What is the primary purpose of using filters in fluoroscopy?

The primary purpose of using filters in fluoroscopy is to reduce patient exposure. Filters are designed to selectively absorb certain wavelengths of X-rays while allowing others to pass through. By reducing the low-energy scatter radiation that contributes to patient dose without significantly affecting the quality of the images, filters help minimize unnecessary radiation exposure to the patient during fluoroscopic procedures.

This is crucial in fluoroscopy, where procedures can be lengthy, leading to potentially higher radiation doses. By optimizing the beam quality and lowering the dose to the patient, filters play a key role in enhancing the overall safety of the procedure.

While enhancing brightness, improving contrast, and increasing resolution are important aspects of fluoroscopic imaging, these are not the primary reasons for utilizing filters. Instead, the focus on patient safety and exposure reduction is paramount in the design and application of filters in this context.
