Abstract: A photon beam dose enhancement is controlled by configuring at least two magnets in a staggered opposing coil configuration, such that the first central field vector of the first magnet is more anti-parallel than parallel to the second central field vector of the second magnet. In one form, the first central field vector of the first magnet is rotated between ±90° to 180° to the second central field vector of the second magnet. Typically, the first central field vector is noncoaxial with the second central field vector. The resulting magnetic field configuration has a larger portion of higher magnitude magnetic field that can reach deeper into a target body and provides additional space within the region of higher magnitude that can accommodate larger portions of a body.

Abstract: An x-ray source that can produce high-brilliance x-rays at a low cost and from a small footprint includes a radiofrequency (RF) photoinjector, an accelerator module (such as a linear superconducting accelerator moducle), a high-power optical laser apparatus, and a passive enhancement cavity. A stream of photons generated by the laser apparatus is accumulated in the enhancement cavity, and an electron stream from the photoinjector are then directed through the enhancement cavity to collide with the photons and generate high-brilliance x-rays via inverse-Compton scattering.

Abstract: Portable x-ray devices and methods for using such devices are described. The devices have an x-ray tube powered by an integrated power system. The x-ray tube is shielded with a low-density insulating material containing a high-Z substance. The devices can also have an integrated display component. With these components, the size and weight of the x-ray devices can be reduced and the portability of the devices enhanced. The x-ray devices also have an x-ray detecting means that is not structurally attached to the device and therefore is free standing. Consequently, the x-ray devices can also be used as a digital x-ray camera. The portable x-ray devices are especially useful for applications where portability is an important feature such as in field work, remote operations, and mobile operations such as nursing homes, home healthcare, or teaching classrooms. This portability feature can be particularly useful in multi-suite medical and dental offices where a single x-ray device can be used as a digital x-ray camera in multiple offices instead of requiring a separate device in every office.

Abstract: Methods for connecting electrical potential to an extractor cup at the cathode of a miniature x-ray tube are disclosed. The various connection schemes are designed to form a rugged and conveniently manufacturable connection between the metal extractor cup and one side of the cathode filament, so that the extractor cup shapes the path of electrons as desired en route to the anode of the tube. Some of the disclosed connections involve evaporation of conductive metal or other materials off the filament when the filament is first activated. Others involve applying a paste or paint conductive precursor directly to a base to connect a post and the extractor, the paste being heat-cured after the completion of assembly. Others involve a fine wire or spring strip from one filament post to the walls of the extractor cup. Other schemes include welded or brazed wires or foil, crimping, pinching, swaging and other connections, all made inside the tube enclosure.
