Mechanisms of Bioeffects - Video Lesson

Hey, everyone. Welcome back to our course on patient care and safety in sonography. In this lesson, we will discuss mechanisms of bio effects, including thermal and mechanical effects, and their potential impact on biological tissues. Understanding these indices is crucial for minimizing patient exposure and ensuring the safe application of ultrasound imaging in clinical practice. Let's get started. Ultrasound imaging is widely regarded as a safe and noninvasive diagnostic tool. However, like any medical imaging modality, it carries some risks, particularly concerning bio effects. Bio effects in ultrasound result from sound waves interacting with biological tissues, primarily through thermal and mechanical mechanisms. Understanding these effects is essential for optimizing image quality while ensuring patient safety. First, let's discuss thermal bio effects. Thermal bio effects occur when ultrasound energy is absorbed by tissue and converted into heat.
