Abstract
A magnetic resonance imaging apparatus and method employ a magnet system (12) creating a temporally constant magnetic field through an examination region (14) in which at least a portion of an object to be imaged is placed. A radio frequency (RF) excitation system (24, 26) applies an RF excitation to a volume of interest of the object to be imaged, and a receiver system (32) detects and demodulates magnetic resonance data from the volume of interest. A magnetic field encoding system (20, 22, 40) applies encoding magnetic fields to provide spatial discrimination of magnetic resonance data from the volume of interest within a single radio frequency excitation period. The spatial encoding of the magnetic resonance signal data is performed and collected along a preselected k-space trajectory, the k-space trajectory covering a plurality of intersecting. planes or partial planes of k-space data.
