1. A computer-implemented method for self-determination of shot geometry for use in open-configuration portable x-ray computed tomography (CT), the method comprising:
inputting, from a portable or movable x-ray generator and detector, one or more x-ray shot images into a computing system, wherein the placement of the portable or movable x-ray generator and detector is not mechanically repeatable;
determining, by the computing system, one or more shot geometries with respect to a coordinate system, the coordinate system is defined by constellation of markers, the constellation of markers are identified from the one or more inputted x-ray shot images, the one or more inputted x-ray shot images are from the portable or movable x-ray generator and detector;
reconstructing, by the computing system, a volume image from the one or more inputted x-ray shot images and the one or more shot geometries; and
outputting, by the computing system, a reconstructed volume image.
