Method for retrospectively gating NMR data.

摘要

NMR imaging data are acquired using a variable phase-encoding gradient. NMR non-imaging data are acquired using fixed phase-encoding, and motion data are derived from such NMR non-imaging data. Gating data are extracted from the motion data and used to select from the NMR imaging data to produce gated image data. The gated image data are used to produce a reconstructed image.
