Enhancement, Mirror Image, Speed Error - Video Lesson

Hey everybody. Welcome to today's lesson on artifacts in ultrasound imaging. This lesson focuses on three common artifacts, enhancement, mirror image, and propagation error artifacts. Understanding these phenomena is essential for accurate image interpretation and differentiation of real structures from imaging artifacts. Let's get started. Remember, ultrasound artifacts are image distortions that occur due to the interaction of ultrasound waves with tissue structures. While some artifacts can hinder accurate interpretation, others provide valuable diagnostic clues. First, let's take a look at enhancement artifacts. Enhancement occurs when ultrasound waves pass through a structure with lower attenuation than the surrounding tissues. Since attenuation is the gradual loss of sound energy due to absorption, reflection, and scattering, tissues with lower attenuation allow more sound energy to reach deep.
