IRM

The video explains how MRI machines use powerful magnets to create images of the human body. It details the role of different magnets, including the main magnet and gradient magnets, and how they generate magnetic fields. The process involves aligning hydrogen atoms using radiofrequency pulses, which are then used to create images. The video also highlights the safety of MRI compared to X-rays, emphasizing the importance of avoiding metals near the machine.

What is the significance of the gradient magnets in an MRI system?

Describe the process that occurs when radiofrequency pulses are applied to the hydrogen atoms in the MRI machine.
