In recent years, multi-phase rectifying instruments have come to be widely used in tune with the popular use of continuous angiography and TV fluoroscopy techniques. However, the quality as well as quantity of X-rays emitted by the 6-pulse or 12-pulse rectifying instrument has not been fully elucidated as compared with that by the conventional, singlephase 2-pulse rectifying method. The following report is an attempt to such an analysis.(1) In experiment, no great qualitative difference was observed between the X-rays generated by the 2-pulse unit and those by the 12-pulse one, but in quantity the 12-pulse unit was capable of producing approximately 1.5 times as much X-rays as by the 2-pu1se unit.(2) In theory, by expounding Kulenkampff's experimental formula, comparison was made of the X-ray outputs obtained by different rectifying methods. Practically no qualitative difference was observed between the x-rays from the 6-pulse unit and those from the 12-pulse or constant potential unit, while a slight difference was seen between the X-rays from the 2-pulse unit and those from the 12-pulse or constant potential unit. With an inherent filter of 3mmAl, the quantity of X-rays from the 12-pulse or constant potential unit was 1.4-1.5 times of those from the 2-pulse one, while the X-rays from the 6-pulse one was 1.3-1.4 times in quantity of the 12-pulse one.(3) Our measurements show a good agreement with the absorption curve reported by the Radiation physics Laboratory in N. B. S., whereas Kulenkampff's calculations present only a slight attenuation, which proves a qualitative hardness of the X-rays produced.
