Embodiments of methods andor apparatus for 3-D volume image reconstruction of a subject, executed at least in part on a computer for use with a digital radiographic apparatus, can obtain image data for 2-D projection images over a range of scan angles. The CCDs provide a single-channel mosaiced image output. A tuned conductor element among the conductor elements has a first end at a distance from the antenna element which is lower than \u03bb10, and has a length Hwire adapted to generate an electromagnetic resonance in the tuned conductor element corresponding to the wavelength \u03bb. The query system also includes a materialized view associated with a portion of the set of data, and a MVQR component to translate each of a range predicate of the materialized view and a range predicate of a query into a canonical range representation format in materialized view metadata and query metadata, respectively, to enable the query to search the materialized view. The detachable cylinder is optionally secured to the pan by coupling the fasteners to the subset of perforations and by rotating the detachable cylinder in a first direction to move the fasteners into a locked position.
