Nuclear Medicine
Abstract:
Nuclear Medicine is a branch of medicine which uses radioactive isotopes in both the diagnosis and the treatment of human diseases. The usual procedure is to administer a small amount of radioactivity into the body of the patient, which is then directed to the organs under study, such as the bones, the gallbladder, the liver, the thyroid, the lungs, or the heart, etc., to determine if these organs are functioning properly and to identify any abnormalities in them. The corresponding photons emitted by the radioactive substance from the target areas are then captured by a gamma ray camera. Appropriate computer software then allows us to use the data from the camera to obtain reconstructed images of these organs. In my seminar, I will identify and discuss the radioactive substances currently used in nuclear medicine, explain the operation of SPECT and PET, and present a variety of images obtained from them. This seminar will also serve as a report on my past summer's graduate internship (Physics 578) with McDonough District Hospital jointly arranged by Dr. Yan N. Lwin, Emeritus Professor of Physics, and Dr. Mark S. Boley, Physics Chair.
