Abstract
The present invention is an apparatus for detecting ionizing radiation, having: a waveguide having a first end and a second end, the waveguide formed of a scintillator material wherein the therapeutic ionizing radiation isotropically generates scintillation light signals within the waveguide. This apparatus provides a measure of radiation dose. The apparatus may be modified to permit making a measure of location of radiation dose. Specifically, the scintillation material is segmented into a plurality of segments; and a connecting cable for each of the plurality of segments is used for conducting scintillation signals to a scintillation detector.
Claims13
An apparatus for detecting a therapeutic dose of ionizing radiation, comprising:
- a). a first waveguide having a first end and a second end, said waveguide being formed of a scintillator material whereby ionizing radiation isotropically generates scintillation light signals within said waveguide;
- b). a first optical cable attached to said second end of said first waveguide;
- and
- c). an optical interface at the contact between said second end of said first waveguide and said optical cable, whereby the numerical aperture of said second end of said first waveguide is properly matched with the numerical aperture of said first end of said optical cable at said interface, whereby optical efficiency is maximized, as measured along the optical axis.
