| Definition: |
| |
energy pulse from atomic nucleus: the energy pulse released by an atomic nucleus exposed to high-frequency radiation in a magnetic field. It is used to provide data about the atom that can be transformed into an image by computer techniques. This phenomenon is the basis of devices used in medicine, where it is called magnetic resonance imaging, to produce images of tissues, and in physics and chemistry to study molecular structure.
