Videofluorography is the technique of obtaining radiographic images by photographing with a multiformat camera the television images produced during x-ray image intensified fluoroscopy. This technique of producing images has received considerable clinical use, but the radiation exposure used has been in doubt. Experiments were performed to evaluate this radiation exposure. It was found that the imaging chain was reducing mottle by temporal integration. These results were tested by comparing the image quality of videofluorographs with that of photofluorographs . The blurring effect of motion on images was also evaluated as this is a factor which must be balanced against the improvement of mottle due to temporal integration. It was found that exposures used for videofluorography were of the order of 10 microR (2.58 X 10(-9) C kg-1) to the input of the x-ray image intensifier.
视频荧光成像技术是指在X射线影像增强荧光透视过程中，使用多格式相机拍摄电视图像来获取射线照片影像的技术。这种成像技术在临床中已得到广泛应用，但所使用的辐射剂量一直存在疑问。为此进行了实验以评估这种辐射剂量。结果发现成像链通过时间积分减少了斑点。通过比较视频荧光成像仪和光荧光成像仪的图像质量对这些结果进行了验证。由于运动对图像的模糊影响也是一个必须与时间积分导致的斑点改善相权衡的因素，因此也对其进行了评估。结果发现，用于视频荧光成像的剂量在X射线影像增强器输入端约为10微伦琴（2.58×10⁻⁹库仑/千克）。
