Abstract
A method of deriving image formation from an object using nuclear magnetic resonance signals comprises the steps of subjecting an object to a static magnetic field along one axis, applying a first gradient to said magnetic field which varies in a direction orthogonal to said axis together with a 90.degree. high frequency pulse, reversing the direction of said magnetic field gradient and simultaneously applying a gradient to said magnetic field which varies in a direction parallel to said one axis and then reversing the direction of said last-mentioned gradient and reading out the free induction signal from said object.
