Tumor Radiotherapy embedded x-ray radiation dose detection fiber probe

Tumor Radiotherapy X-ray radiation dose detection of embedded fiber probe, a medical instrument technical field. In order to solve the conventional fluorescent signal coupling surface coating techniques into the fiber core a low proportion of poor sensitivity and large size of the probe, it is difficult for in vivo measurements of the radiation dose problem. A program: a fiber optic probe comprises an optical fiber core of the optical fiber polymer material, the polymer material of the optical fiber into the probe end to end with a portion micromachined micro-pores, micro X-ray fluorescence material embedded in the hole, the hole Miniature port sealed using sealant . Scheme Two: the optical fiber comprises a silica fiber probe, the probe end to end into a solid core portion of the fiber core silica optical fiber is welded capillary fiber material embedded in X-ray fluorescence capillary fiber, capillary fiber port sealed using a sealant. The present invention achieves real-time monitoring of in vivo X-ray radiation dose, radiation therapy to reduce side effects as possible while increasing the efficacy of, and having a nominal functionality tumor site.
