  • Systems and methods for quantifying radiation beam conformity
    Patent number: 10729920
    Abstract: A method for quantifying radiation beam conformity includes: obtaining first information regarding a prescribed aperture; obtaining second information regarding an actual aperture defined by components of a collimator; and determining, using a processing unit, a metric based on the first information regarding the prescribed aperture and the second information regarding the actual aperture, wherein the metric indicates an amount of over-exposed aperture area, an amount of under-exposed aperture area, or both, and wherein the processing unit comprises one or more input for receiving the first and second information, and comprises a metric determination module configured to determine the metric based on the first information and the second information.

  • 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.
