  • Magnetic resonance angiography by sequential multiple thin slab three dimensional acquisition
    Patent number: 5167232
    Abstract: A method for acquiring image data for three dimensional magnetic resonance angiography using magnitude contrast, ("time-of-flight") imaging techniques allowing for the arbitrary offset of a slab or slabs in a sample, and allowing for the acquisition of multiple thin overlapping slabs using the steps of: selecting an image area on a sample as a one or more thin slabs; applying magnetic gradients to a sample in a logical x, y, and z coordinate system by use of a magetic resonance apparatus; applying radio frequency pulses to the image area within the sample; shifting the slab or slabs (overlapping the slab image area) by rotating the radio frequency pulse for the shifted (overlapping) slab or slabs.

  • NMR imaging method
    Patent number: 4583044
    Abstract: NMR images are resolved from FID signal data generated under asymmetric conditions. Subtraction NMR images are resolved from corresponding signal data generated under both symmetric and asymmetric conditions.
