- 摘要：
PROBLEM TO BE SOLVED: To reduce a memory capacity of temperature-dependent dark current correction data widely while correcting the dark current corresponding to a characteristic change of a X-ray detector.
SOLUTION: A X-ray image diagnostic system involves temperature correction coefficient memory means 17 for memorizing the temperature correction coefficient showing a proportional relationship of the X-ray detector and the dark current, and dark current data renewal means 11 updates the dark current data added with a detecting temperature of the temperature detector 3 and memorizes to the dark current data memory means 16, and image generating means 13 computes the difference between the detecting temperature and the detecting means added to the updated dark current data, and computes the temperature-dependent dark current correction data based on the temperature correction coefficient (14), and the dark current correction data memorized in the dark current data memory means 16 is corrected by using the computed temperature-dependent dark current correction data, and a transparent X-ray data output from the X-ray detector 2 is corrected, so that a X-ray projected image of a subject 100 is generated.
