## Abstract Magnetic resonance involves two coupled resonating systems: the spins and the tuned receiver coil. We simulate the spin system by an equivalent electrical resonator. An analysis of coupled resonators leads to a straightforward derivation of properties such as radiation damping, frequenc
## Abstract Inclusion of a frequencyโdependent tissue conductivity in the calculation of the magnetic resonance imaging signalโtoโnoise ratio is considered. The linear dependence of field strength described previously by Edelstein is preserved for frequencies up to โ60 MHz. At higher frequencies, t
## Abstract Moving average can be used to improve the signalโtoโnoise ratio of NMR kinetic studies. The method was tested on simulated spectra with timeโdependent intensities or peak positions. It was then applied to a series of __in vivo__ spectra, showing the pharmacological effect of heptaminol
The signal-to-noise ratio (SNR) is a major obstacle to system noise, and (b) closer coupling between the sample and achieving increased resolution in magnetic resonance microscopy the coil for improved receiver efficiency. These design constraints (MRM). The SNR considerations for MRM are presented,
The fundamental limit for NMR imaging is set by an intrinsic signal-to-noise ratio (SNR) for a particular combination of rf antenna and imaging subjects. The intrinsic SNR is the signal from a small volume of material in the sample competing with electrical noise from thermally generated, random noi
