Aim and Objectives:

The aim of this course is to introduce student to the basic principles of nuclear medicine practices for both imaging and therapy. The students are expected to acquire a knowledge of the fundamental aspects of the structure of the nucleus, radioactive decay, nuclear reactions and the interaction of radiation and matter. The experimental techniques used (or developed) for nuclear physics purposes (logic circuits, gamma cameras, semiconductor detectors) are described and their influence on development of new technologies are discussed. The course deals with nuclear diagnostic methods to detect the transportation and transformation of chemical substances of biological and other systems and provide training to control and optimize advanced nuclear diagnostic equipment.
