Question

An increase in kilovoltage will serve to
produce a longer scale of contrast

Answer 1

Increasing the kilovoltage in X-ray imaging results in a longer scale of contrast.

Step-by-step explanation:

Increasing the kilovoltage (kV) in X-ray imaging will result in producing a longer scale of contrast.

When electrons are accelerated through a higher voltage, they gain more kinetic energy. This increased energy allows them to generate X-ray photons with higher energies. X-ray photons with higher energies have better penetrating abilities and can produce images with greater contrast.

For example, if an X-ray machine operates at 50.0 kV, the X-ray photons produced will have a maximum energy of 50 keV. In contrast, if the machine operates at 100 kV, it can generate up to 100-keV X-ray photons. The higher energy X-ray photons can penetrate denser materials and produce darker shadows in the X-ray image.
