Which of the following is recommended for increasing radiographic contrast while maintaining radiographic density?
a. Increase kVp and increase exposure time.
b. Decrease kVp and decrease exposure time.
c. Increase kVp and decrease exposure time.
d. Decrease kVp and increase exposure time.
d. Decreasing kVp produces longer wavelength x-rays, which results in a high-contrast radiographic image. Because decreasing kVp also decreases the quantity of
x-rays produced, the density may be maintained when decreasing kVp by increasing exposure time.
