A basic knowledge of ultrasound physics and instrumentation is vital to ensure the correct application of ultrasound.

A basic knowledge of ultrasound physics and instrumentation is vital to ensure the correct application of ultrasound. Understanding how images are generated will enable you to recognize artifacts and thus help to prevent misdiagnosis.

This module (2 of 2) follows on from Ultrasound Physics 1 and guides you through more ultrasound physics principles, including artifacts, bioeffects, Doppler, and hemodynamics. It contains many illustrations and animations to help you understand important concepts.

Ultrasound Physics 2 is suitable for all practitioners of ultrasound or anyone interested in learning about ultrasound physics. It is a valuable learning resource for anyone getting ready for the ARDMS Sonographic Principles and Instrumentation (SPI) Exam.

You’ll learn

more ultrasound physics terminology and definitions
how to identify and explain artifacts (reflection errors), and methods to minimize artifacts
the methods used to measure power, and the relationship between power and patient exposure
how ultrasound interacts with living tissues and methods to minimize bioeffects
how harmonics can be used in diagnostic medical sonography
about hemodynamics, including different flow types and forms of energy
about Doppler principles: Doppler effect, color Doppler, power Doppler, and spectral Doppler
about testing equipment performance and the importance of quality assurance and preventive maintenance
and much more (see Content tab for more detail)

The SIMTICS modules are all easy to use and web-based. This means they are available at any time as long as the learner has an internet connection. No special hardware or other equipment is required, other than a computer mouse for use in the simulations. Each of the SIMTICS modules covers one specific procedure or topic in detail. Each module contains:

an online simulation (available in Learn and Test modes)
descriptive text, which explains exactly how to perform that particular procedure including key terms and hyperlinks to references
2D images and a 3D model of applied anatomy for that particular topic
a step by step video demonstration by an expert
a quiz
a personal logbook that keeps track of all the modules the learner has studied and how long
