Topic explanation

Standard explanation

X-ray imaging forms an image from differences in the amount of X-ray radiation transmitted through and absorbed by different tissues.

Key points

• I = I₀e⁽−μx)
• Bone: X-rays entering the body do not all reach the detector. Different tissues attenuate X-rays by diffe
• Soft Tissue: Many soft tissues produce less attenuation than bone, though attenuation varies with composition and
• Different tissues attenuate X-rays differently.
