Medical imaging technologies-true marvels of medical science-give doctors the ability to analyze and interpret bodily anatomy and processes noninvasively. But how do ultrasound, hard and soft X-rays, CT scans, PET scans, and MRI scans create their remarkable images? This program thoroughly examines the physics of health-related imaging as it investigates the medical properties of electromagnetic and high-frequency sound waves. Detailed graphics appear throughout.
