Abstract: Disclosed is an apparatus for generating X-ray data including a processor that receives first image data indicating that a hidden item is hidden in a non-hidden item, and second image data indicating the non-hidden item, and generates output data and a buffer. The processor includes an extraction unit that extracts first hidden data corresponding to the hidden item from the first image data, a shape change unit that generates second hidden data by performing a shape change on the first hidden data, an interpolation unit that generates third image data by performing interpolation based on the second image data and the second hidden data, and a projection unit that generates the output data by projecting the third image data onto a 2D plane. The buffer stores a plurality of parameters associated with generation of the first hidden data, the second hidden data, the third image data, and the output data.
