| 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. |
