What is the typical range of kVp settings used in CT imaging?

In computed tomography (CT) imaging, the typical range of kilovolt peak (kVp) settings is 80 to 150 kVp. This range is chosen to optimize image quality while ensuring adequate penetration for various tissue densities encountered in diagnostics. The kVp setting directly influences the X-ray beam's energy, affecting both the contrast and the dose to the patient.

Lower kVp settings, such as those in the 50 to 80 kVp range, may produce images with insufficient penetration for denser tissues, thus compromising image quality. Conversely, higher kVp settings, exceeding 150 kVp, might not be necessary for most routine CT scans and could lead to increased radiation exposure without significant benefits in image quality. Therefore, the 80 to 150 kVp range is widely accepted as providing a good balance between diagnostic quality and patient safety.
