Ultrasound Physics and Machine settings

Lecture Overview (Ultrasound physics)

This lecture delivers a clear and simplified explanation of ultrasound physics and echocardiography machine settings, covering everything from the fundamentals of ultrasound waves to how echo images are formed. It explains the relationship between frequency, resolution, and penetration, and highlights the importance of staying within safe scanning limits.

The session also provides an easy breakdown of imaging modes (A-mode, B-mode, and M-mode), along with a strong introduction to Doppler echocardiography, including PW vs CW Doppler, aliasing, and color Doppler interpretation. Finally, it summarizes the most important machine adjustments such as gain, TGC, frequency, depth, focus, zoom, and dynamic range, helping learners understand how to optimize image quality in real clinical practice.
