High spatial resolution multi-site EPR oximetry - The use of a convolution-based fitting method
JOURNAL OF MAGNETIC RESONANCE, 152(2), 247–258.
Contributors: O. Grinberg *, n & H. Swartz *
author keywords: EPR oximetry; multi-site EPR oximetry; tissue pO(2); convolution-based fitting
MeSH headings : Algorithms; Electron Spin Resonance Spectroscopy / methods; Oximetry / instrumentation; Oximetry / methods; Oxygen / metabolism; Tissue Distribution
TL;DR:
A new method to enhance the spatial resolution of multi-site electron paramagnetic resonance (EPR) oximetry is described, based on consecutive applications of magnetic field gradients with the same direction but with a different magnitude and uses a convolution-based fitting algorithm to derive Lorentzian EPR linewidths of each individual peak of the EPR spectrum.
