Abstract
Official abstract text for this publication.
The use of selective RF excitation is discussed. A spectrally selective, large tip angle RF pulse is used to detect a weak signal from a first chemical species. A non-selective, small tip angle pulse is used in measuring a signal from a second chemical species in exchange with the first chemical species. The acquired resonance data provides maybe used to measure the ratio of the spectrally distinct species in exchange.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for measuring a ratio of two or more spectrally distinct chemical species in exchange, the method comprising the steps of: generating a first RF excitation pulse that selectively tips a first chemical species by a first tip angle; quantifying the first chemical species based on resonance signals generated in response to the first RF excitation pulse; under equilibrium conditions between the first chemical species and a second chemical spec…
