Abstract
A method and apparatus are provided which utilize a circular tomosynthesis system to collect 2-D x-ray projection radiograph data of an object being evaluated. The collected data is then transformed into a form suitable for cone beam volumetric computed tomography (cone beam VCT) reconstruction. Once the data has been transformed, a cone beam VCT reconstruction algorithm may be utilized to reconstruct a 3-D image of the object.
