A wedge filter is classified as what type of filter?

A wedge filter is classified as a compensating filter because its primary purpose is to modify the radiation intensity across the treatment field to ensure that the dose distribution is more uniform. In radiation therapy, certain areas of the tumor may require higher doses, while other areas need less. The wedge shape of the filter allows for selective attenuation of the radiation beam. Thicker portions of the wedge filter attenuate more radiation, thereby compensating for the differences in tissue density or depth that could lead to underdosing or overdosing in specific areas of interest.

Compensating filters, like wedge filters, are designed to improve dose uniformity and enhance treatment effectiveness. They are particularly useful in treatments that involve irregularly shaped tumors or anatomical variations, allowing medical dosimetrists to customize treatment plans to better meet the needs of individual patients.
