What are the differences between X-ray grids of different materials?

X-ray grid is a device used to control and adjust the energy spectrum and intensity of X-ray beams. It is made of different materials, including aluminum, copper, aluminum-rubidium alloy, etc. The differences between products made of different materials are mainly reflected in the following aspects:
Energy absorption characteristics: Aluminum grids mainly absorb low-energy soft X-rays and have less absorption of hard X-rays; while copper grids are more suitable for absorbing hard X-rays. Aluminum rubidium alloy not only absorbs low-energy X-rays, but also has good transmission performance for hard X-rays.
Transmission characteristics: Aluminum grids have better transmittance and are suitable for inspections that require higher X-ray intensity; copper grids have poor transmittance and are suitable for inspections that require lower X-ray intensity.
Energy spectrum adjustment: By using grids of different materials, the transmittance of photons in a specific energy range in the X-ray beam can be controlled, thereby making the energy spectrum of the X-ray beam more suitable for specific inspection needs.
Radiation dose: Lower material density allows more radiation to pass through, correspondingly increasing the risk of patient exposure to radiation.
In short, grids of different materials have differences in X-ray energy absorption characteristics, transmission characteristics, energy spectrum adjustment and radiation dose. The selection of appropriate grid materials can be based on different inspection requirements and safety considerations.
