What is the purpose of using filters in radiography?

Using filters in radiography serves the important purpose of removing low-energy X-rays, which do not contribute to the quality of the images being captured. These low-energy X-rays can lead to increased patient radiation dose without enhancing the diagnostic quality of the image. By filtering them out, radiologists can improve the overall image quality while minimizing the patient's exposure to unnecessary radiation.

This process helps in producing clearer images by ensuring that only the more penetrating (and therefore more useful) X-rays reach the detector or film. Consequently, this contributes to better diagnostic outcomes, as critical details can be more distinctly viewed in the resulting images.
