Personnel screening system
First Claim
1. A scanning system, comprising:
- a first scanning side;
a second scanning side, wherein the first and second scanning sides, in combination, define an inspection area and wherein each of said first scanning side and second scanning side respectively comprises;
a first tower containing a first detection system configured to detect radiation scattered from the person;
a second tower containing a second detection system configured to detect radiation scattered from the person, wherein each of said first tower and second tower, respectively comprises;
a first housing defined by a first side, a second side and a third side that are connected to each other to form a triangular cross-section, wherein the first side has an exterior surface facing the person to receive radiation scattered from the person and an interior surface having a first substrate for receiving and converting said radiation into light, wherein the second side has an interior surface having a second substrate for receiving radiation after it passes through said first side and converting said radiation into light, and wherein the third side is defined by a surface supporting a plurality of photomultiplier tubes and a signal processing board placed proximate said plurality of photomultiplier tubes; and
a third tower containing an X-ray source assembly to generate a pencil beam, wherein the third tower has a front-end strip between an angled left side and an angled right side and wherein the front-end strip has an opening to allow the pencil beam to emanate therefrom for scanning the person, wherein the first tower and the second tower are detachably attached to the third tower so that the attachment abuts the first tower against the angled left side and abuts the second tower against the angled right side of the third tower and wherein said first tower and said second tower are attached on either side of the front-end strip.

Abstract
Further, the present specification is directed towards personnel screening systems comprising modular components, including detector and source units, where a dual axis scanning beam is employed. In one configuration, the subject under inspection remains stationary and is positioned between two scanning modules. The X-ray source assembly is designed to minimize the overall system footprint while still yielding the requisite field of view, low radiation exposure level, and required resolution. The modular components allow for a compact, light and yet sufficiently rugged overall structure that can be disassembled for ease of transportation and is also simple to reassemble at a required site for inspection.

17. A method of assembling a scanning system at an inspection site, the method comprising:
-
transporting at least one container to the inspection site, wherein said at least one container comprises; a first tower containing a first detection system configured to detect radiation scattered from a person; a second tower containing a second detection system configured to detect radiation scattered from the person, wherein each of said first and second towers comprise a first housing defined by a first side, a second side and a third side that are connected to each other in a polygonal cross-section, wherein the third side is defined by a surface supporting a plurality of photomultiplier tubes and a signal processing board placed proximate said plurality of photomultiplier tubes; a third tower containing an X-ray source assembly to generate a pencil beam, wherein the third tower has a front-end surface between an angled left side and an angled right side and wherein the front-end surface has an opening to allow the pencil beam to emanate therefrom for scanning the person; and a base; attaching said first tower, second tower, and third tower to the base; and attaching the first tower and the second tower to the third tower so that the first tower abuts the angled left side and the second tower abuts the angled right side of the third tower, wherein said first tower and said second tower are attached on either side of the front-end surface. - View Dependent Claims (18, 19, 20, 21, 22, 23)
