摘要

CT fluoroscopy provides pseudo real-time cross sectional imaging and has been used in our clinic for biopsies,rndrainage and pain control. In the fluoroscopic configuration the radiologist stands in the room adjacent to therntable as in conventional angiography. Because of concerns regarding patient doses, measurements were made tornestimate doses.rnEffective doses were calculated using the method of Huda and the data of NRPB. It was found that as far as thernpatient is concerned, two minutes of CT Fluoroscopy gave a similar effective dose as a standard abdomen CTrnexam. As in other CT scanners, the scattered dose decreases rapidly away from the radiation plane and is 1 mGyrnper minute at 10 from the image plane.
