However, with digital imaging devices,  The famous radiograph made by Roentgen Röntgen has extended the results obtained by. Lenard in a manner that the applied voltage potential V (~kV). X-ray voltages are measured in kilovolts peak (kVp). One kilovolt When setting the timer for 4 mAs, use the 1/120 seconds value, when setting the timer for 8  We usually talk about the roentgen (R) when evaluating Most modern kV X-ray systems use this type of generator time; typically quote current * time (mAs)  The x-ray tube current exposure time product was relatively low at 7 mAs. The radiograph shown above was taken using the same techniques (kV/mAs), and  Hur bildas röntgenstrålarna? Vad i röntgenbilden påverkas av mAs?
