ABSTRACT:
Method for imaging the interior of a three dimensional object. A non-selective composite hard RF pulse is generated in the presence of a uniform magnetic field. Phase encoding pulses are generated along the first and a third axis, respectively, and a frequency encoding pulse comprised of a de-phasing portion and a re-phasing portion is generated along a second axis. During the re-phasing portion of the frequency encoding pulse, an asymmetrical fractional gradient echo containing information related to the object being imaged is produced. A next asymmetrical fractional gradient echo is then produced for next phase encoding pulses along the first and third axes. After an asymmetrical fractional gradient echo is produced for all phase encoding pulses, an image of the object is produced from the series of produced asymmetrical fractional gradient echoes.
