Course Overview
This course builds upon the concepts presented in the first level Sonography Physics 1 course. The main focus will be on Doppler imaging for diagnostic sonography, describing the underlying physics and instrumentation for the different Doppler imaging modes (Continuous Wave Doppler, Pulsed Wave Doppler, Colour, Power and tissue Dopper). In addition, the biological effects of ultrasound, and ultrasound safety will be presented. The course is specific to Sonography with an emphasis on conceptual understanding of the physical phenomena.

Learning Outcomes
Upon successful completion, the student will be able to:
- State the Doppler effect, its application to diagnostic sonography, and the variables which affect the velocity reading.
- Compare and contrast the differences between the different Doppler imaging techniques (CW Doppler, PW Doppler, Colour Doppler, Power and tissue Doppler), including their advantages and disadvantages.
- Describe the appearance and causes of Doppler artifacts.
- Describe the Nyquist limit and its relationship to aliasing of the Doppler signal.
- State the main biological effects of ultrasound imaging, namely thermal heating and cavitation and describe how these effects depend on the frequency of the ultrasound pulses used.
- Define and explain the significance of the various bio-effect indices (SATA, SATP, SPTA, SPTP) and the output display standards, TI (thermal index) and MI (mechanical index).
- Understand the AIUM and Health Canada statements on bioeffects and safety for diagnostic medical sonography.
- Use these guidelines to help implement ALARA.
