DEFINITION

Classification: 600/410

Magnetic resonance imaging or spectroscopy:

(under subclass 407) Subject matter for detecting radiation wherein the means for detecting is a system which applies electromagnetic radiation matching the natural precessional frequency of the nucleus of an atom in a living body to create a likeness (i.e., an image) or to otherwise analyze

the condition of the body being medically evaluated.

(1) Note. The image creating or analyzing system (e.g., spectrometer, etc.) may be used for generating a tomos:graphic image or in any other way aiding in diagnostic analysis.

(2) Note. A system of this type was originally termed a nuclear magnetic resonance (NMR) system. Nuclear magnetic resonance is considered to encompass both magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS).
