A FACT-FINDING STUDY OF PEDIATRIC X-RAY EXAMINATIONS
Japanese Journal of Radiological Technology(1994)
摘要
In 1991, the inquiry was conducted among 114 institutes who belong to the society for pediatric radiological technology. The reply rate of the inquiry was 68.4%. The examinations included; chest, upper airway, abdomen, hip, skull, knee. The inquiry items consisted of irradiation conditions for; 6 month-olds, 3 year-olds, 7 year-olds, type of X-ray generator, model of automatic processor, FCR usage; for a total of 28 items in all. Single phase X-ray generator was almost never used. Most of the institutes used mid-high voltage as the irradiation condition for the chest examinations. The X-ray tube currents have peak to 200mA and 400mA. The irradiation times, the 50 ms full is the half above-mentioned. The automatic processor's developer temperatures were set lower than the recommented set point. The standard contrast films are used about 90%.
