  • Patent number: 10850128
    Abstract: A device for performing tomosynthesis in real time is described. Multiple imaging sources (such as x-ray sources) may be energized in parallel and collimated towards a field of view. Objects within the field of view cast shadows onto one or more detectors. An imaging system may read the one or more detectors and acquire multiple views corresponding to the multiple imaging sources to produce a reconstructed image of an object of interest. From this reconstructed image, a target of the radiation therapy can be located, and the delivery of the radiation can be adjusted, as needed. The approach provides a real-time tomosynthesis design that can produce enhanced contrast for guidance of, for example, lung tumor treatment. Higher frame rates can be achieved to better compensate for changes in the position of the target during radiation therapy due to, for example, respiratory or cardiac motion.

  • Patent number: 8901519
    Abstract: The invention concerns a device and a process for adjusting the range of an ion beam, in particular for irradiation in tumor therapy. For this purpose, first the reference position of a target volume to be irradiated is determined. Subsequently, the range of an ion beam is configured such that said beam is adjusted to the reference position of the target volume, in such a manner that the Bragg peak, i.e. the maximal energy loss and thereby the maximal damage occurs in the region of the target volume which is to be destroyed. In the case that it has been determined that the reference position has been altered by a movement of the target volume, the ion beam is then deflected from the beam axis such that the ion beam is directed to various regions of a range modulator, in order that the ion beam experience a correspondingly adjusted energy loss in passing through the range modulator.

    Abstract: A method of delivering radiation in a session includes delivering radiation towards a patient using a radiation system, wherein the radiation is delivered based at least in part on a physiological phase or a position of the patient, after the radiation is delivered, changing a configuration of the radiation system, wherein the act of changing the configuration is performed independent of at least one motion of the patient, and delivering additional radiation towards the patient after the configuration of the radiation system is changed, wherein the acts of delivering radiation and the act of changing the configuration are performed in response to a processor executing a treatment plan that prescribes a plurality of packages and a transition, the transition prescribing the act of changing the configuration of the radiation system when no radiation is being delivered by the radiation system.

  • Patent number: 8269195
    Abstract: A patient alignment system for a radiation therapy system. The alignment system includes multiple external measurement devices which obtain position measurements of components of the radiation therapy system which are movable and/or are subject to flex or other positional variations. The alignment system employs the external measurements to provide corrective positioning feedback to more precisely register the patient and align them with a radiation beam. The alignment system can be provided as an integral part of a radiation therapy system or can be added as an upgrade to existing radiation therapy systems.

  • Patent number: 8229069
    Abstract: A radiosurgery system is described that is configured to deliver a therapeutic dose of radiation to a target structure in a patient. In some embodiments, inflammatory ocular disorders are treated, specifically macular degeneration. In some embodiments, other disorders or tissues of a body are treated with the dose of radiation. In some embodiments, the target tissues are placed in a global coordinate system based on ocular imaging. In some embodiments, the target tissues inside the global coordinate system lead to direction of an automated positioning system that is directed based on the target tissues within the coordinate system. In some embodiments, a treatment plan is utilized in which beam energy and direction and duration of time for treatment is determined for a specific disease to be treated and/or structures to be avoided. In some embodiments, a fiducial marker is used to identify the location of the target tissues.

  • Patent number: 8165660
    Abstract: A system for planning a percutaneous procedure provides a patient 3-dimensional image data set within which an instrument trajectory is defined, for example, by selecting a skin entry point and a target point. A line, or “planned path,” is generated between the points. The system determines whether the path can be targeted so an optical axis of a movable arm coincides with the path so that a laser can be used for instrument guidance or whether a planned path can be targeted so that a C-arm can be made to coincide with the path so that the extension of the path is projected onto a radiation detector, using x-ray radiation. If neither laser guidance or x-ray guidance can be used, the path is replanned.

  • Patent number: 8144832
    Abstract: The invention comprises an X-ray tomography method and apparatus used in conjunction with multi-axis charged particle or proton beam radiation therapy of cancerous tumors. In various embodiments, 3-D images are generated from a series of 2-D X-rays images; the X-ray source and detector are stationary while the patient rotates; the 2-D X-ray images are generated using an X-ray source proximate a charged particle beam in a charged particle cancer therapy system; and the X-ray tomography system uses an electron source having a geometry that enhances an electron source lifetime, where the electron source is used in generation of X-rays. The X-ray tomography system is optionally used in conjunction with systems used to both move and constrain movement of the patient, such as semi-vertical, sitting, or laying positioning systems. The X-ray images are optionally used in control of a charged particle cancer therapy system.
