WebMethods: An experimental design was used to study the effect of varying kilovoltage peak (kVp) and milliampere-seconds (mAs) on a male phantom pelvis when using a direct digital radiography (DR) flat panel detector. The radiation intensity was varied by increasing the kVp and reducing mAs. WebHigh peak kilovoltage (kVp) (e.g., 120–130 kVp) ... The high kVp technique is also used to reduce obscuring effects of the ribs on underlying pulmonary pathology.
