gradients, two of the physical orthogonal gradients having values of G.sub.0 and a third of the physical orthogonal gradients having a value -0.5G.sub.0 ;(c) applying a gradient waveform to the magnetic resonance imaging device to cause the magnetic resonance imaging device to form the magnetic field, the magnetic field having the optimized orthogonal gradients determined in step (b); and(d) using the magnetic field formed in step (c) to image the object.
