Needles size device created to tumors, radiation dose track
Engineers at Purdue University are creating a wireless device designed to be injected into the tumor to tell doctors the precise dose of radiation received and locate the exact location of the tumor during treatment. Information to help more effectively kill tumors, said Babak Ziai, an associate professor in the School of Electrical and Computer Engineering and a researcher at Purdues Birck Center Nanotechnology. Ziai leads a team that has tested a prototype wireless implantable passive micro-dosimeter and said the device could be in trials in 2010.Because organs and tumors shift inside to tell the body during treatment, a new technology is needed for doctors in the exact dose of radiation received by a tumor, said Ziai. The prototype is enclosed in a glass capillary smallenough to be injected into the tumor with a syringe, said Ziai, who has a dual appointment at Purdue Weldon School of Biomedical Engineering. The search results are presented in a detailed document that in the June issue of IEEE Transactions on Biomedical Engineering.
