CAMRT Radiography Practice Exam

Does a technologist have control over the mA selection when using a falling load generator?

1. True

2. False

3. Only during peak load

4. Only in emergency settings

The correct answer is: True

The correct statement regarding a technologist's control over mA selection when using a falling load generator is that they do have some control over it. In a falling load generator system, the equipment is designed to automatically adjust the milliamperage (mA) during an exposure, starting from a maximum load and decreasing as the exposure progresses. This means that while the technologist can set the initial parameters for the exam, such as exposure time and the desired kilovoltage peak (kVp), the falling load generator will optimize the mA based on the selected exposure time to prevent overheating of the tube and ensure optimal image quality. It's important to note that control over mA is not absolute; the generator's system ultimately manages the adjustments. This feature is beneficial as it aids in maintaining consistency in imaging while reducing the risk of equipment damage. However, understanding that the technologist can influence the process initially through their settings is essential in this context.
