Abstract

The objective of this study is to verify whether X-ray can be visualized for imaging scattered radiation sources in X-ray radiography using a semiconductor radiation visualization camera with image processing and to evaluate its characteristics. Measurements were performed using a C-arm X-ray fluoroscopy device with a portable radiation visualization camera. The height of the radiation protective board and size of the irradiation field were the conditions that were varied during X-ray radiography. Based on the data obtained from the radiation visualization camera, output images were created displaying the intensity of the scattered radiation in color, which were then superimposed on the images captured with an optical camera. The scattered radiation generated by the phantom and within the X-ray tube were confirmed. These results indicate the feasibility of using this radiation visualization camera for imaging.
