Document Type and Number:
Japanese Patent JP2777155
Kind Code:
B2
Abstract:
A magnetic resonance imaging system collects all the data required for image reconstruction of a predetermined portion of an object (5) under examination by one excitation process in accordance with a pulse sequence in which, after excitation of spins within the predetermined portion by a radio frequency magnetic field and a gradient magnetic field, a predetermined readout gradient magnetic field is applied switched positive and negative at high speed to produce multiechoes on both sides of a spin echo center and a predetermined phase encoding gradient magnetic field is applied whose amount and sequence in encode steps are controlled so that multiecho data or its complex conjugate data may scan substantially the half of a Fourier data plane. By taking the complex conjugate of the magnetic resonance data collected in that way and then two-dimensional Fourier transforming the magnetic resonance data and the complex conjugate data, a magnetic resonance image of the predetermined portion of the object (5) is obtained.
