Lobe Artifact - Video Lesson

Hey everybody, welcome back to our lesson on ultrasound artifacts. Today we'll be discussing lobe artifacts. These artifacts arise from energy emitted outside the main ultrasound beam, and can lead to misplaced echoes, making it crucial to understand their formation, differentiation, and mitigation strategies. By identifying and minimizing these artifacts, sonographers can improve diagnostic accuracy and ensure ensure more reliable imaging. Let's get started. First, let's define lobe artifacts. Lobe artifacts are unintended echoes caused by ultrasound energy emitted outside the main beam, leading to misplaced structures on an image. Blurred edges or false echoes make it difficult to differentiate objects close to one another on an image. Lobe artifacts degrade lateral resolution. These artifacts can obscure or mimic anatomical features impacting diagnostic accuracy.
