- Purpose : a research on reducing exposure dose of the operator was progressed by removing unnecessary X-ray and scattering rays being spread in radial shape by use of subsidiary accessory of C-arm. Material and method : Mobile type image amplification system (C-arm), doughnut-shaped aluminium with thickness of 2T of which inside is filled with powder type Barium and glass dosimeter, Phantom were used and by placing phantom on operation table, C-arm center in over tube condition was positioned on abdomen of phantom. At ringer stand being distanced from the center by 50cm, glass dosimeter was positioned at 160cm that is average eyeball location of adult male, 140cm that is location of thyroid and 50cm that is location of gonad, respectively and result value was analyzed by performing a test for 5 times in the same way as above while irradiating, measuring 90kVp, 5mAs for 1 minute in the order of non-used accessory, doughnut-shaped aluminium with thickness of 2T that circled tube to be matched with its size, doughnut-shaped aluminium of which inside is filled with Barium. Result : Non-used accessory was measured as 0.032mGy at eyeball position, 0.041mGy at thyroid position and 0.091mGy at gonad position, respectively. When covering Al, 0.027mGy at eyeball position, 0.031mGy at thyroid position and 0.083mGy at gonad position were measured respectively and this result showed that in eyeball, 15%, thyroid 20% and 8% in gonad were reduced. When filled Al cover inside with barium, 0.025mGy, 0.030mGy and 0.081mGy were measured in eyeball, thyroid and gonad respectively and it showed that in eyeball, 21%, thyroid 25% and 10% in gonad were reduced. Conclusion : By use of proper accessory, exposure dose of the operator could be reduced. In addition, consistent concern for reducing exposure dose shall be required through adequate distance, shortening of using time.
