Course goals
The goal of the course is to expose the students to the fundamental physical principles and instrumentation in ultrasonic imaging, Doppler flow measurements and Doppler imaging. Advantages and pitfalls of ultrasound relative to other competing imaging modalities will be addressed. Clinical applications will be stressed.

Grading Policies
Homework (2 sets): 30%, Mid-term: 30%, Final: 40%
Each homework assignment will contribute towards 15% of the final grade. Both mid-term and final exams will be take-home tests consisting of problems that may involve literature search, computation, and complex mathematical derivations as well as analyses. Mid-term exam and final exam will be assigned at the end of weeks 6 and 14 respectively. Solutions to the mid-term exam are in general due one week following assignment unless specified otherwise. Solutions to the final take-home are due on the date and time of the final exam, as specified in USC Schedule of Classes web-site.
