Intensity Essentials - Video Lesson

Welcome back to our discussion of the concept of intensity in ultrasound physics. A strong understanding of the role intensity plays in medical sonography is essential as it affects image quality, bio effects, and patient safety. This lesson explores ten essential truths about intensity and how changes in frequency, amplitude, and focus affect your ultrasound beam. Let's start with a reminder of the definition of intensity and how it is measured. Intensity is the concentration of power in a specific area of the ultrasound beam. It tells us how much energy is being delivered to the tissues. Intensity is typically measured in milliwatts per square centimeter and is determined by the equation intensity equals power divided by the total beam area. Think of it this way, as the power increases, the intensity increases and as the beam area increases, the intensity decreases. Now, let's dig into the ten basic
