Which color shows denser materials in X-Ray imaging?

1. Red

2. Blue

3. Green

4. Orange

The correct answer is: Blue

In X-ray imaging, denser materials are typically represented by a specific palette of colors on the imaging software that interprets the X-ray data. Among the color options provided, the color blue is often used to indicate denser materials because it contrasts effectively against the softer tissue colors, which usually lean towards lighter shades. This visual differentiation helps radiologists and technicians quickly identify areas of interest that warrant closer examination, such as bones or foreign objects, that absorb more radiation and appear denser in the images. While other colors can indicate varying densities, blue is a common standard in the representation of denser materials within medical imaging contexts, making it the most appropriate choice in this case.
