How much does the use of intensifying screens reduce the radiation dose to the patient during examinations?

The use of intensifying screens in radiographic examinations significantly enhances the efficiency of the imaging process by converting x-ray photons into visible light, which then exposes the film. This conversion allows for a much lower dose of radiation to be applied to achieve the desired image quality.

Specifically, intensifying screens can reduce the radiation dose to the patient by as much as 95%. This remarkable reduction occurs because the screens increase the film’s sensitivity; thus, less x-ray exposure is needed to obtain a diagnostic image. It not only protects the patient from unnecessary radiation but also improves the overall safety of radiographic procedures. The incredible degree of dose reduction attributable to the use of these screens underscores their importance in modern radiological practices.
