Abstract: A system and method for improving and/or repairing data structures in databases or other structured data such as in project management computer software. Such project management software includes complicated data structures, which are prone to developing inconsistencies and errors over time. The system or method takes snapshots of datasets from the project management software at periodic points in time, ingests the data and maps it to internal data objects. This allows an analytics engine to efficiently perform a range of validation checks for anomalies and other issues that contravene Agile rules by identifying dependencies between individual work task entities and creating links in the data objects to other data objects representing those dependencies. Thus, the system may indicate to the user issues with the data, automate repair of the data structures and provide tools for the user to quicky and efficiently fix the source data.

Abstract: In various embodiments, a system for controlling radiotherapy equipment in a treatment environment includes a controller for receiving, from one or more image capture devices, data indicating the position of one or more objects in the treatment environment. Based on the position data, the controller defines one or more exclusionary zones from which the radiotherapy equipment is excluded. Each zone has a buffer area surrounding one or more of the objects. The controller further directs the radiotherapy equipment such that a radiotherapy treatment plan is delivered without the equipment entering into the exclusionary zones.

Abstract: We provide a radiotherapeutic apparatus comprising a patient support, magnetic coils disposed around the patient support for creating a magnetic field therewithin, a radiation source producing a beam of radiation directed toward the patient support and mounted on a rotatable support thereby to rotate the radiation source around the patient support, a slip ring for conveying electrical power to the radiation source and located around the patient support, including at least one electrical interruption therein. This creates a slip ring in which there is no continuous circumferential path, and one in which the current is therefore forced to take a route via one side or the other.

Abstract: An apparatus has a patient support, a rotatable gantry supporting a source of imaging radiation, and a radiation detector that operates in a cyclical pattern of an exposure phase followed by a readout phase. For a first detector cycle in which the gantry has a first angle of rotation, the source of radiation is controlled to emit a first radiation beam pulse during the exposure phase, and respective first imaging data is read out during the readout phase. For a second, subsequent detector cycle, it is determined if the gantry has rotated through at least a threshold angular displacement relative to said first angle of rotation, and if so, the source of radiation is controlled to emit a second radiation beam pulse during the exposure phase, and respective second imaging data is read out during the readout phase.

Abstract: In radiotherapy apparatus comprising an imager for the MV beam and a separate kV imaging system, it is common for there to be significant artifacts in the kV image arising from the MV pulse. We disclose such a radiotherapy apparatus which is adapted to (i) cause the therapeutic source to emit radiation while keeping the diagnostic source inactive, (ii) read an image from the detector associated with the therapeutic source, (iii) cause the diagnostic source to emit radiation and while keeping the therapeutic source inactive, (iv) read an image from the detector associated with the diagnostic source, and (v) repeat as necessary. The control unit is preferably adapted to, at steps (ii) and (iv), read an image from both of the detectors, or to clear the “inactive” detector. The detectors are ideally flat-panel detectors, capturing a two-dimensional image.
