Question

30 multiple choice 1 point when comparing two x - ray beams, one at 60 kvp and another at 85 kvp. adding aluminum to the 60 kvp beam greatly reduces the skin dose to the patient the 85 kvp beam will offer a lower entrance skin exposure adding 0.5 mm of aluminum to the 85 kvp beam will require no additional mas in order to maintain beam intensity all of the above. 31 multiple choice 1 point the build - up of tungsten deposits on the inside of an aged x - ray tube adds to the added filtration inherent filtration radiation output mr mas

Explanation:

Step1: Analyze X - ray beam properties

Higher kVp (85 kVp compared to 60 kVp) results in more penetrating x - ray beams. Adding aluminum to a lower kVp (60 kVp) beam filters out low - energy photons, reducing skin dose. A higher kVp beam is more penetrating and offers lower entrance skin exposure. Also, adding a small amount of aluminum (0.5 mm) to a high kVp (85 kVp) beam may not require additional mAs to maintain beam intensity.

Step2: Analyze tungsten deposits in X - ray tube

Tungsten deposits on the inside of an aged x - ray tube contribute to inherent filtration as they act as an additional material that the x - ray photons must pass through before leaving the tube.

Answer:

1. D. all of the above
2. B. inherent filtration
