Which technique is used to reduce radiation exposure in radiography?

Utilizing pulsed fluoroscopy is an effective technique for reducing radiation exposure in radiography. Pulsed fluoroscopy works by emitting x-ray radiation in short bursts or pulses rather than a continuous stream. This intermittent exposure reduces the total radiation dose to the patient while still capturing the essential images needed for diagnosis or treatment. By limiting the duration of exposure, pulsed fluoroscopy significantly minimizes the potential risk associated with prolonged radiation, making it a safer option for both patients and healthcare providers.

In contrast, using higher doses of radiation would inherently increase exposure rather than reduce it. Increasing Source-to-Image Distance can help reduce radiation dose due to the inverse square law but is not a direct technique like pulsed fluoroscopy. Shortening exposure time can also decrease exposure levels, but pulsed fluoroscopy is specifically designed for this purpose while maintaining image quality.
