What are the advantages to using a high kilovoltage peak (kVp)? Choose all that apply.
  1. Shorter exposure time
  2. High-contrast images
  3. Increased detail
  4. None of the above
Explanation
Answers: A and C - The advantages to using a high kilovoltage peak (kVp) are shorter exposure time and increased detail.
When the electrons in the x-ray tube are sped up by increasing the kilovoltage, the x-rays are more powerful. A high kVp requires less exposure time and produces images with low contrast which reveal great detail in areas such as existing bone levels.
