The invention discloses a driving device used for a human body security check system, which comprises a driving mechanism (100) that is used for driving a radiation source (10), a collimator (12) and a detector (14) to move along the preset direction, wherein the radiation source (10), the collimator (12) and the detector (14) are fixedly connected together, so that an integral structure can be formed. In addition, the invention also discloses the human body security check system comprising the driving device. In the system and the device, a mode of an integral arm such as a C-shaped arm or an E-shaped arm is adopted for connecting and fixing the radiation source, the collimator and the detector in a scanning imaging device and cause the radiation source, the collimator and the detector to make synchronous lifting motion, so that the influence of inertia force on synchronization accuracy is guaranteed to be within an acceptable range, and no scanning fringe exists in scanned images; meanwhile, the system is simple in structure and high in reliability. |
