Abstract
The developed fiber-optic twin sensor allows in-vivo dose measurement in the tissue of the patient's body. It consists of two radiation-sens itive fibers. The radiation-induced attenuations of these fibers are u sed to determine the dose absorbed in tissue. The two signals have a l inear dose response, but they depend differently on the energy of the ionizing radiation. Evaluation of the two sensor signals permits a nea rly tissue-equivalent dose indication.
