CAMRT Radiography Practice Exam

What is one of the safety features of fluoroscopy equipment?

1. Max 10 mA

2. At least 40 cm between focal spot and tabletop

3. Max 100 mGy/min tabletop exposure

4. Minimum 5-minute exposure timer

The correct answer is: Max 100 mGy/min tabletop exposure

The safety feature of fluoroscopy equipment that relates to the maximum allowable tabletop exposure is particularly important for minimizing the radiation dose to patients and personnel during procedures. Keeping the tabletop exposure to a maximum of 100 mGy/min ensures that radiation levels are monitored and controlled, reducing the risk of overexposure during extended periods of fluoroscopic imaging. Monitoring the dose rate helps to maintain safety protocols and allows the operator to take appropriate action if exposure levels approach this limit, thereby enhancing patient safety and promoting responsible radiation use in medical imaging. While other options may also represent important specifications for fluoroscopy equipment, the maximum tabletop exposure is directly aimed at radiation protection, which is a central concern in medical imaging. The other features, while relevant, do not directly correlate to the immediate control of radiation exposure as effectively as the maximum dose rate does.
