Abstract: 삽입 손실에 있어서 향상된 성능을 제공하는, 광섬유 로터리 조인트(20)에 사용되는 광섬유 시준기들이 개시된다. 본 발명의 광섬유 시준기의 한 실시예는 4분의 1 미만 피치를 갖는 굴절율 분포 로드 렌즈(61)를 구비한다. 삽입 손실에 있어서의 향상은 피치가 감소함에 따른 실효 초점 거리의 증가와 그에 따른 연장된 작동 거리에 기인한다. 실효 초점 거리의 증가는, 더 전통적인 4분의 1 피치 굴절율 분포 로드 렌즈의 후방 초점 거리가 0인 것과 비교할 때, 렌즈의 후방 초점 거리의 증가를 동반한다. 이러한 후방 초점 거리의 증가는 광섬유(68)가 부착되는 원통형 유리 이격체(64)에 의하여 채워질 수 있는데, 이는 통상적인 4분의 1 피치 굴절율 분포 로드 렌즈 시준기에 매우 유사한 형태를 가진 시준기를 얻을 수 있도록 한다. 증가된 후방 초점 거리는 또한 직각 프리즘(71)에 의해서도 채워질 수 있는데, 이때 광섬유는 렌즈의 광학축에 90˚로 정렬되도록 직각 프리즘에 부착되고, 원하는 섬유 진입 방향이 로터리 조인트의 회전축에 수직인 팬케이크 스타일 하이브리드 슬립 링들의 응용사례들에 유용하게 된다.

Abstract: The present invention relates to a technique for absorbing I-125 into the support for cancer treatment and a method for manufacturing the I-125 seed using the same technique. In the method for manufacturing iodine according to the present invention, a mediator in which phosphate-based (PO4-), oxalate-based (C2O42-), or arsenate-based (AsO43-) anion is introduced is used so that the effect of iodine (I-125) substitution is three to five times higher than the existing mediator in which chloride anion (Cl-) is introduced. Due to the effect, the amount of radioactivity in iodine seed production is controllable and the iodine seed is able to be produced in a short time. Also the effect has an advantage in environmental aspects since residual radioactive iodine is reduced as a result of an excellent absorption so that the radioactive iodine (I-125) waste is reduced.
