What is the purpose of the cumulative timer in fluoroscopy?

The cumulative timer in fluoroscopy is designed to serve as a reminder of total exposure time. In fluoroscopy, prolonged exposure to ionizing radiation can lead to increased risk of exposure to the patient and the operator. The cumulative timer keeps track of the total fluoroscopy time during a procedure, providing important information that can alert the operator when exposure has reached a predetermined limit. This feature is essential for patient safety, as it helps ensure that the fluoroscopic examination is conducted efficiently while minimizing unnecessary radiation exposure.

By maintaining awareness of the cumulative time, operators can make informed decisions about whether to continue the fluoroscopic examination or to consider alternatives, thus enhancing safety protocols during imaging procedures.
