Explanation:

According to my research on studies conducted by various medical professionals, I can say that based on the information provided within the question Professor Kingston is most likely using a functional magnetic resonance imaging (MRI). This machine tracks the oxygen blood flow that is being activated within the brain, usually caused by different types of stimuli. Which in this case the stimuli would be online gambling, and Professor Kingston wants to see which parts light up during the functional MRI.
