Obstetric sonography has become an indispensable tool during pregnancy. This module teaches you how to prepare for and perform an ultrasound examination during the second and third trimesters. The interactive simulator provides three different scan scenarios that cover different aspects of the scan protocol. It enables students and practitioners to build or refresh knowledge and cognitive skills, and offers a safe online practice environment so you can prepare for the real clinical world. This module is ideal if you are studying for the American Registry for Diagnostic Medical Sonography (ARDMS) registry exams.
