Signal-To-Noise Considerations In Reconstructive Nuclear Magnetic Resonance (NMR) Tomography

An equation which relates the signal-to-noise ratio (SNR) in a two dimensional NMR tomographic image to several basic image parameters is derived. These variables are the number of FID's averaged per view, number of views, pixel size and slice thickness. The theoretical equation was studied experimentally by varying one parameter at a time. Good agreement between experimental results and theoretical prediction was found.
