High kvp results in which of the following
Weba high kVp results in: a. less absorption and more transmission in atomic tissues b. less variation in the x-ray intensities exiting the patient c. increase interactions … Web12 de abr. de 2024 · Peak tube voltage (kVp): LDCT has been performed using tube voltages of less than or equal to 100 kVp [ 51 ]. Therefore, 80–100 kVp is commonly used in LDCT. Reducing the voltage from 120 kVp to 80 kVp increases the image noise and would require a four-fold increase in the tube current to maintain the image quality [ 52, 53, 54 ].

Choosing a high kVp creates films with a long-scale contrast of five steps – black, dark gray, medium gray, light gray, white. Optimum kVp for any body part
WebResults: The image resolution for a 1 mm multi-pinhole was between 0.88 and 1.38 mm. The detection limit for multi-pinhole operation was about 0.09 wt. %, while that for the single pinhole was about 0.13 wt. %. For a fixed number of pinholes, noise increased with decreasing number of photons.
