Abstract

The present application is directed toward cargo scanning systems having scanners, each arranged to scan a respective object and generate a set of scan data, processors arranged to process each set of scan data to determine whether it meets a predetermined threat condition, workstations, and data management system arranged to direct data that meets the threat condition to one of the workstations for analysis.

First claim

The invention claimed is:

1. A vehicular traffic control and cargo scanning system for scanning a volume of vehicular traffic comprising:
a first X-ray scanning gantry having a first X-ray source and a first plurality of detector arrays, wherein said first X-ray scanning gantry is arranged over a first vehicle pathway and configured to form a first inspection region capable of receiving a first portion of said volume of vehicular traffic comprising at least a first vehicle with cargo and wherein said first X-ray scanning gantry is arranged to scan said first vehicle cargo and generate a first set of scan data;
a second X-ray scanning gantry having a second X-ray source and a second plurality of detector arrays, wherein said second X-ray scanning gantry is arranged over a second vehicle pathway and configured to form a second inspection region capable of receiving a second portion of said volume of vehicular traffic comprising at least a second vehicle with cargo and wherein said second X-ray scanning gantry is arranged to scan said second vehicle cargo and generate a second set of scan data, wherein at least one of the first and second X-ray scanning gantries is configured to scan subsequent vehicles in response to continuous traffic flow;
a storage array for receiving each set of first and second scan data directly from each of said first and second X-ray scanning gantries;
a computing device configured as a job dispatcher, threat detection processors arranged to process said first and second set of scan data from each of said first and second X-ray scanning gantries to determine whether said first and second set of scan data meets a predetermined threat condition, wherein said job dispatcher allocates processing time on one or more of the threat detection processors and wherein a sensitivity of at least one of the threat detection processors is adjustable based on said volume of vehicular traffic in the continuous traffic flow;
a plurality of workstations;
a memory for storing a plurality of operator profiles;
a data management means, wherein said data management means is arranged to direct data that meets the threat condition to one of the plurality of workstations for analysis and wherein said data management means directs said data to said one of the plurality of workstations based on at least one of said plurality of operator profiles; and
a vehicular traffic control system, comprising vehicular traffic lights and controlled by the job dispatcher, that directs a movement of said first and/or second vehicles into a holding bay in response to the first vehicle and/or second vehicle cargo meeting a threat condition or past the holding bay if the first vehicle and/or second vehicle cargo does not meet the threat condition, thereby enabling the scanning of the subsequent vehicles in the continuous traffic flow.

2. A system according to claim 1 , further comprising storage means arranged to store said first and second set of scan data from each of said first and second X-ray scanning gantries, wherein the data management means is arranged to control the storage means to control a supply of data to the threat detection processors.

3. A system according to claim 1 wherein the data management means is arranged to control a supply of said first and second set of scan data from each of said first and second X-ray scanning gantries to the workstations.

4. A system according to claim 1 wherein each workstation includes a user input to enable a user to provide an input allocating at least one of said first and second sets of scan data from each of said first and second X-ray scanning gantries to one of a plurality of threat categories.

5. A system according to claim 4 wherein the data management means is arranged to generate a control data set including a representation of a threat object and to monitor the threat category to which a user allocates at least one of the first and second sets of scan data from each of said first and second X-ray scanning gantries.

6. A system according to claim 5 wherein the data management means is arranged to generate the control data set by modifying at least one of the first and second sets of scan data from each of said first and second X-ray scanning gantries so as to include a representation of a threat object.

7. A system according to claim 1 further comprising a checking area wherein a movement control means is arranged to control movement of the first vehicle cargo or second vehicle cargo to the checking area if a user input allocates the first vehicle cargo or second vehicle cargo to a predetermined threat category.

8. A system according to claim 7 wherein the movement control means is arranged to control movement of the first vehicle cargo or second vehicle cargo so as to bypass the checking area if the user input does not allocate the first vehicle cargo or second vehicle cargo it to the predetermined threat category.

9. A system according to claim 8 wherein the data management means is arranged to monitor the threat categories allocated by a plurality of workstation users to modified data sets, and to generate a profile of the accuracy of each user's allocation.

10. A system according to claim 1 wherein the processing means is arranged to receive at least one set of secondary data associated with the object and to process the secondary data as well as the image data to determine whether the threat condition is met.

11. A system according to claim 10 wherein the secondary data comprises at least one of the following: weighbridge data, chemical detector data, gamma ray detector data and neutron sensor data.
