Abstract: An imaging method, accesses cone beam computed tomography (CBCT) data and displays, on a display monitor, at least one view of the CBCT data. The method provides an interface for a user to indicate a tomosynthesis reconstruction plane on the displayed view of the CBCT data; and displays a tomosynthesis image on the display monitor according to the indicated tomosynthesis reconstruction plane.

Abstract: An imaging method, accesses a set of low-energy projection images and performs a low-energy reconstruction using the low-energy projection images. A synthesized intermediate low-energy projection image is generated. A high-energy reconstruction is performed using a set of high-energy projection images. A synthesized intermediate high-energy projection image is generated. A dual-energy reconstruction is performed using at least one low-energy projection image, the synthesized intermediate low-energy projection image, at least one high-energy projection image, and the synthesized intermediate high-energy projection image.

Abstract: A method for geometric calibration of a radiography apparatus disposes at least one radio-opaque marker in the field of view of the radiography apparatus. A series of tomosynthesis projection images of patient anatomy is acquired from the detector with the x-ray source at different positions along a scan path. For at least three projection images showing the position of the radio-opaque marker, the spatial and angular geometry of the x-ray source and detector are calculated according to the positions of the marker. A tomosynthesis image is reconstructed according to the calculated geometry. A rendering of the reconstructed image is displayed.

Abstract: A method for tomosynthesis volume reconstruction acquires at least a prior projection image of the subject at a first angle and a subsequent projection image of the subject at a second angle. A synthetic image corresponding to an intermediate angle between the first and second angle is generated by a repeated process of relating an area of the synthetic image to a prior patch on the prior projection image and to a subsequent patch on the subsequent projection image according to a bidirectional spatial similarity metric, wherein the prior patch and subsequent patch have n×m pixels; and combining image data from the prior patch and the subsequent patch to form a portion of the synthetic image. The generated synthetic image is displayed, stored, processed, or transmitted.
