MRI Machines

An MRI (Magnetic Resonance Imaging) machine is a powerful medical imaging tool that uses a magnetic field and radio waves to create detailed images of the inside of the body. It is widely used to diagnose and monitor a variety of medical conditions, including injuries, tumors, and diseases.

How MRI Machines Work

When a patient enters the MRI machine, they are exposed to a strong magnetic field, which causes the hydrogen atoms in their body to align in a particular direction. Radio waves are then used to temporarily disrupt this alignment, and when the radio waves are turned off, the hydrogen atoms realign and emit signals that are captured by the MRI machine. These signals are used to create detailed cross-sectional images of the body.
