METHOD FOR MONITORING AN ISOCENTRE AND A POSITIONING DEVICE FOR PATIENTS, SAID POSITIONING DEVICE AND ISOCENTRE PERTAINING TO AN ION-BEAM THERAPY SYSTEM |
摘要 |
The present invention relates to a method of checking an isocentre and a patient-positioning device of an ion beam therapy system that comprises a grid scanner device, arranged in a beam guidance system, having vertical deflection means and horizontal deflection 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 onto an isocentre of the irradiation site, and a specific area surrounding the isocentre is scanned, wherein a check of the isocentre and a patient-positioning device is carried out and the patient-positioning device comprises a patient table rotatable about an axis of rotation of the table. For the checking, a target point within a spherical phantom is represented by means of a special specimen body and the centre point of the specimen body is visibly represented by means of several image-forming methods. On departure of the measurement results in respect of the spatial position of the centre point under the image-forming methods from a predetermined intervention threshold, the ion beam therapy system is subjected to an inspection and/or maintenance. |
