An imaging technique is provided for acquiring scatter free images of an object. The technique includes acquiring a plurality of projection images of the object using a source and a detector oriented at a plurality of projection angles relative to the object, and generating a plurality of scatter free projection images by correcting the plurality of projection images based on respective ones of a plurality of stored scatter images. The scatter images are generated and stored for each of the projection angles by positioning a scatter rejection plate between the object and the detector. The technique further includes reconstructing a three-dimensional image of the object based on the scatter free projection images.

A Digital Radiograph (DR) acquisition system for generating a scatter-corrected X-ray image is provided. The DR acquisition system includes a digital detector configured to produce a two-dimensional (2D) X-ray image of an object of interest. The digital detector is configured to detect X-rays emitted from an X-ray source and transmit the X-rays through the object of interest and generate the 2D X-ray image in response to the detected X-rays. The DR acquisition system further includes an image processor coupled to the digital detector, and a display unit. The image processor is configured to generate projection image data from the 2D X-ray image and iteratively reconstruct the 2D X-ray image to generate a scatter-corrected X-ray image based on the generated projection image data. The display unit configured to display the scatter-corrected X-ray image in conjunction with the 2D X-ray image.

A digital radiography imaging system for acquiring digital images of an object, and a method for transforming digital images into an absolute thickness map characterizing the object under inspection. The system includes a radiation source for directing radiation through a desired region of the object, and a radiation detector having a plurality of sensing elements for detecting radiation passing through the object. Numerical data generated from each sensing element is calibrated, for example by correcting for variations in radiation paths between the source and detector, by correcting for variations in the spatial frequency response (MTF) of the detector, by correcting for variations in the geometric profile of the object under inspection, and by correcting for material contained in and/or around the object. The calibrated data is processed in order to generate and display an absolute thickness map of the object. The calibration procedures are adapted for extracting a thickness map from both isotope sources and X-ray tube sources.
