Final answer:
A common kVp setting used in CT is 100 kV.
Step-by-step explanation:
A common kVp setting used in CT is 100 kV.
The kVp (kilovolt peak) setting in CT (Computed Tomography) refers to the peak voltage applied to the x-ray tube. It determines the energy of the x-ray photons used in the imaging process. A higher kVp setting allows for greater penetration of x-rays, which is necessary to capture images of denser structures and tissues.
For example, when examining a broken leg in a cast, a higher kVp setting of 100 kV may be used to penetrate through the cast material and capture a clear image of the underlying bone.
