Which instrument is used to verify the mA and kVp accuracy of an x-ray machine?

The instrument used to verify the mA (milliampere) and kVp (kilovolt peak) accuracy of an x-ray machine is an equipment survey device. This type of device is specifically designed to assess the performance parameters of x-ray equipment, ensuring that the machine operates within the specified standards for both mA and kVp settings.

Checking mA accuracy is important because it influences the quantity of radiation produced during an x-ray exposure, which ultimately affects image quality and patient safety. Similarly, kVp affects the penetration power of the x-rays, influencing contrast and diagnostic effectiveness. An equipment survey device typically includes specialized tools and features that allow technicians to perform accurate and comprehensive evaluations of these critical parameters.

Understanding the function of the equipment survey device is key in maintaining regulatory compliance and ensuring the safety and efficacy of x-ray diagnostic procedures.
