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, 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 preset distance, the control unit informs the radiation source to emit the second X ray so as to scan the second part. |
