THE INVENTION
The disclosed invention relates generally to tomosynthesis, and more
particularly, to a method and apparatus for performing a reconstruction
algorithm (Specification 1).
Independent claim 1 is illustrative:
1. A method for reconstructing a three-dimensional dataset
representative of an imaged object, said method comprising:
acquiring views of an object from at least two projection
angles with an imaging system including at least one radiation
source and at least one detector array to generate a projection
dataset of the object;
backprojecting the views across an imaged volume to
generate backprojected data; and
processing the backprojected data using a non-linear
operator to generate a three-dimensional dataset consisting of a
plurality of images representative of the imaged object.
