Provided is a fluoroscopy system that can detect an affected area with improved accuracy and that allows the user to easily determine a position suitable for biopsy. The invention employs a fluoroscopy system 1 including a light source device 17 that emits white light and excitation light for irradiation of a subject A a white-light-image generating section 29 that generates a white-light image by capturing the white light reflected from the subject A a fluorescence-image generating section 30 that generates a fluorescence image by capturing fluorescence emitted from the subject A irradiated with the excitation light an intensity-distribution generating section 31 that generates a fluorescence intensity distribution of pixels of the fluorescence image a peak-detecting section 32 that detects a fluorescence-intensity peak in the fluorescence intensity distribution a peak-count comparing section 33 that calculates a count of the peak an image-combining section 35 that generates a combined image by superimposing a display representing a region including a pixel having the fluorescence intensity at the peak on the white-light image or the fluorescence image based on the peak count and a monitor 43 that displays the combined image thus generated.
