Patent number: 11439847Abstract: 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.Type: GrantFiled: September 27, 2018Date of Patent: September 13, 2022Assignee: VARIAN MEDICAL SYSTEMS, INC.Inventors: Edward J. Vertatschitsch, Steven C. Dimmer, Timothy P. Mate, Eric Meier, Keith Seiler, J. Nelson Wright

Publication number: 20100282983Abstract: One embodiment of such a system comprises a sensor assembly mounted in a fixed location relative to a machine isocenter. According to another embodiment, the sensor assembly includes a fixed mounting bracket and an articulating arm allowing movement of the sensor assembly while allowing translation of the sensor assembly location with reference to the machine isocenter According to still another embodiment, the sensor assembly is positioned in a fixed relationship relative to the patient support assembly, mounted below the patient support assembly, as an overlay on the patient support assembly or integral to and forming a portion of the patient support assembly. The sensor assembly location is referenced to the machine isocenter through the relation of the table to the machine isocenter or through an independent locating system for the sensor assembly. According to yet another embodiment, the sensor assembly is located relative to machine isocenter by conventional imaging techniques.Type: ApplicationFiled: July 14, 2008Publication date: November 11, 2010Inventors: J.

Patent number: 5467942Abstract: An optical sensing system for sensing the temperature at a first location, including: electro-optical unit for producing a modulated optical signal and a light guide unit for receiving and transmitting the modulated optical signal along an optical path. The optical system further includes temperature sensing fiber which receives and guides the modulated optical signal along a temperature sensing optical path. One portion of the modulated optical signal serves as a reference optical signal and another portion of the modulated optical signal serves as a target optical signal. The optical sensor system also has a transducing unit, which receives the reference optical signal, the target optical signal having first and second time delays with respect to a chirped rf signal from the electro-optical unit. The transducing unit produces a multi-frequency electrical signal which includes a first frequency corresponding to the first time delay a second frequency corresponding to the second time delay.Type: GrantFiled: October 1, 1993Date of Patent: November 21, 1995Assignee: The Boeing CompanyInventors: Gregory L.

Patent number: 5422477Abstract: An optical sensing system with a rotation sensor head for sensing the rotation of a rotatable object while simultaneously sensing the position of a displaceable object with a position sensor head. An electro-optical unit outputs a modulated optical signal and a chirped rf signal. The envelope of the modulated optical signal has a phase that has a known relation to the phase of the chirped rf signal. The electro-optical unit is coupled to a light guide element and receives and transmits the modulated optical signal along an optical path for reflection off a disk secured to the rotatable object in order to provide a rotation sensing optical signal. A transducing unit receives the rf signal at one input and has another input optically coupled to receive the rotation sensing optical signal while simultaneously receiving position sensing optical signals from the position sensor heads.Type: GrantFiled: October 1, 1993Date of Patent: June 6, 1995Assignee: The Boeing CompanyInventors: Michael de La Chapelle, Edward J.

Patent number: 5276455Abstract: A phased array antenna structure has a distribution network, and a composite of feed, module, and antenna honeycomb structures. The distribution network distributes or collects electromagnetic (EM) energy. The feed honeycomb structure is positioned adjacent the distribution network and connected to receive the EM energy from the distribution network or to distribute EM energy to the distribution network. The module honeycomb structure is positioned adjacent the feed honeycomb structure so as to receive EM energy from the feed honeycomb structure or to transmit EM energy to the feed honeycomb structure. The antenna honeycomb structure is positioned adjacent the module honeycomb structure on a side opposite the feed honeycomb structure so as to receive EM energy from the module honeycomb structure or to transmit EM energy to the module honeycomb structure. Each of the feed, module and antenna honeycomb structures have a plurality of aligned waveguides for transmitting EM energy therealong.Type: GrantFiled: May 24, 1991Date of Patent: January 4, 1994Assignee: The Boeing CompanyInventors: George W.

Patent number: 4939527Abstract: A distribution network for a modified space-fed phased array antenna consists of a planar array of radiating slots distributed along a coplanar wall in each of an ensemble of parallel waveguides. This waveguide ensemble is fed or excited by an orthogonal waveguide or waveguides, through a row of slots in a wall common to the excitation waveguides and the parallel waveguide ensemble, one slot per waveguide. A predetermined amplitude distribution is achieved in the plane parallel to the axis of the exciting waveguide by adjusting the coupling value of each exciting slot, and in the orthogonal plane by adjusting the displacement of the radiating slots from the center line of the waveguides, and by adjusting slot width, length, and geometry. Such an array of slots is used to feed the inside face of a quasi-space-fed antenna array having identical, individual electronics modules.Type: GrantFiled: January 23, 1989Date of Patent: July 3, 1990Assignee: The Boeing CompanyInventors: Bernard J.
