Quick vehicle check system and method adopting multi-dose regional scanning
First Claim
1. A quick vehicle check system adopting multi-dose regional scanning comprising:
- a radiation source configured to produce a first X ray with a first dose and a second X ray with a second dose, wherein the first dose is smaller than the second dose, and the first X ray is used for checking a first part of a checked vehicle having a predetermined distance and the second X ray is used for checking a second part of the checked vehicle;
a first sensor configured to detect a set position of the checked vehicle;
a second sensor configured to detect a passing distance of the checked vehicle which is a distance traveled by the checked vehicle since the detection of the set position of the checked vehicle; and
a control unit coupled with the first sensor and the second sensor, configured to receive the set position of the checked vehicle from the first sensor and receive the passing distance of the checked vehicle from the second sensor, and when it is determined that the set position of the checked vehicle reaches a scanning region, the control unit informs the radiation source to emit the first X ray; and
when the passing distance of the checked vehicle reaches the predetermined distance, the control unit informs the radiation source to emit the second X ray so as to scan the second part wherein the set position of the checked vehicle is at a rear edge of a cab, front edge of a carriage or an arbitrary position therebetween.

Abstract
A quick vehicle check system comprises a radiation source which produces a first X ray with a first dose and a second X ray with a second dose, wherein the first dose is smaller than the second dose, and the first X ray is used for checking a first part of a checked vehicle and the second X ray is used for checking a second part of the checked vehicle; a first sensor for detecting a set position of the checked vehicle; a second sensor for detecting a passing distance of the checked vehicle; and a control unit coupled with the first sensor and the second sensor, which receives the set position of the checked vehicle from the first sensor and receives the passing distance of the checked vehicle from the second sensor.

7. A quick vehicle check method with multi-dose regional scanning comprising steps of:
-
emitting a first X ray of a first dose when it is detected that a set position of a checked vehicle reaches a scanning region; scanning a second part of the checked vehicle with a second X-ray of a second dose when the checked vehicle has passed a predetermined distance since the detection of the set position of the checked vehicle and scanning of a first part of the checked vehicle is completed, wherein the first dose is smaller than the second dose; and stopping X-ray scanning when the second part of the checked vehicle has passed through the scanning region, wherein the set position of the checked vehicle is at a rear edge of a cab, front edge of a carriage or an arbitrary position therebetween. - View Dependent Claims (8, 9, 10, 11, 12)
