What is the purpose of a cumulative manual-reset timer in fluoroscopy?

The purpose of a cumulative manual-reset timer in fluoroscopy is primarily to inform the fluoroscopist of the exposure time. This device accumulates the total time that the x-ray beam is active during the procedure and displays this information clearly. By providing a visual indicator of the cumulative radiation exposure time, the fluoroscopist can make informed decisions about the use of fluoroscopy and take steps to minimize exposure to both the patient and themselves.

This timer is crucial in maintaining radiation safety as it allows the operator to be aware of how long they have been exposing the patient to radiation. The ability to monitor this exposure time helps ensure that the procedure is conducted in a manner that limits unnecessary radiation and follows established safety protocols. Having this information readily available is essential in practices that require strict adherence to guidelines regarding radiation exposure.
