  • Publication number: 20190151018
    Abstract: A pulmonary treatment system includes a compact configuration for delivery to a first airway of a patient. An energy delivery system of the pulmonary treatment system delivers energy to target tissue in or along an airway wall of the first airway to reduce airway resistance in a second airway distal to the first airway. The pulmonary treatment system protects tissue in the airway wall of the first airway located between the target tissue and the energy delivery system by at least one of thermodynamically cooling, circulating a liquid coolant through the pulmonary treatment system, and shielding a portion of the energy delivery system.

  • Publication number: 20080021308
    Abstract: A leadless marker for localizing the position of a target within a patient. In one embodiment, the marker includes a casing, a resonating circuit, and a ferromagnetic element. The casing is configured to be positioned at a selected location relative to a target site in the patient; the casing, for example, can be configured to be permanently or semi-permanently implanted into the patient. The resonating circuit has an inductor within the casing comprising a plurality of windings of a conductor, but it does not have external electrical lead lines extending through the casing. The ferromagnetic element is at least partially within the inductor. The ferromagnetic element has a volume such that when the marker is in an imaging magnetic field having a field strength of 1.5 T and a gradient of 3 T/m, then the force exerted on the marker by the imaging magnetic field is not greater than gravitational force exerted on the marker.

  • Publication number: 20080001756
    Abstract: A system for generating a magnetic field for excitation of a leadless marker assembly. The system of at least one embodiment includes a source generator that generates a plurality of alternating electrical signals each having an independently adjustable phase. A plurality of excitation coils are configured to simultaneously receive a respective one of the alternating electrical signals at a selected phase to generate a magnetic field. The phase of the alternating electrical signal for each excitation coil is independently adjustable relative to the phase of the alternating electrical signal for the other excitation coils so as to adjust the magnetic field from the respective coil. The magnetic fields from the excitation coils combine to form a spatially adjustable excitation field for excitation of the remote leadless marker assembly.

  • Publication number: 20070057794
    Abstract: A miniature resonating marker assembly that includes, in one embodiment, a ferromagnetic core, a wire coil disposed around the core, and a capacitor connected to the wire coil adjacent to the magnetic core. The core, coil, and capacitor form a signal element that, when energized, generates a magnetic field at a selected resonant frequency. The magnetic field has a magnetic center point positioned along at least one axis of the signal element. An inert encapsulation member encapsulates the signal element therein and defines a geometric shape of the resonating marker assembly. The geometric shape has a geometric center point substantially coincident with the magnetic center point along at least a first axis of the signal element. The shape and configuration of the assembly also provides for a miniature signal element specifically tuned to resonate at a selected frequency with a high quality factor.

  • Publication number: 20060100509
    Abstract: A facility for processing data is described. The facility receives a stream of digital location indications, each location indication identifying a location of a patient while undergoing radiation therapy. In response to each location indication of the string, in substantially real-time relative to the receipt of the position indication, the facility performs an action responsive to the location indication.

  • Publication number: 20060093089
    Abstract: Systems and methods for treating a lung of a patient. One embodiment of a method comprises positioning a leadless marker in the lung of the patient relative to the target, and collecting position data of the marker. This method further comprises determining the location of the marker in an external reference frame outside of the patient based on the collected position data, and providing an objective output in the external reference frame that is responsive to movement of the marker. The objective output is provided at a frequency (i.e., periodicity) that results in a clinically acceptable tracking error. In addition, the objective output can also be provided at least substantially contemporaneously with collecting the position data used to determine the location of the marker.

  • Publication number: 20060079764
    Abstract: Systems and methods for tracking targets in real time for radiation therapy and other applications. In one embodiment, a method includes collecting position information of a marker implanted within a patient at a site relative to the target at a time tn, and providing an objective output indicative of the location of the target based on the position information collected at time tn. The objective output is provided to a memory device, user interface, and/or radiation delivery machine within 1 ms to 2 seconds of the time tn when the position information was collected. This embodiment of the method can further include providing the objective output at a periodicity of 10-200 ms during at least a portion of a treatment procedure.

  • Publication number: 20060078086
    Abstract: A facility for facilitating custom radiation treatment planning is described. During a distinguished radiation treatment session for a patient, the facility collects data indicating positioning of a predefined treatment site of the patient relative to a target treatment location throughout the distinguished radiation treatment session. The facility associates the collected positioning data with data describing one or more other aspects of the distinguished radiation treatment session. The facility provides the associated data to a treatment planning facility to determine a treatment plan for future radiation treatment sessions for the patient.

  • Publication number: 20060074301
    Abstract: An integrated radiation therapy process comprises acquiring first objective target data related to a parameter of a target within a patient by periodically locating a marker positioned within the patient using a localization modality. This method continues with obtaining second objective target data related to the parameter of the target by periodically locating the marker. The first objective target data can be acquired in a first area that is apart from a second area which contains a radiation delivery device for producing an ionizing radiation beam for treating the patient. The localization modality can be the same in both the first and second areas. In other embodiments, the first objective target data can be acquired using a first localization modality that uses a first energy type to identify the marker and the second objective target data can be obtained using a second localization modality that uses a second energy type to identify the marker that is different than the first energy type.

  • Publication number: 20050261570
    Abstract: A system and method for accurately locating and tracking the position of a target, such as a tumor or the like, within a body. In one embodiment, the system is a target locating and monitoring system usable with a radiation delivery source that delivers selected doses of radiation to a target in a body. The system includes one or more excitable markers positionable in or near the target, an external excitation source that remotely excites the markers to produce an identifiable signal, and a plurality of sensors spaced apart in a known geometry relative to each other. A computer is coupled to the sensors and configured to use the marker measurements to identify a target isocenter within the target. The computer compares the position of the target isocenter with the location of the machine isocenter. The computer also controls movement of the patient and a patient support device so the target isocenter is coincident with the machine isocenter before and during radiation therapy.
