PHY214 Electromagnetism (8)
CSU Discipline Area: Medical Radiation Science (MEDRA)
Duration: One session
Abstract:
This subject covers the basic principles of electrostatics, dc and ac electricity, magnetism, electromagnetism and basic semiconductor electronics, as relevant to medical radiation science. The subject provides a foundation for the separate study of the design and operation of medical radiation equipment, and processes involved in image production and enhancement.
