The NMR/MRI Education System provides hands-on experience with nuclear magnetic resonance principles and magnetic resonance imaging techniques in an educational laboratory setting. This compact 0.15 Tesla system integrates a permanent magnet unit, RF electronics, spectrometer with pulse sequence generation, and Greenwaves analysis software to demonstrate fundamental NMR phenomena including relaxation times, chemical shifts, and basic imaging protocols.
The system includes industrial control computer with pulse sequence generator, direct digital frequency synthesis, analog-to-digital converter, and a 15 mm probe coil for sample analysis. Students can perform experiments on liquid samples using the provided test tubes, examining signal acquisition, data processing, and image reconstruction workflows common to research and clinical MRI systems. The integrated heating system and temperature control enable investigation of temperature-dependent NMR parameters.
How It Works
The system operates on nuclear magnetic resonance principles where atomic nuclei with non-zero spin (primarily ¹H protons) align with the 0.15 Tesla static magnetic field. The RF unit generates radiofrequency pulses at the Larmor frequency to tip nuclear spins away from equilibrium. When RF excitation ceases, nuclei precess back to alignment, emitting detectable RF signals that encode information about molecular environment and structure.
The pulse sequence generator controls timing of RF pulses and data acquisition windows. Direct digital frequency synthesis provides precise RF generation, while the analog-to-digital converter samples the induced signals in the 15 mm probe coil. Temperature control enables investigation of thermal effects on relaxation parameters and molecular motion.
For imaging applications, the system demonstrates basic MRI principles including signal localization and image reconstruction, though spatial encoding gradients are limited compared to clinical systems. The Greenwaves software processes acquired data, performs Fourier transforms, and displays spectra or reconstructed images.

Practical Tips
Perform reference sample measurements regularly to verify system stability and pulse calibration accuracy.
Why: Ensures consistent educational results and maintains measurement reproducibility across different experimental sessions.
Keep ferromagnetic objects at least one meter away from the magnet unit during operation and storage.
Why: Prevents magnetic field disturbances that can affect measurement quality and potentially damage system components.
Allow adequate temperature stabilization time before beginning precision measurements or student experiments.
Why: Temperature stability directly affects magnetic field homogeneity and signal reproducibility in NMR measurements.
Optimize sample volume and positioning within the 15 mm test tubes for maximum signal-to-noise ratio.
Why: Proper sample preparation ensures clear spectral features and effective demonstration of NMR principles to students.
Ensure students understand RF safety protocols and proper operation of the heating system components.
Why: Educational environments require clear safety procedures to prevent equipment damage and ensure student safety.
Check RF cable connections and probe positioning if signal quality degrades during experiments.
Why: Mechanical connections are common points of failure that can significantly impact measurement sensitivity.
