  • Publication number: 20230028350
    Abstract: The present application relates to a patient support apparatus for a radiotherapy device. The patient support apparatus comprises a support surface and abase. The patient support apparatus also comprises a first connection assembly connecting the surface and the base, the first connection assembly being connected to the surface at a first connection point, wherein the first connection assembly is coupled to a first driving mechanism configured to effect translation of the first connection point in a substantially vertical direction. The patient support apparatus also comprises a second connection assembly connecting the surface and the base, the second connection assembly being connected to the surface at a second connection point, wherein the second connection assembly is coupled to a second driving mechanism configured to effect translation of the second connection point in the substantially vertical direction.

  • Publication number: 20190209042
    Abstract: A system includes a patient support including an elongate patient support surface; a pair of locating tracks, each locating track having an inward facing surface, and an outward facing surface in which a series of spaced grooves are defined, the locating tracks being arranged such that a space for a locating bar is defined between the inward facing surfaces, and respective grooves of the outward facing surfaces of the pair of locating tracks are aligned with each other; and a locating bar. The locating bar comprises: a substantially rigid bar structure dimensioned to fit between the inward facing surfaces of the locating tracks; and an end fitting provided at each of opposing ends of the bar structure, each end fitting including an abutment surface, and a resilient locking formation configured to engage in one of the grooves of the respective locating track.

  • Patent number: 8870055
    Abstract: A package (1) manufactured in a single piece of a flexible sheet (2). The package (1) comprises a lid (3) that can be opened and re-closed. The lid (3) is integrated with the package (1). The lid (3) is joined to the package 81) along a perforation line (5). The lid (3) has side walls (7a-d) of double-folded sheet material folded downwards along the perforation line (5) and then folded back upwards. There are cuts (8a, b) in the perforation line (5) in distal opposite ends thereof such that loose lid flaps (11 a, b) are provided on each side of the sheet (2) when the package (1) is folded along a longitudinal side, wherein a loose corner (12) is provided in the lid (3). The package (1) comprises a lid (3) that can be opened by a user a first time tearing off the lid (3) from the package (1). The package is provided with transverse tear-off strips (13) arranged around the package (1). The lid can be put back to reclose the package (1), also after partial drawing of the product.

  • Patent number: 8653444
    Abstract: A method and a calibration system for calibrating a measurement tool for measuring the radiation in a radiation system, such as a radiation therapy system, are provided. The measurement tool, including a holder and at least one photodiode element, is adapted to be mounted in a positioning unit of the radiation system. The radiation sensitive volume of the photodiode element is embedded in a light transparent coating transparent for, for instance, light in the visible spectrum. Thereby, the position of the sensitive volume can easily be determined or calculated with high accuracy relative to the holder on which the photodiode element is arranged, from which the position of the sensitive volume can be determined or calculated in relation to the positioning unit of the radiation system.

  • Publication number: 20050102248
    Abstract: A proposition (100) is obtained from a source (102). The process steps (104, 106, 108, 110) are then conducted and the results therefrom are stored in a storage unit (112). Information about a proposition is retrieved from the source in order to specify the proposition into non-ambiguous causal statements that are easy to agree on. Ultimately, this information is transferred into a logic map that graphically represents the initiative and serves as a guide to the management and evaluation of the project. Particularly, the logic map (12) has a context (14). An input (16) is linked to an effect (20) and a goal or goals (24, 25).
