What is the maximum exposure rate allowed by the FDA for high dose fluoroscopic mode in roentgen per minute (R/min)?

The FDA has established a maximum exposure rate for high dose fluoroscopic mode at 20 roentgens per minute (R/min). This limit is set to ensure patient safety while using fluoroscopic imaging, which involves higher radiation doses due to its prolonged use and the need for real-time imaging. Keeping the maximum exposure at 20 R/min helps mitigate potential health risks associated with excessive radiation exposure, such as skin damage or increased cancer risk.

It's important to note that exceeding this exposure rate could lead to unnecessary radiation dose to patients, which is unacceptable in medical practice. Therefore, maintaining the exposure within this regulated limit is crucial for the safe and effective use of fluoroscopic procedures.
