tissue results such as cataracts, skin reddening, and hair loss, which come about at reasonably higher amounts of radiation exposure and so are scarce for many types of imaging exams.

Previously mentioned equation shows us the SNR of the X-ray imaging technique obviously will depend on the article, represented by e−12∫μ(x)dx and also on the number of created photons for the supply N0. The SNR is proportional towards the square root of the quantity of emitted X-ray photons, as a result growing the amount of photons also improves the SNR.
