- Disposable radiochromic opticalfiber dosimeter probe
- *Abstract
-
The real-timeradiochromic dosimeter is an ultra-thin fiber-optic dosimetric point probe thatcan be implanted in a minimally-invasive way directly into tumors or peripheraltissue, or positioned on the skin to monitor and verify applied therapeuticdose in real-time. Specific applications include the various forms of HDR(high-dose rate) brachytherapy (ie. prostate, gyne, post-lumpectomy) andIntra-Operative.
Unique advantages of this dosimeter are its sub-millimeter size, truereal-time non-destructive read out capabilities, water equivalent compositionand magnetic resonance (MR)-compatibility. It is a passive dosimeter, resultingin improved overall signal to noise (SNR) achieved by adjusting the amount ofinterrogating light.
