| Outline of Final Research Achievements |
Tungsten functional paper (TFP) has the features of both radiation shielding and paper, and also non-toxicity for human body. This study aimed the expanded adaption of the TFP to the medical field. We performed four experimental researches as follows, (1) Radiation shielding abilities in permanent prostate brachytherapy: The under garment made of the TFP has been developed and it reduced dose for care givers and family against the radiation from a patient who underwent the permanent prostate brachytherapy. (2) Radiation shielding for an operator in IVR: The TFP had enough shielding ability to reduce the exposed dose for the operator during IVR. (3) Application on the electron grid therapy: Grid irradiated field can be created by laying the TFP grid collimator on a patient’s body. (4) Chest wall protector in intraoperative electron therapy for breast cancer: Implementation of safely insert the TFP into a patient body by the small range incision due to the flexible of the TFP.
