PROBLEM TO BE SOLVED: To provide a fluoroscopic device which provides images of high quality by clearly indicating to an operator the position and size of an area for detection by a brightness detector which detects the brightness of an optical image conversion means which converts transmitted X-rays into optical images, and optimizing X-ray conditions in the clearly indicated area for detection. SOLUTION: The position and range of a part of interest, as detected by a brightness detector 18 detecting the brightness of an optical image conversion means 4 which converts transmitted X-rays into optical images, are stored in a part-of-interest display data memory 20 as part-of-interest display data, and when the data needs to be displayed on a part-of-interest display data memory 13, the data are superimposed on display image data by a superimposing means 22. When the display of the part-of-interest display data is not required, a part-of-interest switch 21 is used for control so that the data are not superimposed on the display image data. Thus, since the area of interest in the image displayed on a monitor 13 can be known, X-ray conditions in the area can be optimized and images of high quality can be obtained. |
