Fundamental principles of Nuclear Magnetic Resonance (NMR)
Item no.: P5942100
The fundamental principles concerning the phenomenon of nuclear magnetic resonance (NMR) are demonstrated. Experiments are executed with a MRT training device giving the opportunity to investigate some small probes in the sample chamber. Investigations comprise the tuning of the system frequency to the Larmor frequency, the determination of the flip angle of the magnetisation vector, the effects of the substance quantity, the influence of particular magnetic field inhomogeneities, the measurement of a spin echo signal and an averaging procedure to maximise the signal-to-noise ratio. The adjustment of all parameters in these experiments are inevitable to obtain an adequate MR image in other experiments which can be performed with the same system without requiring any additional components.

Tasks

1. Tune the system frequency to the Larmor frequency
2. Set the HF (High Frequency) pulse duration to determine the flip angle of the magnetisation vector
3. Determine effects of the substance quantity on the FID signal (Free Induction Decay) amplitude
4. Minimise magnetic field inhomogeneities via a superimposed magnetic field (shim)
5. Retrieve a relaxated FID signal via a spin echo flipping nuclear spins by 180°
6. Improve the signal-to-noise ratio (SNR) of the FID signal
