MRI Physics

Imagine seeing inside the body in vivid detail without ever making an incision, MRI physics makes this a reality. This course takes you into the core of Magnetic Resonance Imaging (MRI) technology, where magnets, radio waves, and protons align to create some of the most detailed medical images available. Covering everything from magnetic field fundamentals to advanced imaging techniques, you'll gain a deep understanding of how MRI works and how to optimize its use in medical diagnostics. Through each module, you'll dive into crucial topics like magnetic resonance, the role of gradient and RF.
