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 located in one or more optical fiber lumens that pass through the urinary catheter, wherein: the urinary catheter comprises an inflation lumen, in a deflated state, a diameter of the inflation lumen is smaller than a diameter of each of the one or more optical fiber lumens, each scintillator is configured to produce light in a presence of radiation from the radiation source, 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; and a location of the radiation source is determined according to the 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 near a tumor location wherein the plurality of scintillators and the plurality of optical fibers are spread out when the balloon is expanded.
