Medical imaging: Less is more
Klaas P. Pruessmann1
Abstract
The magnetic resonance imagers used in medicine fill rooms with their large-field magnets. But developments in ultra-low-field devices may give the doctor of tomorrow a more portable version.
Magnetic resonance imaging (MRI) systems are used extensively in the radiology departments of most hospitals. Recent years have seen impressive advances in the quality of the images that MRI produces, in part owing to the use of ever stronger magnetic fields.
- Klaas P. Pruessmann is at the Institute for Biomedical Engineering, ETH and University of Zurich, 8092 Zurich, Switzerland.
