5 wrz 2024 · Energy transfer paths: According to the different luminescence mechanisms of the X-ray sensitizers and emission centers, energy transfer can be divided into singlet-singlet and triplet-triplet energy transfer.
5 wrz 2024 · In this review, we summarize recent progress in fabricating high-performance energy transfer-based scintillators using a variety of X-ray sensitizers and emission centers and provide a detailed interpretation of the corresponding energy transfer mechanisms and their tremendous impact on the operation of X-ray imaging scintillators.
3 sie 2018 · X-rays belong to the group of electromagnetic rays, hence, they follow the rules of electromagnetic radiation. Electromagnetic radiation transports energy, also called radiant energy, through space by waves and photons, just as radio waves, the visible light or microwaves.
17 lut 2021 · X-rays are electromagnetic radiation emitted by electrons outside the nucleus of atoms. They typically have energies in the range of 100 eV to 500 keV, corresponding to a wavelength range from 2.5 Pm to 10 nm (Als-Nielsen and McMorrow 2011).
X-rays that pass through, or are transmitted through, the body deposit energy onto the image receptor. This leaves areas of greater exposure (black areas) on the image that represent areas of lower attenuation in the patient’s body. X-rays that are scattered inside the patient’s body, change direction but may still reach the image receptor.

Describe the interactions in the anode and the x-ray energies they produce. Explain these properties of x-rays: divergent rays, photon energy, visibility, speed, ability to produce scatter, effect on phosphors, effect on photodetectors, and the ability to cause biological damage.
