What is a common artifact associated with digital imaging?

• A. Banding effect
• B. Moiré pattern
• C. Pixelation
• D. Overexposure

Answer: (B)

The Moiré pattern is a common artifact associated with digital imaging, particularly when using digital radiography systems. This phenomenon occurs when two grids or repetitive patterns overlap in a way that creates an undesirable visual effect. In medical imaging, for instance, if a digital imaging detector is used in conjunction with a grid pattern that is not aligned properly, the resulting image can display these wavy, interference-like lines known as a Moiré pattern. This can compromise the diagnostic quality of the image, making it challenging to interpret certain features. Understanding the Moiré pattern is essential for radiologic technologists because it emphasizes the importance of proper alignment and calibration of imaging equipment. By being mindful of these factors, technologists can mitigate the risk of this artifact and produce clearer, more accurate images for clinical evaluation.
