  • Multi-axis dynamic tracking for radiation therapy
    Patent number: 9833636
    Abstract: A radiation device directs a beam of radiation onto a target. The beam can be adjusted using, for example, a control for setting beam shape and a control for setting beam intensity. The target is supported on a surface that can be adjusted using, for example, a control for setting surface position and a control for setting a speed for moving the surface. Controls are selected to adjust the beam and the surface cooperatively in order to compensate for movement of the target.
    Type: Grant

  • Six degrees of freedom motion platform
    Patent number: 9091391
    Abstract: A motion platform includes a base, a platform, and a suspension supporting the platform above the base. Strings preload the platform toward the base while the suspension pushes the platform away from the base. Actuators pull and release the strings to manipulate the platform in multiple degrees of freedom.

  • System and method for measuring X-ray beam profile using an area detector
    Patent number: 8983165
    Abstract: The claimed subject matter describes a novel technique to measure the beam profile using an area detector. In one embodiment, a set of one-dimensional beam profile measurements is performed by taking two images under the same source conditions but at two different positions of the detector, with each position of the detector shifted by a certain distance in the direction corresponding to the direction of the one-dimensional profile measurement. In further embodiments, a set of two-dimensional beam profile measurements is achieved by determining a second set of one-dimensional profiles from the same sampling points in a second direction and building a two-dimensional map of the beam profile by correlating the first one-dimensional profile measurement with the second one-dimensional profile measurement.
