Magnetic Resonance Imaging
Magnetic resonance imaging or MRI is a type of medical imaging technology used to create 2D slide images of the human body, cut in cross section from any angle. The images are produced by the use of magnetic fields to align susceptible atoms in the body. This alignment is then manipulated to cause a pulsing effect that can be read by a magnetic sensor. Different body tissues pulsate at different frequencies, due to their atomic composition, creating the images.
