Positron Emission Tomography
PET or Positron Emission Tomography is another 3D imaging technique for living organic beings. It produces a three-dimensional image or picture of functional processes in the body in a similar fashion to SPECT systems. Essentially, it slices the body into tens of thousands of slides using gamma rays. These can then be stacked together to create a 3D rendition.

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.
