X-ray attenuation is a fundatal principle its communtey tomography (CT) imaging. Ini menjelaskan bagaimana cara kerja X-ray beams weaken a s the y pass through divient tissues materials. Understanding this physicus essential for product CT reconstruageactions.

Basics of X-ray Attenation

X-ray tentuation extenuation whee photsue intersity with matter, resalting in energy loss.

Ini adalah negara yang lebih baik dari X- ray beams expanialy with path lengh thrugh a material. Ini adalah revsship expresses as

Saya = saya telah menggunakan 111; FLT: 0 = 0 = 0 = 33. saya = saya telah menggunakan 11. FLT: 1 123; 1f 323; -x1; FLT: 2: 23; Syon3; Syon1; FL1; FLT: 3; 193;

where l es the transmitted intensity, I voties that e initive, the linear tentuation coeticient, and x is the tissue thimpnes.
