Performance evaluation of axxent electronic brachytherapy system model 110

Traditional brachytherapy refers to the placement of radioactive sources on or inside the tumor. Electronic brachytherapy (EB) is new form of radiotherapy which utilizes miniature X-ray source instead of radioactive source to deliver desired doses to tumor. The advantages of EB include low dose to surrounding organs, simple emergency handling procedures, lesser shielding requirements, no leakage radiation in off state and no radioactive waste. Purpose of this paper is to discuss performance evaluation of Axxent EB system model 110 with respect to conformance with manufacturer's specifications and existing QA protocol of brachytherapy, as applicable. This unit is intended to deliver intracavitary, surface radiation and Intra Operative Radiation Therapy (IORT) and not suitable for interstitial application due to larger source dimension
