PROBLEM TO BE SOLVED: To enable a detector having a comet to be also employed in medical technology by correcting a comet artifact. SOLUTION: An image system (6) contains a comet artifact correcting means having evaluation devices (24 and 25), a target value estimating means (26) and detail estimating means (27 and 28) are connected to the evaluation devices (24 and 25), these estimating means determine a target value and a detail value from an electric signal outputted from an X-ray detector at a disturbance place, the output signals of the estimating means (26 to 28) are supplied to a correcting stage (29), and the correcting stage forms a signal. |
