ABSTRACT:
A method for creating an image of in situ biological tissue uses an inhomogeneous field MRI device to pulse the tissue with sequential epochs of excitation pulses. Each epoch of excitation pulses includes, in order, an initial tilting pulse, an x-y encode and a train of refocussing pulses. Specifically, each x-y encode has a K-space identifier of the form i(1 . . . m)+j(1 . . . n), and the tilting pulses change sign according to whether the K-space identifier (i+j) is odd or even. For an image having m.times.n pixels, n.times.n epochs are used to generate n.times.n measurements of imageable spin echo signals. These m.times.n measurements are then collated to create the image.
