Problem addressed

Nuclear Magnetic Resonance (NMR) signals acquired with phased array coils during spectrometry measurements or chemical shift imaging require complex post-processing to recombine and analyze them.

The conventional methods involve complex algorithms (high computing power required), tedious multiple steps dedicated to correction of phase and frequency shift, and manual analysis.

TECHNOLOGY

FID Modulus is a simple and efficient method to phase and align MR spectra, considering modulus of the free induction decay (FID) signals:

• improved correction of phase & frequency shift due to the sample movement, to the phase shift of coils, and to the magnetic field inhomogeneity,
• Easier and quicker identification of components of the sample without affecting noise-to-signal (S/N) ratio.
