摘要： A CT apparatus without a gantry is disclosed. The CT apparatus comprises a scanning passage; a stationary X-ray source arranged around the scanning passage and comprising a plurality of ray emission focal spots; and a plurality of stationary detector modules arranged around the scanning passage and disposed opposite the X-ray source. In embodiment, at least some of the plurality of detector modules are arranged substantially in an L shape, a semicircular shape, a U shape, an arc shape, a parabolic shape, or a curve shape when viewed in a plane intersecting the scanning passage. The present invention ensures that the stationary gantry type CT system has a small size, and a high data identification accuracy.

摘要： A stationary CT apparatus and a method of controlling the same are disclosed. The stationary CT apparatus comprises: a scanning passage; a stationary carbon nanotube X-ray source arranged around the scanning passage and comprising a plurality of ray emission focal spots; and a plurality of stationary detector modules arranged around the scanning passage and disposed opposite the X-ray source. In addition, at least some of the plurality of detector modules are arranged in a substantially L shape or a substantially Π shape when viewed in a plane intersecting the scanning passage. Reconstruction of the CT apparatus without a rotary gantry is achieved and special substances in an object under inspection is identified by optimizing design of the carbon nanotube X-ray source and the detector device. The present invention ensures that the stationary gantry type CT system has a small size and a high accuracy. The present invention is particularly suitable for safety inspection of baggage.
