Motion artifacts in medical ultrasound refer to unwanted distortions or blurring on an image caused by patient movement, transducer movement, or physiological motion (e.g., breathing, cardiac activity). These artifacts can significantly degrade image quality, obscuring anatomical details and potentially leading to misdiagnosis. Recognizing and minimizing motion artifacts is crucial for accurate interpretation and optimal diagnostic outcomes in ultrasound imaging.
Effective management of motion artifacts in ultrasound relies on proper patient instruction, breath-holding techniques, and optimized scanning protocols. Advanced ultrasound systems also employ image processing algorithms designed to compensate for minor movements, enhancing clarity and diagnostic confidence. Understanding the origins and appearances of motion artifacts is essential for sonographers and clinicians to ensure reliable and precise medical ultrasound examinations.
