Travelling wave NMR

In the February 19 2009 issue of Nature David Brunner and Klaas Pruessmann from ETH Zurich showed that by using travelling instead of standing radio-frequency waves to acquire MR images, it becomes possible to obtain high-quality images of larger parts of the body at once. More importantly from the perspective of a patient, even at 7T these superb images can be obtained without the need to have the receiver very close to the body, thereby limiting patient room. Actually, this kind of technique will even allow more space around the patient. A nice example of how thinking outside the box, and, according to the press release, a serendipitous event (a conventional MR image with fold-over artefacts) can trigger a new evolution in technology.
