  • Patent number: 7567647
    Abstract: A system includes emission of first radiation from a plurality of radiation sources disposed in a fixed relationship to each other, the first radiation emitted from a first plurality of locations defining a first array geometry. A first set of projection images is acquired based on the emitted first radiation and digital tomosynthesis is performed on the first set of projection images to generate a first cross-sectional image. Second radiation is emitted from the plurality of radiation sources disposed in the fixed relationship to each other, the second radiation emitted from a second plurality of locations defining a second array geometry. A second set of projection images is acquired based on the emitted second radiation, and digital tomosynthesis is performed on the second set of projection images to generate a second cross-sectional image. The first array geometry and the second array geometry differ in at least one of shape and size.

  • Patent number: 7486773
    Abstract: A system may include emission of megavoltage radiation from a megavoltage radiation source, acquisition of a first image using an imaging device while first megavoltage radiation is emitted from the megavoltage radiation source and while a plurality of elements is between the megavoltage radiation source and the imaging device, and determination of an amount of scatter radiation based at least on areas of the acquired image corresponding to the plurality of elements. In some aspects, at least one of the plurality of elements is substantially pointed toward a focal spot of the megavoltage radiation source.

  • Publication number: 20080303457
    Abstract: Some embodiments include an accelerator waveguide to generate an accelerated radiation beam, and a housing to house to accelerator waveguide. The housing may include an interface to couple the housing to and to decouple the housing from a movable support. Some aspects include coupling a first interface of a housing to a first interface of a movable support, and uncoupling the first interface of the housing from the first interface of the movable support, wherein the housing includes an accelerator waveguide to generate an accelerated radiation beam.

  • Patent number: 7046757
    Abstract: A method for separating and filtering noise caused by X-ray scatter contaminations from the primary signal component of the signal produced by the detector assembly of a radiographic imaging device employs a scatter removal screen or grating disposed between the object being imaged and the detector assembly. The grating has an absorption that varies periodically for varying the intensity of the X-ray radiation passed through the grating. This variation in intensity of the X-ray radiation causes the signal produced by the detector assembly to be amplitude modulated so that the frequency of the primary signal component is shifted from noise components of the signal caused by X-ray scatter contamination allowing the noise components to be filtered from the primary signal component so that scatter induced noise may be reduced or eliminated from the signal.
