Medical Imaging - What Diagnostic Scans Can Reveal

Medical imaging includes all of the non-invasive techniques used to create images of the human body for medical purposes. It is used to diagnose or monitor the progress of disease, and for medical science in the study of anatomy and physiology. Imaging techniques involve the detection of how different structures in the body, for example the brain, change or produce electromagnetic, sonographic or radioactive signals. The data collected is used to produce images of the structures under investigation. In this podcast, I will explain the physics behind these imaging techniques, with reference to their applications and limitations.
