Using Emission Computed Tomography

To use the ECT method is to inject radioactive atoms into the person's bloodstream and have them circulated into the brain. The energy emitted is monitored by external devices that provide information about their concentration in the brain. Lastly, a mathematical model allows the data on radiation to be translated into information about brain processes.

This method allows researchers to analyze one's physiological process in ways other forms of brain imaging cannot, and more.
