Objects which cause attenuation of X-ray beam are shown as............in image
1. Radiolucent
2. Radiopaque
3. Gray
4. None of the above
Radiology
Answer: 2
Objects which cause attenuation of X-ray beam are shown as radiopaque in an
image.
Radiopaque materials absorb or block X-rays, leading to a reduced transmission
of the X-ray beam. This results in the appearance of white areas or shadows on
the X-ray image, indicating the presence of dense structures like bone, metal
restorations, or calculi. Radiolucent structures, on the other hand, allow
X-rays to pass through more freely, resulting in dark areas on the image.
