PROBLEM TO BE SOLVED: To correct the output signal of defective pixels from each semiconductor element of a flat plane detecting part in a radiographic apparatus more accurately. SOLUTION: The X-ray diagnostic apparatus has a flat plane detecting part for detecting transmitted X-rays through a subject by using plural semiconductor elements and converting the X-rays to electric signals, a signal read-out part for reading out the converted detected signals, a defect processing part 4 for inputting the read-out image signals and correcting the output signals of defective pixels by each semiconductor element of the flat plane detecting part, and an image display part for displaying the corrected image signals. The defect processing part 4 has means 12 and 13 for correcting the output signals of defective pixels of the flat plane detecting part by detecting irregularity of the input/output characteristics of the adjacent pixels Therefore, the defect of the displayed image can be stably corrected without being affected by the irregularity of the input/output characteristics of each pixel used for the correction. |
