The photon energy spectra, energy fluence, photon fluence, exposure and mean energy of the diagnostic x-ray tube for comparing 4 Kinds of basic rectifier waveform, is constant potential, 12 puls, 6puls and 2puls, have been computed by based Kramer's theory and Hettinger's experimental date modified for filtration and voltage waveform. Also, the quantam and energy conversion efficency from a electron to a x-ray photon in x-ray tube are computed for given various tube voltage and waveform. Form those results, it becomes clear that relation between characteristics of primary radiation and tube operating conditions. The exposure and transminssion of radiation in aluminum are good agreement with experimental values obtained under a variety of tube voltage.
