Patent number: 10799718Abstract: A system and method of integrating a first computer and a second computer is disclosed. The first computer executes a software application having a graphical user interface. The second computer renders the graphical user interface, receives an identification of an event that has occurred in the software application, and identifies an action to be performed by the second computer in response to the occurrence of the event, the action being identified from a predefined sequence of actions. The second computer performs the identified action to modify the rendering of the graphical user interface.Type: GrantFiled: February 25, 2016Date of Patent: October 13, 2020Assignee: ELEKTA LIMITEDInventor: Adrian Maxwell Smith

Patent number: 10576301Abstract: A fluorescing marker is used in order to mark (for example) a leaf of a multi-leaf collimator and/or the reference points within the field of view. The markers are illuminated with light tuned to cause the markers to fluoresce at a wavelength different to that of the illuminating light. The fluorescence is then detected by a camera. This method allows the image to be captured by the camera with increased contrast. Accordingly, the present invention provides a multi-leaf collimator for a radiotherapeutic apparatus, comprising at least one leaf having a fluorescent marker. The fluorescent marker will usually emit light of a wavelength longer than the incident light, allowing suitable filters to be provided in order to distinguish the light emitted by the markers. A suitable material for use in the fluorescent markers is ruby. The present invention also provides a radiotherapeutic apparatus comprising a multi-leaf collimator as defined above, and a camera arranged to view the fluorescent markers.Type: GrantFiled: July 20, 2017Date of Patent: March 3, 2020Assignee: Elekta AB (publ)Inventors: Shakil Ahmed Awan, Adrian Maxwell Smith

Patent number: 9955241Abstract: An apparatus for enabling a first device to identify a second device comprises a first interface and a second interface. Each interface is configured to allow communication between the first device and the second device, and the first interface is distinct from the second interface. The apparatus further comprises one or more controllers configured to receive a first identifier from the second device via the first interface. If the first identifier has a predetermined value, the controllers receive a second identifier from the second device via the second interface. The controllers identify the second device using the second identifier.Type: GrantFiled: February 21, 2017Date of Patent: April 24, 2018Assignee: ELEKTA LIMITEDInventor: Adrian Maxwell Smith

Patent number: 8995617Abstract: The ability to provide a fine resolution variation in the dose rate of radiotherapeutic apparatus would allow delivery times of Volumetric Modulated Arc Therapy (VMAT) and related techniques to be reduced significantly. A radiotherapeutic apparatus is described, comprising a source of radiation able to issue pulses of radiation at a base frequency, and a control apparatus arranged to permit pulses provided these match a pulse pattern chosen to achieve a selected time-averaged power level, the chosen pulse pattern being one selected from a plurality of pulse patterns that include patterns consisting of trains of pulses that include, relative to the base frequency, at least every nth and every mth pulse where n?m and the nth and mth pulses are non-coincident. Essentially, such an apparatus issues a pulse if it is the nth or the mth or the kth (etc) where n, m, k . . . are selectable independently.Type: GrantFiled: October 1, 2010Date of Patent: March 31, 2015Assignee: Elekta AB (publ)Inventors: Kevin Brown, Adrian Maxwell Smith

Patent number: 8467499Abstract: A multi-leaf collimator for a radiotherapy apparatus comprises a plurality of elongate leaves mounted in a carriage, the carriage being mounted on a substrate, wherein the leaves are independently moveable relative to the carriage in a longitudinal direction, and the carriage is moveable in that direction relative to the substrate, and a control apparatus is arranged to receive a signal representing leaf positions relative to the substrate and to control the leaf positions relative to the carriage and the carriage positions relative to the substrate so as to achieve those leaf positions relative to the substrate. Most MLCs sense the current positions of the leaves relative to the substrate. The control apparatus can therefore compare the current leaf positions to the signaled leaf positions, and move the leaves and the carriage accordingly. A corresponding method is also disclosed.Type: GrantFiled: April 21, 2008Date of Patent: June 18, 2013Assignee: Elekta AB (Publ)Inventors: Mark Alexander Furth, Adrian Maxwell Smith

Publication number: 20110049396Abstract: A multi-leaf collimator for a radiotherapy apparatus comprises a plurality of elongate leaves mounted in a carriage, the carriage being mounted on a substrate, wherein the leaves are independently moveable relative to the carriage in a longitudinal direction, and the carriage is moveable in that direction relative to the substrate, and a control apparatus arranged to receive a signal representing leaf positions relative to the substrate and being arranged to control the leaf positions relative to the carriage and the carriage positions relative to the substrate so as to achieve those leaf positions relative to the substrate. By allowing the carriage to be driven concurrently with the leaves, the speed of movement of the carriage can be added to that of the leaves. In this way, where leaves are required to make a long traverse they can do so more quickly.Type: ApplicationFiled: April 21, 2008Publication date: March 3, 2011Applicant: ELEKTA AB (PUBL)Inventors: Mark Alexander Furth, Adrian Maxwell Smith
