A cone-beam scanning system scans along a half circle. The reconstruction uses a weighting function which decreases for rows farther from the scan plane to take the redundancy of the projection data into account. Another embodiment uses a circle plus sparse helical scan geometry. Image data can be taken in real time.

A method for 3-D volume image reconstruction of a subject. 2-D projection images are obtained over a range of scan angles, and one or more truncated images are identified from the obtained images. From each of the one or more truncated images, a corrected truncated image is formed by a repeated process of identifying a row of image data values in the one or more truncated images, assigning an extension length to one or both ends of the row according to the row location in the truncated image, and extending the truncated image data for the row of image data values by applying a row-dependent cosine function to each value in the extension length. A 3-D volume image is reconstructed using one or more of the corrected truncated images.

A method for obtaining a 3-D image. An initial volume image is obtained of a subject wherein the subject is stationary and in a first pose. One or more 2-D images of the subject are obtained as the subject is moving between the first pose and a second pose. An endpoint volume image of the subject with the subject stationary and in the second pose is obtained. At least the initial volume image is modified according to the one or more obtained 2-D images to form at least one intermediate volume image that is representative of the subject's position between the first and second pose. The at least one intermediate volume image can be displayed.

A method for 3-D volume image reconstruction of a subject, executed at least in part on a computer, obtains image data for 2-D projection images over a range of scan angles. For each of the plurality of projection images, a noise-corrected projection image is generated by steps of transforming the image data according to a variance-stabilizing transform to provide transformed image data, applying Gaussian based noise suppression to the transformed image data, and inverting the transformation of the noise-suppressed transformed image data to generate the noise-corrected projection image. The noise-corrected projection image is stored in a computer-accessible memory.

Embodiments of methods and/or apparatus for 3-D volume image reconstruction of a subject, executed at least in part on a computer for use with a digital radiographic apparatus can obtain a 3D volume reconstruction or projection image by generating a first-filtered set of projection images from a plurality of 2-D projection images taken over a range of scan angles and a different second-filtered set of projection images from the plurality of 2-D projection images. Then, for example, a first 3-D volume image of the subject from the first-filtered set of projection images and a second 3-D volume image of the subject from the second-filtered set of projection images can be combined using different weighting combinations in at least two corresponding portions to generate the 3-D volume image of the subject.

Embodiments of methods and/or apparatus for 3-D volume image reconstruction of a subject, executed at least in part on a computer for use with a digital radiographic apparatus, can obtain image data for 2-D projection images over a range of scan angles. For each of the plurality of projection images, an enhanced projection image can be generated. In one embodiment, a first scatter intensity distribution through the plurality of projection images can be modulated based on a first scaling function and a SPR to generate a second scatter intensity distribution through the plurality of projection images, which can be combined with the original plurality of projection images.
