ABSTRACT:
An x-ray source provides both a line focus output and a point focus output, and is mounted on a rotatable support to allow easy changing between the two. A housing has ports at different angular positions relative to an anode, and each port has an associated optic appropriate for an x-ray beam passing through that port. Three or four ports may also be used to allow for different types of beam conditioning. The different beam optics may also do conditioning based on wavelength, and the anode may be of a composite material to provide different wavelength ranges. The rotatable support may be manual or motorized, and a lockout mechanism may be used to ensure that only one port is active at a time. The support may also be located on a movable table that is movable in multiple perpendicular directions.
