METHOD OF MAGNETIC RESONANCE IMAGING

摘要

This invention relates to a method of magnetic resonance ima-ging, includes following steps: sending a radio frequency ex-citation impulse to selection slice and putting a transverse magnetic field on a slice of three-dimensioned volume above; generating a first phase-encoding gradient impulse and a se-cond phase-encoding gradient impulse which sample k-space respectively; receiving a echo signal and a read out gra-dient, repeatly receiving the echo signals to form an echo train; modulating the phases of the echo signals in k-space so that the echo signals are essentially arranged in linear fashion according to phase discrepancy; then the image is re-constructed with Fourier transform. This invention can reduce artifacts of magnetic resonance imaging and improve the image quality.
