| 摘要 |
The invention relates to a device for radiation treatment of proliferative tissue surrounding a cavity in an animal body comprising at least an inflatable balloon system having a balloon wall for placement in said cavity; a supportive probe having an elongated body with a distal end connected with said inflatable balloon system and a proximal end remaining outside said cavity; inflation means for inflating and deflating said balloon system with a pressurized medium; radiation delivering means for placing at least one energy emitting source within said cavity for performing said radiation treatment. It is an object of the invention to provide a device for radiation treatment of proliferative tissue surrounding a cavity in an animal patient body according to the above preamble capable in controlling the real, actual status of the inflated balloon system present inside said body cavity, especially when said device is utilized with an after loading apparatus. The device is according to the invention characterized in that said device comprises monitoring means for monitoring the inflation status of the inflatable balloon system. Hence with the device according to the invention the actual inflation status of the inflated balloon system can be determined, providing accurate information about the operational conditions of the device during radiation treatments being performed in an animal body. Any malfunction can be easily detected thereby obviating the risk of any misadministration of a radiation dose to the patient.
