DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray CT inspection vehicle,
In particular, by making the industrial X-ray CT system on-board,
The present invention relates to a novel X-ray CT inspection vehicle that can be moved to an arbitrary location to perform CT inspection of cargo.

[0002]

2. Description of the Related Art In recent years, firearms, drugs,
In many cases, cannabis and the like are hidden together, and inspection of these cargoes at airports, ports, and the like has become important. In particular, in the case of narcotics, they may be mixed with other powdered products, making it difficult to distinguish them.

Conventionally, there are various methods for performing these inspections (a method relying on a human can, a metal detection method, or an X method).
Inspection vehicles using the X-ray transmission imaging system, in particular, the X-ray transmission imaging system are widely used for inspection of cargo interiors because of their mobility and simplicity.

[0004]

However, this X
The inspection vehicle using the line transmission imaging method is a transmission imaging method, so its application range is limited, and there are the following problems.

[0005] (1) Since the X-ray energy is small (120 to 150 kV), the size of the inspection cargo is limited to small and low-density materials, and there is no penetrating power even if it is used for high-density materials. Therefore, photography is not possible.

(2) Even when a container of a thick metal plate is filled with a low-density material, it is difficult to identify the presence or absence of the low-density material because X-rays are affected by the metal material.

(3) It is similarly difficult to identify a cargo composed of color or type of high and low density materials.

As a result, in the inspection of the X-ray transmission imaging system,
Insufficient information is available to make a reasonable judgment on the contents of the cargo. In particular, recently, the need for detailed identification of cargo contents in crisis management has been rapidly increasing, and thus the effectiveness of (1), (2), and (3) above has been demonstrated. An application of an X-ray tomography method (X-ray CT) is considered. However, at present, there is no dedicated X-ray CT inspection apparatus for cargo, and moreover, a freely movable on-board X-ray CT inspection apparatus has a large size. I don't think of a typical concept. If you look at the spread of conventional X-ray radiography inspection vehicles for cargo,
The need for a T inspection car is more than the former. SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and its object is to be able to freely move anywhere and to accurately image and display the state (relative density distribution, structure) inside a cargo. X
An object of the present invention is to provide a line CT inspection vehicle .

[0009]
