Magnetic Resonance Tomography

Magnetic Resonance Tomography or MRT is another name for Magnetic Resonance Imaging or MRI. The two terms refer to the exact same thing.

Magnetic resonance imaging 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.

Extra Sensory Perceptions: Sensing Magnetic Fields
The first known, successful implant of an extra sensory perception to detect magnetic fields the person with the new sense was near, occurred in 2005, when a small piece of neodymium, which is a rare earth metal, that forms a permanent magnet, was coated in a thin layer of silicon, and implanted into an emergency medical technician's finger.

Fast Adaptive Optics for 3D Medical Imaging
One of the greatest problems with tomography based medical scanners, is what happens when the patient moves (breathes, or pumps blood). The distortion that occurs in each slice has long been correctable, but takes a long time to correct. With near-instant correction now possible, real-time medical scanning is starting to look like a true possibility.
