Scatter radiation is effectively reduced by using collimators. Collimators work by restricting the size and shape of the x-ray beam before it reaches the patient, which minimizes the amount of tissue exposed to the radiation. This reduction in exposed tissue decreases the amount of scatter radiation produced because there is less primary beam interaction with the body.

When the primary x-ray beam is collimated, it results in less scatter, leading to a clearer image and reduced radiation dose to both the patient and the healthcare personnel present. This technique is crucial in improving image quality and safety in radiographic procedures.

Other methods, such as changing film speed or using lead aprons, may improve image quality or help protect personnel, but they do not directly address the primary source of scatter radiation in the same effective manner as collimators do. X-ray tube filtration helps to remove low-energy photons that do not contribute to image formation but again does not play as direct a role in reducing scatter as collimation does.
