METHOD AND SYSTEM FOR ITERATIVE RECONSTRUCTION
First Claim
1. ) A method for reconstructing an image of an object, the image comprising a plurality of image elements, the method comprising:
- accessing image data associated with the plurality of image elements;
applying a first algorithm to the plurality of image elements;
selecting a spatially non-homogenous set of the plurality of image elements; and
applying an iterative algorithm to the set of image elements to reduce an amount of time necessary for reconstructing the image, or to improve an image quality at a fixed computation time, or both.

Abstract
A method for reconstructing an image of an object, the image comprising a plurality of image elements, is disclosed. The method includes accessing image data associated with the plurality of image elements, applying a first algorithm to the plurality of image elements, selecting a spatially non-homogenous set of the plurality of image elements, and applying an iterative algorithm to the set of image elements to reduce an amount of time necessary for reconstructing the image, or to improve an image quality at a fixed computation time, or both.

14. ) An imaging system comprising:
-
a controller; a source in signal communication with the controller, the source generating imaging energy in response to a control signal from the controller; a detector array configured to receive the imaging energy and make available image data in response thereto; a translating table configured for receiving an object thereon and operable to translate in relation to the source and the detector array; and an image reconstructor electrically coupled to the detector array and the controller, the image reconstructor responsive to the controller and receptive of the image data to reconstruct an image comprising a plurality of image elements via a technique comprising the application of a first algorithm to the plurality of image elements, selection of a spatially non-homogenous set of the plurality of image elements, and application of an iterative algorithm to the set of image elements to reduce an amount of time necessary for reconstructing the image. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
