Speckle artifact in medical ultrasound refers to the grainy, salt-and-pepper appearance on an image, resulting from the constructive and destructive interference of scattered sound waves. This inherent imaging artifact, while degrading image quality, is distinct from true anatomical structures. Understanding speckle is crucial for accurate diagnostic interpretation, as it can obscure subtle pathologies or mimic genuine findings.
Optimizing ultrasound images involves minimizing speckle artifact, enhancing diagnostic clarity. Techniques like speckle reduction algorithms and compound imaging are employed to improve signal-to-noise ratio and provide clearer visualization of tissues and organs. Mastering speckle recognition is key for sonographers to differentiate true anatomical details from imaging noise, thereby improving diagnostic confidence in various medical applications.
