X-ray backscatter mobile inspection van
First Claim
1. An inspection system for inspecting an object, the system comprising:
- a. an enclosed conveyance characterized by an enclosing body;
b. a source of penetrating radiation contained entirely within the body of the enclosed conveyance for generating penetrating radiation;
c. a spatial modulator for forming the penetrating radiation into a beam for irradiating the object with a time-variable scanning profile;
d. a detector module contained entirely within the body of the enclosed conveyance, for generating a scatter signal based on penetrating radiation scattered by contents of the object;
e. a proximity sensor for generating a relative motion signal based on a relative disposition of the enclosed conveyance and the inspected object; and
f. a controller for forming the signal into an image of the contents of the object based in part on the scatter signal and the relative motion signal.

Abstract
An inspection system based upon an enclosed conveyance such as a van capable of road travel. The conveyance is characterized by an enclosing body, or skin. The system has a source of penetrating radiation contained entirely within the body of the enclosed conveyance and a spatial modulator for forming the penetrating radiation into a beam for irradiating an object with a time-variable scanning profile. A detector module generates a scatter signal based on penetrating radiation scattered by contents of the object, while a proximity sensor generates a relative motion signal based on a relative disposition of the conveyance and the inspected object. An image is formed of the contents of the object based in part on the scatter signal and the relative motion signal. A detector, which may be separate or part of the scatter detector module, exhibits sensitivity to decay products of radioactive material.

12. A method for inspecting an object with penetrating radiation, the method comprising:
-
a. generating a beam of penetrating radiation originating entirely within the body of an enclosed conveyance;
b. scanning the penetrating radiation across the object with a time-variable scanning profile;
c. detecting penetrating radiation scattered by the object into the body of the enclosed conveyance and generating a scatter signal;
d. generating a relative motion signal based on a relative disposition of the enclosed conveyance and the inspected object; and
e. forming an image of the contents of the object based in part on the scatter signal and the relative motion signal.
