Abstract
The present invention relates to a method and a system for producing X-ray images from an object. According to this invention, a shift-and-add method is used for generating a stack of linear tomography planes each associated with a different area inside the object. A set of shift values is defined from the consideration of ensuring that said stack of linear tomography planes fills in the tomographic volume with a spatial density adequate to the application. If so required by the application, some focal planes can be selectively processed for sharpness reduction in some areas to control the depth-of-field. A focus stacking method is used to synthesize a single 2D X-ray image from UPI the tomographic stack of images. A depth map of in-focus areas from the linear tomography stack can be used for creating a 3D object model.
