| 摘要 |
The invention relates to a method of checking the beam generation means and beam acceleration means of an ion beam therapy system that comprises a grid scanner device, arranged in a beam guidance system, having vertical deflection means and horizontal deflections means for the vertical and horizontal deflection of a treatment beam perpendicular to its beam direction, with the result that the treatment beam is deflected by the grid scanner device to an isocentre of the irradiation site, and a specific area surrounding the isocentre is scanned, wherein the type of ion, the ion beam energy, the ion beam intensity and the blocking of the accelerator and also the means for terminating extraction are checked. |
