RADIOGRAPHIC APPARATUS AND RADIOGRAPHIC SYSTEM

PROBLEM TO BE SOLVED: To provide a radiographic apparatus capable of accurately removing an offset portion caused by a lag from image data in the continuous radiography or in the long-length radiography.SOLUTION: A controller 22 of the radiographic apparatus 1 previously prepares an expression representing the relations between reference image data dh in processing the image data d and the dose I of irradiated radiation, and estimates the dose I of the irradiated radiation based on the expression and the reference image data dh extracted from the respective image data d read from respective radiation detection elements 7 in the previous radiography. The controller estimates the offset portion Olag superimposed on the respective image data d read in the following radiography, caused by the lag generated in the previous radiography, and computes true image data d* for each radiation detecting element by subtracting the estimated offset portion Olag caused by the lag from the image data d read in the following radiography.
