Abstract: The present invention provides system, devices, and methods for scanning an object while avoiding radiation exposure. For example, the present invention provides systems comprising a scanning device with input and output openings, and a safety sensor adjacent to the input or output opening that sends a signal that turns off or physically blocks electromagnetic radiation if the presence of an invading element (e.g., human hand) is detected by the safety sensor.

Abstract: A radiation tunnel of an X-ray test device is shielded in by means of a radiation protection curtain in order that no impermissible radiation emerges. The radiation protection curtain is constructed from plates which are connected to one another in a manner of a downwardly suspended flat-top chain and are produced from a plastics composite that absorbs X-rays.

Abstract: A device includes a radiation tunnel in which an X-ray source and a detector unit are disposed, the detectors of which are aligned with the X-ray source so as to detect transmitted radiation for detecting suspicious objects. Disposed in the radiation tunnel is a frame which can be moved over an examination region and has two supports which extend at a spacing parallel to each other and are rigidly connected to each other, the radiation source being secured on one vertical support and the detector unit being secured on the other vertical support.

Abstract: For examining objects, in particular for inspecting persons for suspicious items, devices having a scanning system for scanning the object and having an evaluating system are known. An optical marking system is provided, which indicates the position of an item classified as suspicious on the object itself or in a mirror image of the object by means of visible light.

Abstract: Among other things, one or more techniques and/or systems for selectively inhibiting radiation from being generated by a radiation source are provided. A radiation source comprises an electrically conductive gate situated between a cathode and an anode. When a voltage potential is created between the gate and the cathode, a flow of electrons between the cathode and the anode is mitigated, thus inhibiting radiation from being generated by the radiation source. When the voltage potential is removed or lessened, electrons may more freely flow between the cathode and the anode to generate radiation. In some embodiments, a calibration, such as a dark calibration, may be performed while the gate mitigates the flow of electrons. Moreover, in some embodiments, an accelerating voltage applied to the radiation source may be held substantially constant when radiation is generated as well as when radiation generation is inhibited.

Abstract: Systems and methods for modeling are provided. The method can include acquiring scan data associated with a plurality of x-ray projections of an item. The method can further include determining at least one closed boundary curve associated with the item. For example, the method can determine a first maximum area based on the scan data and determine at least one edge of the first maximum area. The method can further generate a model of the item using the closed boundary curve and a first material specific parameter for a material within the closed boundary curve. The method can utilize the model to generate computed scan data, compare the computed scan data to the scan data, and determine a goodness of fit. The method can further adjust the model of the item by altering at least one of the closed boundary curve and the material specific parameter.
