Question

Quizplus · Accepted Answer

The anode heel affect is a variation in photon intensity across the exposure field and occurs because the heel of the anode absorbs more photons than the toe. It should be considered when the structure of interest is more than 43 inches long. The anode heel affect is not best used with the thinner body toward the cathode, so option 4 is incorrect. Therefore, the correct answer is option B, which includes statements 2 and 3 only.
