    • A quality control accessory (QC accessory) is provided which is adapted for use in linear accelerator quality control or in verification of an arbitrary isocentric radiation treatment plan of a patient or radiation sensitive body. The accessory includes an absorber, a detector and an optional orientation device. The absorber is rotationally symmetric, preferably spherical or hemispherical. The detector is adapted to be fixed in a stationary spatial relationship with respect to the absorber. The optional orientation device is adapted to maintain the two dimensional detector (2d detector) and the absorber in a fixed relative spatial relationship with respect to the beam focus of the linear accelerator, when the gantry is rotated, so that the central axis of the beam is essentially orthogonal to the 2d detector and the phantom axis of symmetry is parallel to or aligned with the central axis of the gantry rotation axis

    • Methods, devices and systems for performing quality assurance on an interrupted radiotherapy treatment are disclosed. The method includes measuring a first delivered dose distribution of an uninterrupted treatment, measuring a second delivered dose distribution of the same treatment that has been interrupted, and obtaining first and second images that represent the first and second delivered dose distributions, respectively. The method includes registering the first and second images so that they are mapped into the same physical space, and comparing the first and second images to determine any differences between the two images and hence any differences between the uninterrupted and the interrupted radiation treatments. The methods are useful in discerning the affects of system interruption on complex conformal radiation therapies, including IMRT.

    • The present invention relates to a method for monitoring an isocentre and a positioning device for patients, said positioning device and isocentre pertaining to an ion-beam therapy system that comprises a raster scanner device which is arranged in a beam guiding system. Said raster scanner device has vertical and horizontal deflection means for vertically and horizontally deflecting a treatment beam in a perpendicular manner in relation to the direction of said beam in such a way that the treatment beam is deflected onto an isocentre of the irradiation location by means of the raster scanner device. The treatment beam scans a certain surface which surrounds the isocentre, whereby the isocentre and the positioning device for patients are monitored and the positioning device for patients is provided with a patient table that can be pivoted around a pivoting axis. For verification, a target within the spherical phantom is represented by means of a specific monitoring body and the centre of the monitoring body is visibly represented by means of several image-producing methods. The ion-beam therapy arrangement is inspected and/or maintained when the measuring results of the spatial position of the centre in relation to the image-giving methods exceed a given intervention threshold.
