Claim 16:
17. A system to generate a combined image from a plurality of image data, comprising:
a processor system configured to execute instruction to:
access a first image data acquired at a first imager position of an imager;
access a final image data acquired at a final imager position of the imager;
determine at least a portion of a feature having stored predetermined dimensions included in both the first image data and the final image data;
determine an alignment transformation to align pixels or voxels of the feature between the first image data and the final image data without tracking a position of the imager;
determine an alignment transformation based on the alignment transformation to align the first image data and the final image data based on the determined alignment transformation, wherein the alignment transformation is operable to correct for misalignment of the first image data and the final image data in at least one degree of freedom of movement of the image between the first imager position and the final imager position that is outside a Z-axis movement of the imager without tracking a position of the imager; and
output the alignment transformation.
