Question

To maintain an adequate number of x-ray photons for an adult abdominal fluoroscopy, which of the following manual exposure setting is most appropriate?

1. 1-5 mA
2. 2-3 mA
3. 1-2 mA
4. 3-5 mA

Answer 1

The most appropriate manual exposure setting for an adult abdominal fluoroscopy to maintain adequate x-ray photons is 3-5 mA, which ensures diagnostic image quality while considering patient exposure.

Step-by-step explanation:

To maintain an adequate number of x-ray photons for an adult abdominal fluoroscopy, the most appropriate manual exposure setting would typically be in the higher range of milliamps per second (mA) to ensure sufficient penetration and image quality. Given the options provided, the best choice would be 3-5 mA.

This range is more suitable for producing a clear and diagnostic-quality image of the abdomen, as it ensures that a sufficient number of x-ray photons reach the detector through this relatively dense and absorptive area of the body. It's essential in fluoroscopy to balance the need for adequate image quality with the goal of minimizing radiation exposure to the patient.
