Mr imaging with sensitivity encoding in the readout direction |
摘要 |
A magnetic resonance imaging system acquires a final image of a selected field of view with a selected spatial resolution. A magnetic resonance imaging scanner ( 10 ) encodes and receives magnetic resonance samples in phase encode and readout directions using a plurality of receive coils ( 14 ). The encoding and receiving undersamples in the readout direction. A reconstruction processor ( 30 ) reconstructs magnetic resonance samples acquired by each of the plurality of receive coils ( 14 ) into a corresponding plurality of intermediate reconstructed images. Each intermediate reconstructed image has aliasing and in some aspects degraded high spatial frequency characteristics due to the reduced sampling in the readout direction. A combining processor ( 40 ) combines the plurality of intermediate reconstructed images based on coil sensitivity factors ( 42 ) to produce the final reconstructed image with the selected field of view and the selected spatial resolution in the readout direction.
