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.
本研究的目的是验证使用具有图像处理功能的半导体辐射可视化相机,在X射线摄影中能否对散射辐射源进行X射线成像可视化,并评估其特性。使用配备便携式辐射可视化相机的C型臂X射线透视设备进行测量。在X射线摄影过程中,改变的条件是辐射防护板的高度和照射野的大小。根据从辐射可视化相机获得的数据,创建以颜色显示散射辐射强度的输出图像,然后将其叠加在用光学相机拍摄的图像上。确认了由体模产生的以及X射线管内的散射辐射。这些结果表明使用这种辐射可视化相机进行成像的可行性。
