Claim Text:
1. A method for detecting a position of a proton or x-ray beam, the method comprising: receiving the proton or x-ray beam by a treatment balloon, where the treatment balloon includes a shaft and a balloon portion with an open end in communication with the shaft, the balloon portion effective to be at least partially filled with a fluid inside of the balloon portion, the treatment balloon including a Cernekov detector effective to generate a light wave in response to detecting charged particles moving faster than the speed of light in the fluid inside of the balloon portion, wherein the charged particles are generated when the proton or x-ray beam is incident upon an outside of the treatment balloon, and the light wave is generated by the Cernekov detector inside the balloon portion; receiving the light wave by a waveguide in the treatment balloon; detecting the light wave by a light detector in optical communication with the waveguide; and detecting the position of the proton or x-ray beam by a processor in communication with the light detector.
