Abstract: Multi-slice selectable resolution NMR data acquisition in which multiple slice regions in an object are defined, and the slice regions are excited to emit NMR signals. The NMR signals are spatially encoded, and at least two selected slice regions are excited to emit NMR signals encoded with different spatial resolutions.

Abstract: An apparatus for obtaining, in the course of a single scan, NMR image data for a plurality of selected planes in an object, oriented at different angles, utilizes a slice pointer for outputting a signal indicating a particular plane to a multiplier and offset parameter RAM which provides multiplier and offset terms corresponding to the angle of the plane. A generator provides a generic gradient waveform to an arithmetic unit which combines this waveform with the multiplier and offset parameters from the RAM to create waveforms, which when applied to the gradient coils of an NMR apparatus, rotate the slice selector and the readout gradients, thereby permitting image data to be obtained in planes having different angles. A method in accordance with the apparatus of the present invention is also disclosed.

Abstract: A method for obtaining in the course of a single scan T1-weighted and T2-weighted NMR imaging data for a plurality of selected planes in an object using nuclear magnetic resonance techniques. The method is accomplished by positioning an object to be imaged in a static homogeneous magnetic field and then carrying out a plurality of repetitions of a repetition sequence composed of NMR excitation and magnetic field gradient pulses for a plurality of selected planes in the object. The repetition sequences for each of the selected planes include a combination of a T1-weighted pulse sequence having a TE.sub.1 and TR.sub.1 suitable for obtaining T1-weighted NMR imaging data and a T2-weighted pulse sequence having a TE.sub.2 and TR.sub.2 suitable for obtaining T2-weighted NMR imaging data. The repetition sequence for each selected plane is repeated a plurality of times and carried out in a manner so as to encode spatial information into the collection of NMR signals.
