    Abstract: Embodiments of the present invention provide a weighing method of a touchscreen terminal, and a touchscreen terminal. When a to-be-weighed object is placed in a preset area of a touchscreen of a touchscreen terminal, a reported first capacitance value and reported coordinates of a compensation point are obtained. The first capacitance value is compensated according to a compensation relationship, the coordinates of the compensation point, and the first capacitance value to obtain a second capacitance value. In this way, no additional external structure is needed for the touchscreen terminal, making the touchscreen terminal convenient to carry.

    Abstract: A method and apparatus for displaying a three-dimensional radiograph in a security scanner. A first X-ray image of an object is generated by the security scanner from a first viewpoint. A second X-ray image of the object is generated by the security scanner from a second viewpoint. The first X-ray image and the second X-ray image form a stereogram. The stereogram is displayed by the security scanner on a display system for the security scanner such that a first eye of a viewer sees the first X-ray image in the stereogram and a second eye of the viewer sees the second X-ray image in the stereogram. A parallax between the first viewpoint and the second viewpoint in the stereogram results in a three-dimensional visualization of the object on the display system for the security scanner.

In order to provide an improved fluent work flow for X-ray viewing with an improved visual perception of depth information, it is provided to generate an electron beam from a cathode arrangement towards a target area of an anode; to deflect the electron beam such that the electron beam hits the anode at different target spots (94a, 94b), wherein the variation is provided as gradual variation of an impinging direction of the electrons such that a stepless transition between monoscopic and stereoscopic viewing is provided. In the monoscopic viewing, X-ray radiation is generated from a single focal spot position, and wherein in the stereoscopic viewing, X-ray radiation is generated from two focal spot positions spaced apart from each other in a first stereo-direction transverse to a viewing direction (92).

  • Publication number: 20150036905
    Abstract: A 3D result image of an object is reconstructed from a set of X-ray two-dimensional projections of the object. A 3D reference image of the object is reconstructed by employing a compressed sensing technique based on at least some of the 2D projections at a reference motion state of the object. By employing an algebraic and/or analytic reconstruction technique, 3D intermediate images are reconstructed for various motion states of the object. The 3D intermediate images are registered with the 3D reference image to obtain spatial transformations for the various motion states of the object. Based on the spatial transformations, the 3D intermediate images are transformed to a joint phase and combined to obtain the 3D result image.

  • Publication number: 20140371513
    Abstract: A computing system determines a full motion range of a target, wherein the full motion range of the target defines an internal target volume (ITV). The computing system identifies a partial motion range of the target, wherein the partial motion range is a subset of the full motion range of the target. The computing system generates a partial-ITV based on the identified partial motion range, wherein the partial-ITV is a volume swept by the target as the target moves through the partial motion range, the partial-ITV being smaller than the ITV. The computing system generates a treatment plan to deliver treatment to the partial-ITV.

  • Patent number: 8897599
    Abstract: An imaging system comprises a transmitter (24, 25), a receiver (24, 25, 21), and a controller (20) for directing the transmitter and the receiver to scan an object in a volume. The controller determines which sub-volumes of the volume the object is located within and then performs a fine scan in those sub-volumes. This reduces overall scanning time. The controller (20) may compare a received signal sample magnitude from the initial scan with a threshold to make the decision. The initial scan may be performed with a spot size to include only one or more particular volume elements within at least some of the sub-volumes.
