    摘要: The present invention provides methods and apparatus for safely managing the provision of radiotherapy treatment potentially in many different locations around the world. A database is formed comprising allowable ranges for each of a plurality of calibration settings in a calibration data set used to implement treatment plans in radiotherapy systems. Prior to treatment, the calibration settings of a proposed calibration data set are compared to these allowable ranges to see whether the treatment should be allowed to proceed. If one or more of the proposed calibration settings falls outside the allowable ranges, the therapy session may be stopped or prevented altogether.

    摘要: A scanning magnet (28, 29) of an irradiation nozzle (27) is controlled to irradiate the ion beam irradiated from a synchrotron accelerator to a target position P i,j of a spot i,j in a certain layer L i of a target volume, using a scanning control apparatus (40). A deviation D j between the target position P i,j and an actual irradiation position Pa i,j is obtained. Using the deviation D j , a systematic error Es i,j and a random error Er i,j of the actual irradiation position Pa i,j are obtained. Whether the systematic error Es i,j exists within a first permissible range of the systematic error Es i,j is determined. Whether the random error Er i,j exists within a second permissible range of the random error Er i,j is determined. When the systematic error Es i,j or the random error Er i,j is deviated from the permissible range, the irradiation of the ion beam to the target volume is stopped.

    摘要: There is presented a phantom (734) comprising a matrix and a plurality of particles embedded in said matrix, wherein said particles comprise optically stimulated luminescence material, wherein a size of the phantom along each and all of the three geometrical dimensions is at least 10 millimetre. In an embodiment, an attenuation coefficient of the phantom is equal to or less than 10 cm -1 at a wavelength, where optical stimulation of the particles can be carried out at said wavelength and/or where stimulated luminescence takes place.
