A portable X-ray system includes an X-ray scanner coupled to a module for processing and visualization of digital signals; and foldable intake and output trays configured to pass an object in and out of the scanner module. The foldable intake and output trays are articulated approximately in their middle. A first drum extends substantially across an entire opening of the scanner tunnel and configured to press down on the object and pull the object inside a scanner tunnel. A second drum extends substantially across an entire opening of the scanner tunnel and configured to press down on the object and pull the object from the scanner tunnel. A radiation shield covers an opening of the scanner tunnel. Sensors detects a type of object to be scanned and to control the first drum according to the type of object to be pulled inside the scanner tunnel.
