Abstract

A radiation dosimeter for measuring radiation dose within a region includes a structure having a scintillating material that emits light when exposed to radiation. Deformable radio-luminescent elements are located within the structure and configured to generate optical energy in response to irradiation.

First claim

The invention claimed is:

1. A system for measuring radiation dose, comprising:
a radiation dosimeter;
a deforming device having a first portion and a second portion sized to receive the radiation dosimeter therebetween, at least one of the first and second portions being movable relative to the other portion to deform the radiation dosimeter;
wherein the radiation dosimeter comprises:
a phantom; and
one or more deformable radio-luminescent elements located within the phantom and configured to generate light as a direct response to irradiation, wherein the radio-luminescent elements have different optical emission spectra.

2. The system of claim 1 , wherein the phantom is deformable.

3. The system of claim 1 , wherein at least one radio-luminescent element is deformable.

4. The system of claim 1 , wherein the radio-luminescent elements are contiguous.

5. The system of claim 1 , wherein the one or more radio-luminescent elements comprise water and/or tissue equivalent materials.

6. A system for measuring radiation dose, comprising:
a radiation dosimeter;
a deforming device having a first portion and a second portion sized to receive the radiation dosimeter therebetween, at least one of the first and second portions being movable relative to the other portion to deform the radiation dosimeter;
wherein the radiation dosimeter comprises:
a structure comprising a scintillating material, wherein the scintillating material emits light when exposed to radiation; and
one or more radio-luminescent elements located within the structure and configured to generate light as a direct response to irradiation.

7. The system of claim 6 , wherein the structure is deformable.

8. The system of claim 6 , wherein at least one radio-luminescent element is deformable.

9. The system of claim 6 , wherein the radio-luminescent elements are contiguous.

10. The system of claim 6 , wherein the radio-luminescent elements have different optical emission spectra.

11. The system of claim 6 , wherein the one or more radio-luminescent elements comprise water and/or tissue equivalent materials.

12. The system of claim 6 , wherein the structure or the radio-luminescent elements are configured to take a shape of one of: an organ and an anatomical region.

13. The system of claim 12 , wherein the anatomical region comprises any one of: a thorax, a neck, a head, and a pelvis.

14. A radiation system for real-time measurements of a radiation dose within a region, comprising:
a radiation dosimeter that comprises a structure and one or more radio-luminescent elements, wherein the structure comprises a scintillating material, the scintillating material emits light when exposed to radiation and the one or more radio-luminescent elements are located within the structure and configured to generate light as a direct response to irradiation;
a deforming device having a first portion and a second portion sized to receive the radiation dosimeter therebetween, at least one of the first and second portions being movable relative to the other portion to deform the radiation dosimeter; and
a processor configured to receive radiation data from the radiation dosimeter.

15. The radiation system of claim 14 , wherein the radiation dosimeter comprises a deformable material.

16. The radiation system of claim 14 further comprising a radiation source for irradiating the radiation dosimeter.

17. The radiation system of claim 5 , wherein the radiation data are recorded while the radiation dosimeter is being deformed.

18. A method for measuring a radiation dose, comprising:
positioning a radiation dosimeter for real-time measurements of the radiation dose within a deforming device having a first portion and a second portion sized to receive the radiation dosimeter therebetween, at least one of the first and second portions being movable relative to the other portion to deform the radiation dosimeter,
wherein the radiation dosimeter comprises a structure and one or more radio-luminescent elements, wherein the structure comprises a scintillating material, the scintillating material emits light when exposed to radiation and the one or more radio-luminescent elements are located within the structure and configured to generate light as a direct response to irradiation;

irradiating the radiation dosimeter;
deforming the radiation dosimeter by actuating the at least one of the first and second portions of the deforming device; and
receiving radiation data from the radiation dosimeter.
