When looking at a X-ray, the white is known as the ____ and the dark is known as the ____

A	opacities/lunacies
B	lunacies/opacities
C	air/bone
D	None of the above

Explanation:

Detailed explanation-1: -Dense materials, such as bone and metal, show up as white on X-rays. The air in your lungs shows up as black. Fat and muscle appear as shades of gray.

Detailed explanation-2: -If you find some dark black spots, there is a possibility that there is excess gas in that area, and the white spots will signify the abnormal growth. The bones in the x-ray identify themselves as the while areas, and the air is black.

Detailed explanation-3: -The amount of darkness in the radiographic image reflects the radiographic density. It is called “transmitted density” in conventional film radiography because it measures the light transmitted through the film. In digital imaging, it refers to the shift of the histogram to the lower grey levels.
