Physics & Astronomy Colloquium at CSU Long Beach

The Role of Physics in Medicine:

Examples From X-Ray Computed Tomography

Michael McNitt-Gray
UCLA Radiology
Director of Biomedical Physics Graduate Program

Monday, October 5, 2015
11:15am - 12:30pm in PH2-126

While we normally think of the practice of medicine as being primarily a study of anatomy, biology and physiology, the role of physics in medicine has been steadily increasing. In this talk, we will describe how physical principles are being used to provide information necessary for the practice of medicine, especially in diagnostic imaging.
To illustrate this, the example of X-Ray Computed Tomography (CT) scanning will be examined. The first clinical X-ray CT exam occurred in October 1971 in the UK. In the 40+ years since then, there have been tremendous advances in CT technology that have led to a remarkable array of clinical applications, some of which must have been unimaginable to Hounsfield, Cormack and others who developed those early scanners. Some of these include: cardiac scans so fast that heart motion is negligible, scans so fast pediatric patients are scanned with little or no sedation, and nearly every Emergency Department has a CT scanner in it or nearby. In this talk we will discuss some of the recent developments in CT and the current role of medical physics in the clinical application of these techniques.

All Physics students & faculty should attend!
