Portable computer tomography device

The device has a portable cabinet in which X-ray radiation source, X-ray radiation detector, object space between the source and the detector, high voltage generator and rotator and traversing control devices are arranged. A shield device (12) includes a shielded room arranged in the cabinet to shield the components of the device from produced X-ray radiation. The source, the detector and the object space are arranged in the shielded room. The high voltage generator, the rotator control device and the traversing control device are arranged outside the shielded room.
