Patent Images
1. A method of processing data for medical imaging, the method comprising:
- providing a set of first modality data including a plurality of views from a first imaging modality;
providing a set of second modality data from a second imaging modality;
generating a motion estimate from each of the plurality of views in the set of first modality data by registering the set of first modality data with the set of second modality data;
generating a motion corrected model of the set of first modality data by forwarding projecting the set of first modality data including the motion estimate; and
wherein neither the first nor the second image modality comprises Magnetic Induction Tomography.

Abstract
A set of first modality data is provided to an intra-reconstruction motion correction method. The set of first modality data includes a plurality of views. A set of second modality data is provided to the method. A motion estimate is generated for each of the plurality of views in the set of first modality data by registering the set of first modality data with the set of second modality data. A motion corrected model of the set of first modality data is generated by a forward projection including the motion estimate.
