Manufacture of plastic scintillation dosimeters
View Patent ↗A radio-opaque plastic scintillator detector (PSD) for use in various medical applications and methods of making and using the PSD. The method requires coating a plastic scintillator fiber with a radio-opaque material; cutting the scintillator fiber; stripping the end of a plastic fiber optic fiber; cutting the naked end of a plastic fiber optic fiber; inserting a closely fitting guide tube over the naked end and inserting the cut scintillating fiber into the guide tube; coating the detector end of the cable with a light opaque polymer or jacket and adding a connector to the other end.

5. The device of claim 4 , wherein the plastic material is a polystyrene-based fiber with green or blue light emission.
6. The device of claim 1 , wherein at least a portion of the scintillator fiber is coated with a light opaque polymer.
7. The device of claim 6 , wherein the light opaque polymer is a heat shrink polymer.
8. The device of claim 7 , wherein the heat shrink polymer comprises a depth marker.
9. The device of claim 1 , wherein the scintillator fiber is optically coupled to the optical fiber.
10. The device of claim 9 , wherein the scintillator fiber is optically coupled to the optical fiber with an adhesive.
11. A device comprising:
a scintillator fiber and an optical fiber;
wherein at least a first section of the scintillator fiber is coated with a suspension comprising a radio-opaque material in a binder;

13. The device of claim 12 , wherein the scintillator fiber is optically coupled to the optical fiber.
14. The device of claim 13 , further comprising a guide tube coaxially placed over at least a portion of the scintillator fiber and at least a portion of the optical fiber.
15. A device comprising:
a scintillator fiber;
wherein at least a first section of the scintillator fiber is coated with a suspension comprising a radio-opaque material in a binder;
wherein at least a second section of the scintillator fiber is covered with a light opaque polymer.
16. The device of claim 15 , wherein the radio-opaque material is comprised of any of iodine, cobalt, gold, bismuth, barium, or tungsten.
17. The device of claim 15 , further comprising an optical fiber; and
wherein the scintillator fiber is optically coupled to the optical fiber.
18. The device of claim 17 , further comprising a guide tube coaxially placed over at least a portion of the scintillator fiber and at least a portion of the optical fiber.
19. The device of claim 15 , wherein the scintillator fiber is a plastic material.
