Method and circuit for operating a magnetic resonance imaging apparatus for producing tomograms in an arbitrary position |
摘要 |
A method and circuit for operating a magnetic resonance imaging apparatus to produce tomograms in an arbitrary position (plane) generate logic gradients which are arbitrarily spatially oriented by a combination of a number of physical magnetic field gradients. At least one gradient coil is operated in a resonant circuit. The logic gradients do not chronologically overlap. A logic read-out gradient can have gaps (non-signal regions) in the region of its zero-axis crossings, at which time a logic phase-coding gradient can be activated.
