Medical Imaging: Getting Under Your Skin

This is a very good lecture!

Sound, motion, and a bit of fury pulse through this dynamic investigation into several imaging techniques used to examine the human body. Physicist Paul Lyman immediately captures the attention of his audience with his entrance, bumping down the long flight of lecture-room stairs to the front of the room on his bicycle. He hops off, removes his helmet and plunges into the world of X rays, computer tomography (CT scan), nuclear magnetic resonance imaging (MRI), and ultrasound.
