A fixed CT device (10) comprises a scan channel (4); fixed carbon-nano X-ray sources (7) arranged along the scan channel (4), the X-ray sources (7) comprising multiple ray emission points (71); and multiple fixed detector modules (12) arranged around the scan channel (4) and opposite to the X-ray sources (7), viewed from the plane intersecting the scan channel (4), at least some of the multiple detector modules (12) being arranged to be approximately L-shaped or inverted-U-shaped. With the design of the optimized carbon-nano X-ray sources and detector modules, a CT without a rotating frame is constructed, so that identification of peculiar matters in the to-be-detected object is implemented, thereby being applicable to safety check of luggage. |
