During a prolonged fluoroscopic procedure, how can the technologist minimize the patient's radiation dose while maintaining image quality?

Minimizing a patient's radiation dose during a prolonged fluoroscopic procedure while maintaining image quality is a critical task for technologists. Choosing to decrease the pulsed fluoroscopy frame rate is effective because it reduces the amount of radiation the patient is exposed to over time. When the frame rate is reduced, fewer images are captured per second, which results in less continuous radiation being emitted during the procedure.

In fluoroscopy, radiation exposure is linked to the frequency of images taken; thus, lowering the frame rate allows for better control over the dose while still providing sufficient imaging quality for diagnostic purposes. This approach helps to strike a balance between minimizing radiation exposure and ensuring that image quality remains adequate for the procedure.

In contrast, increasing the source-to-skin distance can also reduce radiation dose but may not be feasible in some situations due to technical limitations or the need for specific positioning. Using continuous fluoroscopy mode typically results in higher radiation exposure as the beam is constantly on, which is contrary to the goal of dose reduction. Finally, avoiding the use of grids does not have a direct impact on patient dose and may compromise image quality, as grids are utilized to improve contrast by reducing scatter radiation. Therefore, the option to decrease the pulsed fluoroscopy frame rate is the most
