based on chemical shift information

Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Arrangements or instruments for measuring magnetic variables > involving magnetic resonance > using nuclear magnetic resonance [NMR] > NMR imaging systems > with selection of signal or spectra from particular regions of the volume, e.g. spectroscopy > based on chemical shift information

CPC:

Arrangements or instruments for measuring magnetic variables > involving magnetic resonance (medical aspects A61B5/055; magnetic resonance gyrometers G01C19/60) > using nuclear magnetic resonance [NMR] (G01R33/24, G01R33/62 take precedence) > NMR imaging systems > with selection of signals or spectra from particular regions of the volume, e.g. in vivo spectroscopy > based on chemical shift information

No child classifications to compare. This is a leaf node in both IPC and CPC.
