Rectification Constant - A value of the heat unit formula that varies depending on the generator used. Generators used in Radiography - single phase generator delivers pulsating x-ray beam (1), Three phase generator = 3 phase 6 pulse machine (1.35) , High frequency generator = 3 phase 12 pulse machine (1.41) Rectification - The rectifier of the x-ray tube changes alternating current (AC) to direct current (DC). This process ensures that the x-ray production flows in the right direction; fr...
