How does the collimator affect scatter radiation?

A collimator reduces scatter radiation by limiting the x-ray beam to a specific area, which helps focus the radiation on the target while minimizing exposure to surrounding tissues. By narrowing the beam, it decreases the amount of radiation that can scatter in unintended directions, thus improving image quality and reducing patient dose. Additionally, collimators help to enhance contrast in imaging by decreasing the background noise caused by scattered photons. Overall, effective collimation is essential for optimizing radiographic procedures.
