Abstract: Provided is a method and apparatus for providing a three-dimensional (3D) image. A plurality of first projection images may be created by detecting X-rays which are emitted toward an object at different angles. A plurality of second projection images with respect to a partial volume of the object may be created by applying a forward projection and interpolation to at least one of the plurality of first projection images. A left image and a right image may be selected from among the plurality of second projection images, and the selected left image and right image may be displayed for a user as a 3D projection image.

Abstract: An X-ray imaging method and apparatus are provided for forming an X-ray image having reduced noise and showing a clear boundary of a lesion region. The X-ray imaging method includes performing a first main shot which irradiates an object in a compressed state by using X-rays at least once to obtain a single two-dimensional image, performing a second main shot which irradiates the object by using X-rays at different positions to obtain a plurality of two-dimensional images, and forming a two-dimensional final image by removing a lesion region having a unclear boundary from each of the plurality of two-dimensional images and substituting a lesion region of the single two-dimensional image into an area which corresponds to the removed lesion region.
