초록

In an attempt to provide optimum kVp for four spot films of stomach examinations, we measured experimentally film density and scatter radiation with field size. And to investigate the effect of concentrations in barium sulphite and kVp in spot films of stomach fluoroscopy were carried out and the following results were obained. 1. The entire density of film by field size has the sharpest increase from $10cm^2$ to $100cm^2$, and relatively flattened curve beyond $500cm^2$ in field size. 2. The quantity of scatter radiation reaching an X-ray film depends upon field size: the larger the fields, the more scatter radiation. 3. It is necessary for increasing 3 to 5kVp as for the absence of barium sulphite and 5 to 7 kVp in the case of 20 per cent and 25 per cent in barium sulphite concentrations to produce uniform density in the four spot films for stomach fluoroscopy.
