Rad Source's Patented 4pi Technology

Rad Source 4pi technology (U.S. Patent 7346147 - X-ray tube with cylindrical anode) is actually a group of innovative technical developments that when taken together provide x-ray irradiation equipment capable of matching the capabilities of conventional self-contained gamma irradiators. To achieve this performance, Rad Source has developed a new type of x-ray emitter that increases the efficiency of x-ray irradiation. The emitter takes advantage of both forward and back emitted photons in a 4pi field so that all produced photons are utilized in the irradiation process. In addition, it uses a gold target to create a high Z spectrum with higher average energy than is currently available with any other x-ray device. In combination, the Rad Source 4pi emitter is over 2000% more efficient than conventional medical or industrial x-ray tubes.

The second part of our 4pi technology utilizes a unique combination of product movement and density optimization to take advantage of the large emitting area. Therefore our products can configure capacity and dose rate to best utilize our technology for the application. This insures optimum dose uniformity in the product you choose to irradiate. The capabilities and flexibility of 4pi technology results in an efficient, economical approach to manufacturing irradiators that allow for a large degree of latitude in configuration.

Dose rates can equal those of isotope self contained irradiators. By configuring multiple tubes, dose rates of 400 Gy per minute are possible.

U.S. Patent 7346147

Title:
X-ray tube with cylindrical anode

Document Type and Number:
U.S. Patent 7346147

Abstract:
A linear source of x-rays is disclosed wherein an elongated filament, mounted within a cylindrically formed anode, provides electrons around the filament, and along the length of said filament. The anode that comprises a high Z material such as gold, receives the electrons and emits X-rays in a 360 degree arc and along a substantial length of the anode. In one embodiment the tube is used for irradiation purposes.
