Abstract
An NMR imaging apparatus, wherein a 180.degree. RF pulse is applied shortly after the termination of the 90.degree. RF pulse, and wherein after such 180.degree. pulse application, to collection of spins and after collection of spins to dispersion of spins are sampled asymmetrically, whereby Fourier transformation takes place by interpolating missing data on a Fourier plane, and by operating on the data, image is accurately reconstructed. The novel pulse sequence improves the S/N ratio and reduces deterioration of images.
