1. Magnetic Resonance Imaging Sarah Ezzell Engr. 302

2. History NMR - 1930s Dr. Damadian “Tumor Detection by Nuclear Magnetic Resonance” - 1971 “Apparatus and Method for Detecting Cancer in Tissue” - 1974 Indomitable - 1977

3. Basics Magnetic field accompanied by radio-wave pulses What type of tissue are you?

4. Magnetic Field One of three magnet types: Permanent magnet Resistive magnet Superconducting magnet Gradient magnets

5. Creating an Image Hydrogen protons align with magnetic field RF pulse applied and terminated Excess energy released Picked up and sent to computer system

6. Advantages / Disadvantages Diagnosis / Evaluation Imaging planes Biological effects External objects Internal objects Claustrophobic Cost

7. Future Medical industry More compact, patient-friendly, less expensive Factory floor Fluid content analysis Measure of material hardness NMR Mouse Carpet manufacturing
