Fiber Optic Microbeam for Treating Brain Tumors
February 20, 2018 | Terry Sharrer
Microbeam radiation therapy has been used for about 20 years to treat brain tumors. In MRT, a collimator narrows a beam of x-ray particles, allowing higher doses upon narrow tumor spaces. The higher dosage, however, increases the need for measuring the amount of radiation the tissue receives. To advance this measurement, researchers at Wollongong University in Australia have created a fiber-optic scintillator that registers the dosage. “The preclinical trials of MRT have shown that normal tissue can tolerate peak doses 100 times greater than the doses used in conventional radiotherapy.” MORE
