The course is provided in English. The first half of this course will focus on the fundamentals of DIRECT imaging systems, primarily ultrasound (US) and optical imaging (e.g., OCT). The second half will explore RECONSTRUCTIVE imaging modalities such as X-ray computed tomography (CT), positron emission tomography (PET) and magnetic resonance imaging (MRI). Fundamental imaging principles will be emphasized given the limited time, but some advanced applications will be discussed. The overall goal is to give you the fundamentals of medical imaging system so you can understand in some detail how these systems work. This is a HANDS-ON class. Almost all materials will be on the course web site. If you have a laptop or other computational device that runs MATLAB, please bring it to every class. We will organize each computational session by group. We expect the classroom sessions to be interactive. Each class will start by reviewing relevant materials on the course web site related to the imaging topic for that week. Questions related to formal material should be addressed during this period. Each student will pick up a related topic and present his/her idea in the final project (NOTES for presentation will be provided in the first class).

Calculus, Signals and Systems, Matlab (Optional)
