MR Movies using Single Echo Acquisition Imaging
| Single Echo Acquisition (SEA) imaging uses an array of coils
to eliminate phase encoding.
As an example of the method, we have built a simple rotating phantom consisting of a "Lego" cross which rotates inside a dish. A small electric motor well outside the magnet controls the speed of the dish.

| On the right is a SEA image sequence. Each frame is obtained in 8 milliseconds. Note that there are no motion artifacts in this movie due to the short "aperture" of the SEA method. |
