Method and apparatus for tomographic imaging and image reconstruction using recombinant transverse phase differentials

摘要

A method for imaging or reconstructing an image of an object includes the following steps: obtaining multiple original views of the object, each original view being obtained at a different relative orientation of the object from each other view; combining the multiple original views in an image plane to obtain a first composite image; phase inverting the first composite image to obtain a phase inverted composite image; combining the phase inverted composite image with each original view to obtain a second composite image; determining a differential between the second composite image and each original view to obtain a plurality of differentials; applying the plurality of differentials to the second composite image to obtain a resulting composite image; and optionally amplifying the resulting composite image to obtain a reconstructed image. Apparatus for carrying out the method may use analog circuitry, a high speed computer or a combination of analog and digital techniques may be used.
