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. WebAbstract Introduction: High kVp techniques, 15% or 10-kVp rules, are well-known dose reduction methods. Traditionally, the use of high tube potential (i.e. increased kVp) is … WebChanges in KVp is not equal throughout the ranges of KV (low med. high) A greater change is required at a higher KVp (greater than 90) compared with a lower KVP (less than 70) KVP affects density and other aspects - so, KVP is not primary factor for changes in density.example 50 kVp increase 10 kVp very dark greater change90 kVp increase 10 kVp dfb junior coach ausbildung
