Catalog Description:
This course is an introduction to the theory and design of magnetic resonance imaging systems, with an emphasis on theory from a physics and electrical engineering perspective. Mathematical derivations of fundamental principles will be explored. Topics include image acquisition and reconstruction, mechanisms for image contrast and resolution, and an overview of system design including magnets, gradients, and radiofrequency coils.
