title: [Report based on fiscal 2010 diagnostic X-ray equipment questionnaire survey (conditions of radiography)].
abstract: This is the eighth investigation which has been carried out every 5 years since 1974 for the purpose of grasping the trend of X-ray devices and the radiographic condition. We gathered it up mainly on a radiographic condition, in this report. As for the chest radiography and double contrast gastrography, introduction of the flat panel detector (FPD) advanced in comparison with the last survey. Ratio of the imaging system at chest radiography was 65% for computed radiography (CR), 33% for FPD, 1% for screen/film (S/F), and 1% for others. The radiographic condition of FPD was current time product less than CR. Ratio of the imaging system at gastrography was 3% for CR, 48% for FPD, 34% for image intensifier-digital radiography (I.I.-DR), and 15% for S/F. The tube voltage and the exposure time were similar to the last survey time, but the tube current became lower. Through this survey, the change of the radiographic condition was seen in the radiography part where introduction of the FPD advanced. We think the continuous survey is necessary in future.
