Beam Intensity and Bioeffects
Beam Intensity and Bioeffects
This lesson explains beam intensity in ultrasound, defined as power divided by cross-sectional area and measured in watts per centimeter squared. It covers the beam uniformity coefficient (SPSA factor), spatial and temporal intensity variations, and how these concepts relate to bioeffects and patient safety.

27:54 lessonHello and welcome to Prep's ultrasound Physics Registry Review course. I'm Jenna la Care, an AR DMS certified sonographer and your guide through the exciting journey of ultrasound physics. Recall that intensity describes how strong or intense or sound beam is. This is relevant to the concentration of energy in the beam. Intensity is calculated by dividing the beam's power by its cross-sectional...
