MAGNETIC RESONANCE IMAGING |
摘要 |
Magnetic resonance imaging apparatus uses an array of at least two receive coils 4,5 to perform parallel processing to enable phase-encode gradients to be omitted during data collection, and restored during processing using parallel processing to further reduce patient time in the apparatus, pre-acquired reference data is used (modules 10, 11) to unfold the aliased target data in modules 8,9. In accordance with the invention, the unfolding is performed against a series of representations of the reference data, varied for translational rotational and coil loading errors, and the unfolded image is chosen as that having the minimum entropy. |
