1. A portable X-ray imaging system, comprising:
- a housing defining a tunnel for receiving an article to be inspected;
a conveyor for conveying the article through the tunnel at a pre-defined speed;
an X-ray production system positioned within said housing, comprising;
a first X-ray source pulsed at a first time to generate a first electron beam along a first longitudinal axis, wherein said first X-ray source is positioned above the conveyor;
a second X-ray source pulsed at a second time to generate a second electron beam along a second longitudinal axis, wherein the first and second X-ray sources are positioned opposing to each other, wherein the second time is different than the first time, and wherein said second X-ray source is positioned above the conveyor;
a target positioned between the first and second X-ray sources, wherein the target has a first side facing the first X-ray source and a second side facing the second X-ray source, wherein the first electron beam strikes the first side at a first impact point to generate a first X-ray cone beam and the second electron beam strikes the second side at a second impact point to generate a second X-ray cone beam, and wherein respective apexes of the first and second X-ray cone beams are separated by a distance; and
an X-ray detector system positioned within said housing and comprising at least one two-dimensional flat panel detector for generating a first image of the article corresponding to the first X-ray cone beam and a second image of the article corresponding to the second X-ray cone beam, wherein the first and second sides of the target are inclined at an angle with respect to a top surface plane of said at least one detector and wherein the pre-defined speed of the conveyor is a function of at least the first time and the second time.

Abstract
The present specification discloses systems for a compact and portable X-ray transmission imaging system that is used for security inspection of small items. The system includes a housing with an X-ray tunnel for receiving an article to be inspected, a conveyor for conveying the article through the tunnel, a dual source X-ray system, with a central target, for generating two overlapping cone beams, and a two-dimensional X-ray detector system for detecting the generated dual energy X-rays.
