摘要：
A radiography apparatus includes a radiation source, a radiation detector, and processing circuitry. The processing circuitry is configured to obtain an X-ray image of an object, obtain a focal spot size of a radiation source used to generate the obtained X-ray image, and estimate a magnification of the obtained X-ray image. The processing circuitry is also configured to obtain, using a look-up table and the obtained focal spot size, a deconvolution kernel. The processing circuitry is also configured to generate a corrected X-ray image by performing a deconvolution operation on the obtained X-ray image using the obtained deconvolution kernel and the estimated magnification.
