Question

If the radiographer wants to increase kVp so they can reduce pt exposure, which technique would be used?

1. increase kVp by 15%, decrease mAs 25%
2. increase kVp by 15%, decrease mAs 50%
3. increase kVp by 15%, decrease mAs 75%
4. increase kVp by 15%, decrease mAs 100%

Answer 1

The radiographer can increase kVp and decrease mAs to reduce patient exposure in radiography.

Step-by-step explanation:

To reduce patient exposure in radiography, the radiographer can increase the kVp (kilovoltage peak) while decreasing the mAs (milliamperage-seconds). This technique involves increasing the energy of the X-ray beam, which allows it to penetrate the patient's body more efficiently, reducing the amount of radiation needed.

Option 1: Increase kVp by 15%, decrease mAs by 25%

Option 2: Increase kVp by 15%, decrease mAs by 50%

Option 3: Increase kVp by 15%, decrease mAs by 75%

Option 4: Increase kVp by 15%, decrease mAs by 100%

In this scenario, Option 2 would be the most suitable because it reduces the mAs by 50%, resulting in a significant decrease in patient exposure while still maintaining image quality.
