First Claim
1. A volumetric stationary CT system comprising:
- at least one stationary detector extending generally around at least a portion of an imaging volume; and
at least one stationary distributed X-ray source placed proximal to the at least one stationary detector, wherein the at least one stationary detector and the at least one stationary distributed X-ray source are configured to cooperate to contribute towards completeness in acquired data for image reconstruction.

Abstract
Configurations for stationary imaging systems are provided. The configurations may include combinations of various types of distributed sources of X-ray radiation, which generally include addressable emitter elements which may be triggered for emission in desired sequences and combinations. The sources may be ring-like, partial ring-like, or line-like (typically along a Z-axis), and so forth. Combinations of these are envisaged. Corresponding detectors may also be full ring detectors or partial ring detectors associated with the sources to provide sufficient coverage of imaging volumes and to provide the desired mathematical completeness of the collected data.
