Claim 8:
9. A urinary catheter, the urinary catheter comprising: an afterloader catheter operable to carry a radiation source; a plurality of scintillators embedded into walls of the urinary catheter; and a plurality of optical fibers embedded into the walls of the urinary catheter, wherein: each scintillator is configured to produce light in a presence of radiation emitted from the radiation source, wherein the radiation source is moving, a level of the light produced by each scintillator is proportional to a level of the radiation incident to each scintillator, each optical fiber of the plurality of optical fibers is operably coupled to a scintillator of the plurality of scintillators, each optical fiber of the plurality of optical fibers is operably coupled to a light detection unit of a plurality of light detection units, each light detection unit is configured to produce an electrical signal in a presence of the light from one scintillator of the plurality of scintillators, a level of the electrical signal produced by each light detection unit is proportional to the light incident to each light detection unit a location of the radiation source is determined according to the plurality of electrical signals from the plurality of light detection units, wherein each of the plurality of electrical signals corresponds to a different scintillator of the plurality of scintillators, the urinary catheter comprises a balloon for expanding the urinary catheter according to a tumor location wherein the plurality of scintillators and the plurality of optical fibers are spread out when the balloon is expanded, and a velocity of the radiation source is determined according to the plurality of electrical signals from the plurality of light detection units, wherein the velocity of the radiation source is different than a velocity of the radiation emitted from the radiation source.
