Both collimators and optimal kV are used to control the production of scattered radiation.
Collimators are devices used to restrict the size and shape of the X-ray beam. By narrowing the X-ray beam, collimators help reduce the production of scattered radiation. This improves the image quality and reduces unnecessary radiation exposure to surrounding tissues.
The choice of optimal kilovoltage (kV) is crucial in X-ray imaging. Selecting an appropriate kV helps control the energy of the X-ray beam. Higher kV settings are more effective in penetrating tissues, reducing the likelihood of scattered radiation. Adjusting the kV based on the imaging task and the patient's anatomy contributes to effective scatter radiation management.
Therefore, both collimators and optimal kV settings play essential roles in minimizing scattered radiation during radiographic procedures.
