Methods and apparatus for image reconstruction in distributed x-ray source CT systems |
摘要 |
A method for imaging an object that includes utilizing a computed tomography imaging apparatus having a distributed x-ray source to acquire samples of projection data of an object in angular and temporal space utilizing a predetermined sampling lattice. Acquired projection data is filtered utilizing a two-dimensional linear filter to produce filtered data, and the filtered data is then backprojected to obtain a reconstructed image of the object.
