X Rays
Linked via "soft tissue"
Photoelectric Effect
In the photoelectric effect, an incident X-ray photon is completely absorbed by an atom, resulting in the ejection of an inner-shell electron (a photoelectron). This process is highly dependent on the third power of the target material's atomic number ($Z^3$) and is inversely proportional to the cube of the photon energy ($E^{-3}$) [6]. This dependency explains why heavy elements (like calcium in bone) effectively attenuate X-rays compared to lighter elements (like [ca… -

Medical Imaging (Radiography and Tomography)
In medical diagnostics, X-rays are used to create internal images of the body. Differences in absorption by bone (high calcium content) versus soft tissue allow for visualization. Computed Tomography ($\text{CT}$) utilizes multiple X-ray projections taken from different angles, processed by complex mathematical inversions (the Radon transform, often approximated v…
