What is X-Ray Beam Filtration and Collimation about?

Filters are used to shape the X-ray beam by removing low-energy photons. Different types of filters include inherent filtration from the tube housing, added filtration like aluminum and copper filters, and compound filters. Filtration increases with kVp. Filters reduce patient dose and exposure factors by hardening the beam. X-ray beam restrictors like cones, cylinders and collimators are used to regulate the size and shape of the X-ray beam. Collimators provide the best field sizes and alignment of the l
