<P>PROBLEM TO BE SOLVED: To acquire a sufficient radiograph without artifact by avoiding the influence of leak charges from a radiation detector. <P>SOLUTION: For a radiographic signal acquired from an object region, the signal obtained by subtracting a GateOff signal when a transistor switch of each detecting element of the radiation detector is turned off from a GateOn signal when a transistor switch is turned on is set as a leak-corrected radiographic signal, and it is acquired from an omission region as a predetermined threshold of a pixel saturation value. For a radiographic signal of the threshold or higher, the GateOn signal is set as the radiographic signal. Thus, sufficient radiographic images without artifact are created both in the object region and omission region. <P>COPYRIGHT: (C)2009,JPO&INPIT |
