Sonography Principles and Instrumentation

About

This ARDMS License Exam Preparation Course is conducted to prepare students to write the American Registry for Diagnostic Medical Sonographers (ARDMS) exam.

Sonography Principles and Instrumentation (SPI) focuses on the essential aspects of sonography principles, physics, and instrumentation needed to prepare for the Registry Credentialing Examination.

Although the learning emphasis is on clinical knowledge, some theory is covered specifically for Registry purposes and for which there is only minimal practical relevance. Students are expected to know and understand some common equations but mostly from a conceptual or relational aspect.
