Foundational knowledge of the cardiovascular system, in the context of ultrasound, is paramount before detailed discussions can begin in the echocardiography and vascular ultrasound courses. This course will discuss the anatomy and interconnectedness of the cardiovascular system and the hemodynamic principles involved. Specific calculations and ultrasound measurements used in the evaluation of the cardiovascular system will be summarized. The laboratory component of this course will focus on the operation of ultrasound controls for different imaging modes.
