| 摘要 |
The invention concerns a machine for intraoperative radiation therapy or IORT (Intra Operative Radio Therapy), comprising a mobile body, provided with at least two driving wheels ( 21, 22 ) and at least an idle wheel ( 24, 25 ), each driving wheel ( 21, 22 ) being operated by a corresponding moving engine, the machine comprising a radiating head ( 23 ) connected to the body, apt to emit am electron beam, the machine being characterised in that it further comprise handling means ( 19 ) which are integral with the radiating head ( 23 ), engine means for moving the radiating head ( 23 ), apt to impress to the radiating head ( 23 ) at least a vertical translation motion, said handling means ( 19 ) comprising at least three bidirectional sensors ( 20 ), apt to measure both a traction stress and a compression stress, each one of which sends to a control processor an electric signal which is proportional to a measured stress which is orthogonal to the sensor, said control processor operating the moving engines of each of said at least two driving wheels ( 21, 22 ) and the engine means for moving the radiating head ( 23 ) proportionally to the stresses which are measured by said at least three bidirectional sensors ( 20 ).
