Abstract
A nuclear magnetic resonance imaging method in which the time necessary for forming a two-dimensional image of a single plane of a sample is significantly reduced, making the method applicable for imaging of the human heart or the like. First, nuclear spin is excited in a given volume of a sample disposed in a magnetostatic field. Secondly, first, second and third oblique magnetic fields are applied to the volume. Thirdly, the nuclear spin is rephased under the second magnetic field gradient by applying a 180.degree. pulse. Fourthly, the nuclear spin is phase modulated in the direction of the third magnetic field gradient prior to or following read out of a spin echo signal derived from the rephasing of the spin. Fifthly, the first through fourth steps are repeated, wherein the third magnetic field gradient in each of the repetitions of the fourth step has a constant absolute value and the direction of the third magnetic field gradient alternates.
