  • Patent number: 11426135
    Abstract: A multi-modality imaging system allows for selectable photoelectric effect and/or Compton effect detection. The camera or detector is a module with a catcher detector. Depending on the use or design, a scatter detector and/or a coded physical aperture are positioned in front of the catcher detector relative to the patient space. For low energies, emissions passing through the scatter detector continue through the coded aperture to be detected by the catcher detector using the photoelectric effect. Alternatively, the scatter detector is not provided. For higher energies, some emissions scatter at the scatter detector, and resulting emissions from the scattering pass by or through the coded aperture to be detected at the catcher detector for detection using the Compton effect. Alternatively, the coded aperture is not provided. The same module may be used to detect using both the photoelectric and Compton effects where both the scatter detector and coded aperture are provided with the catcher detector.

  • Patent number: 11409019
    Abstract: An X-ray imaging apparatus comprises a digital X-ray detector housed in a radiation shielded enclosure with multiple pinhole apertures in the front panel of the housing. An X-ray source illuminates a target and X-rays are backscattered towards the X-ray imaging apparatus. The multiple pinhole apertures arranged in a pattern so that each pinhole generates a respective pinhole image on the X-ray detector. The size of each image is controlled by the thickness of the front panel and the width of the pinhole aperture (acting as optical stops), and the distance to the X-ray detector, and these values are selected to prevent overlap between any pair of pinhole images on the X-ray detector. An image processor is used to generate a synthetic combined image of the object form the multiple pinhole images.

  • Patent number: 11399780
    Abstract: Methods and systems for stationary computed tomography are disclosed. The methods and systems include a gantry having alternating x-ray sources and x-ray detectors that are stationary during operation of the system. The gantry and pairs of x-ray sources and detectors substantially surrounds an object positioned inside the gantry during operation of the system. Dynamically adjustable collimators are positioned between the x-ray sources and the object. Each of the x-ray sources projects an x-ray beam through the collimators and through the object and the x-ray detectors receive the x-ray beam. The x-ray detectors include means for converting the x-ray beam to raw image data. One or more microprocessors control the x-ray sources and the process raw image data. A data storage device stores instructions, which upon execution by the microprocessor, control the x-ray sources and process the raw image data by converting the raw image data to a digital image.

  • Patent number: 11395926
    Abstract: The invention relates to a system for planning a radiation therapy treatment. The system obtains a first treatment plan generated in accordance with values of parameters quantifying an amount of radiation provided by radiation components, obtains an instruction to change a radiation dose delivered to at least one volume element, and directly calculates, for each of the radiation components, a change of the amount of radiation provided by the radiation component based on the instruction and based on the contribution of the radiation component to the radiation dose delivered to the at least one volume element. In order to observe upper and/or lower thresholds of the parameter values, the updated parameter values are calculated by iteratively adding the determined changes to the parameter values until a parameter value reaches the threshold or until the desired dose change is realized.
