Abstract
The present invention relates to a fiber-optic sensor system for measuring the relative dose of a therapeutic proton beam by measuring Cerenkov radiation and a method of measuring using the same, and more particularly to a fiber-optic sensor system for precisely and economically measuring a proton beam by measuring the Cerenkov radiation generated from a fiber-optic sensor and a method of measuring using the same. The present invention comprises a proton beam source, a fiber-optic sensor for measuring the Bragg peak of the proton beam and SOBP, an optical detector for measuring the Cerenkov radiation, and a pair of optical fibers connecting the fiber-optic sensor and the optical detector, wherein the fiber-optic sensor being irradiated with a proton beam, the Cerenkov radiation generated in the optical fibers themselves is delivered through the optical detector to an amplifier system, and the resulting signal is transferred to a computer.
