What is the primary purpose of using pulsed fluoroscopy during procedures?

• A. To reduce radiation exposure
• B. To increase frame rate
• C. To improve image sharpness
• D. To shorten setup time

Answer: (A)

Pulsed fluoroscopy is used primarily to cut down radiation dose by turning the X-ray beam on only briefly in each cycle instead of continuously. This lowers the average dose because the beam is on for a fraction of the time (the duty cycle), while still providing enough real-time imaging to guide the procedure. Clinicians can choose a pulse rate that balances image quality with dose, so you get sufficient visual information without baking in unnecessary exposure. While this mode may change the frame cadence and can affect perceived smoothness, its main goal is to reduce exposure. It does not inherently improve image sharpness, nor does it shorten setup time.
