Abstract
A multi-channel static CT device is provided, and the multi-channel static CT device includes: a scanning channel including a plurality of scanning sub-channels; a distributed X-ray source including a plurality of ray emission points arranged around the scanning channel; and a detector module including a plurality of detectors arranged around the scanning channel, wherein the plurality of detectors are arranged corresponding to the plurality of ray emission points.
Claims16
A multi-channel static CT device, comprising:
- a scanning channel comprising a plurality of scanning sub-channels, wherein each scanning sub-channel of the plurality of scanning sub-channels comprises a conveying mechanism configured to convey an inspected object;
- a distributed X-ray source comprising a plurality of ray emission points arranged around the scanning channel;
- and
- a detector module comprising a plurality of detectors arranged around the scanning channel, wherein the plurality of detectors are arranged corresponding to the plurality of ray emission points,
- wherein a part of the plurality of ray emission points corresponding to one of the plurality of scanning sub-channels is operable independently of another part of the plurality of ray emission points corresponding to another one of the plurality of scanning sub-channels, so as to implement a multi-channel detection mode,
- wherein the multi-channel detection mode comprises a first detection sub-mode, wherein in the first detection sub-mode, at least two scanning sub-channels among the plurality of scanning sub-channels operate, each of the at least two scanning sub-channels is configured to carry a respective inspected object placed on the each of the at least two scanning sub-channels, and the at least two scanning sub-channels in operation are individually controlled,
- wherein the multi-channel detection mode further comprises a second detection sub-mode, wherein in the second detection sub-mode, at least two adjacent scanning sub-channels among the plurality of scanning sub-channels operate, the at least two adjacent scanning sub-channels are configured to carry an inspected object placed on the at least two adjacent scanning sub-channels, the conveying mechanisms in the at least two adjacent scanning sub-channels in operation are uniformly controlled to operate in a same direction and at a same speed, and parts of the plurality of ray emission points corresponding to the at least two adjacent scanning sub-channels operate.
