Question

Quizplus · Accepted Answer

Heart penetration on an AP chest projection is achieved by adjusting the kVp settings, which allows for better visualization of structures within the chest, including those in the mediastinal region. Increasing the kVp results in a lower contrast image due to the higher energy photons being able to penetrate more dense tissues, such as the heart, but it does not decrease the amount of scatter radiation reaching the image receptor (IR).
