  • Patent number: 10806948
    Abstract: A radiation therapy apparatus determines a set of angles that have a tracking quality metric value that satisfies a tracking quality metric criterion. During an alignment phase or a treatment phase for a treatment stage of a target by the radiation therapy apparatus, the radiation therapy apparatus performs selects at least a first angle and a second angle from the set of angles for a first rotation of the gantry. The radiation therapy apparatus generates, using an imaging device mounted to the gantry, a first tracking image of the target from the first angle during the first rotation of the gantry. The radiation therapy apparatus generates, using the imaging device, a second tracking image of the target from the second angle during the first rotation of the gantry. The radiation therapy apparatus performs the target tracking based on the first tracking image and the second tracking image.

  • Patent number: 10119923
    Abstract: Methodologies, systems, apparatus, and non-transitory computer-readable media are described herein to facilitate acquisition of volumetric data and volumetric image reconstruction. An imaging system can be configured to transport an object at a speed relative to the scan path of an X-ray source such that insufficient measurement data is collected for classically complete geometrical coverage. Iterative image reconstruction techniques may be used to generate volumetric images based on measured volumetric data of at least a portion of the object.

  • Patent number: 10107768
    Abstract: An imaging system operative for providing a volumetric molecular image of an object is disclosed. The imaging system interrogates the object with structured x-ray radiation while continuous relative motion between the object and source is induced during a measurement period. As the radiation passes through the object, the radiation scatters based on the molecular composition within the object, and the scattering changes as a function of time due to the relative motion between the source and object. Coherent scatter radiation is detected and processed to reconstruct an estimate of the three-dimensional molecular structure of the object using a reconstruction algorithm, such as maximum likelihood estimation.

  • Patent number: 10098607
    Abstract: A tomographic device includes a recording unit with a central system axis, a patient couch movable along the system axis and also a radiation source and a radiation detector interacting with the radiation source. The inventors have recognized that a rapid, precise and reliable positioning of a first recording area can be achieved by the positioning being based on a trained model, wherein the model has been trained with training positions. The tomographic device therefore includes a computing unit, which is designed for calibration of a first position of the first recording area relative to the recording unit based on the trained model. Furthermore the tomographic device includes a control unit for positioning the first recording area in the first position by moving the patient couch relative to the recording unit. The tomographic device is designed for a first tomographic recording of the first recording area in the first position.

  • Patent number: 10092251
    Abstract: The plan CT is described to generate dual energy (DRR) that stimulates the treatment time radiographs in order to prospectively evaluate the angles in which issues for the template matching algorithm are present, and thus the visibility of the tumor. The present invention uses template matching to quantify the “trackability” of the target from different angles or directions. The peak-to-side lobe ratio is used to measure trackability. The results of this process influence treatment planning. For example, based on the outcome, either less or no dose is planned for the angles in which the location of the templates cannot be verified and thus, the tumor.

  • Patent number: 10064584
    Abstract: The invention relates to a combined x-ray and optical (light-based) tomographic imaging system that provides functional information at greater resolution than can be achieved by optical tomography alone. The system is configured with one or more x-ray sources, x-ray detectors, light sources, and light detectors arranged on a gantry which rotates about an imaging chamber containing the object to be imaged. The system thereby allows both x-ray radiation and light to be directed into the object at multiple locations. Processing methods of the invention go beyond simple co-registration of images obtained from two or more imaging techniques. Both x-ray data and light data are used together in optical tomographic reconstruction to create the tomographic image, thereby allowing a more accurate and/or higher resolution final image.
