FIELD: electronic equipment.
SUBSTANCE: use: for magnetic resonance (MR) tomography of object. Summary of invention consists in the fact that object is exposed to a visualizing sequence of RF pulses and switched magnetic field gradients, wherein the visualizing sequence is a zero-echo delay sequence comprising: I) adjustment of magnetic field reading gradient having reading direction and reading intensity (G1, G2); II) emitting a RF pulse in the presence of a magnetic field reading gradient; III) obtaining a FID signal in the presence of a magnetic field reading gradient, wherein the FID signal is a radial reading of the k-space, wherein obtaining the FID signal is started at the acquisition time, at which the gain of the receiver of the MR of the tomography has not yet stabilized after emitting the RF pulse; IV) gradual change of reading direction; V) sampling spherical volume in k-space by repeating steps I)–IV) several times. Finally, the MRT image is reconstructed from the obtained FID signals. Invention also relates to an MR tomography and a computer program for an MR tomography.
EFFECT: possibility of providing "noiseless" ZTE visualization with improved sampling of the central part of k-space.
