DETERMINATION OF A MAGNETIC RESONANCE SYSTEM CONTROL SEQUENCE

摘要

PURPOSE: Determination of magnetic resonance system control sequence is provided to be used as not only EPI locus or spiral geometry structure but also spoke position geometry structure, radial geometry structure or free shape geometry structure. CONSTITUTION: Target magnetization (m) is detected. An energy distribution function (E(k)) in a k space is determined on the basis of the target magnetization. K space locus is determined by considering the energy distribution function in the k space. An infinite frequency pulse train for the k space locus is determined by radio frequency (RF) pulse optimization method. Fourier transform of the target magnetization is implemented to determine the energy distribution function in the k space.
