Quizplus · Accepted Answer

The imaging technique described involves taking X-rays from different angles aided by a computer, which is the process used in computed tomography (CT) scans. EEG involves recording electrical activity in the brain, MRI uses magnetic fields and radio waves to produce detailed images of the brain, and PET involves injecting a radioactive substance into the bloodstream to visualize brain activity.
