Learning Objectives: 

On successful completion of the course, students should be able to: In part A, students should demonstrate an understanding of the principles of magnetic resonance imaging (MRI) physics. The emphasis is not on the more advanced MRI techniques, but on the development of a solid understanding and application of the basics of image formation and spatial accuracy, image contrast clinical applications, and safety. In part B students should demonstrate an understanding of the principles of Ultrasound (US) imaging. Emphasis is on the application of the principles of acoustic physics, interaction of ultrasound with tissue, ultrasound transducers and arrays, and ultrasound imaging and Doppler instrumentation. Students in Part C should exhibit an understanding of basic laser biophysics and laser-tissue interaction. They should be able to explain how lasers work, and differentiate between the characteristics of lasers. They should be able to evaluate and apply the pertinent energy, optical and fiber concepts that are applicable to medical laser use. Discuss concepts of risk, including the evaluation of radiation risks, risk-benefit analysis, and index of harm. Apply methods to minimize dose to sites of risk such as the fetus, lenses and gonads.
