X-ray filter

An X-ray filter is a device placed in the path of X-ray beams to shape their characteristics before they reach the patient or detector. Its main purpose is to selectively absorb or reduce lower-energy X-rays, which are less useful for imaging and can increase unnecessary radiation exposure. By filtering out these softer X-rays, the filter improves image quality and ensures safer, more effective imaging. Filters are made from materials like aluminum or copper and are designed to optimize the balance between image clarity and patient safety.
