A device for measuring a radiation dose according to the present invention includes a radiation exposure unit which exposes radiation, a frame unit which supports the radiation exposure unit, a measurement housing unit which is mounted on the frame unit, a scintillation unit which is mounted on the measurement housing unit and emits light due to the radiation exposed by the radiation exposure unit, an image capturing unit which captures an image of the scintillation unit, and a dose measuring unit which measures, on the basis of the captured image obtained by the image capturing unit, a dose of radiation to which the scintillation unit is exposed.

Radiation dose measurement device and measurement method

The present invention relates to a fiducial marker comprising barium sulfate (BaSO), a solvent, and a polyethylene glycol-poly(aminourethaneurea) multi-block copolymer, as active ingredients. The fiducial marker of the present invention has an effect of significantly remedying disadvantages of image distortion and dose distortion, which are involved in the gold inner marker used in the conventional art. The fiducial marker of the present invention has very limited in vivo mobility, and thus the fiducial marker is maintained at the position at which it has been initially injected. Since the fiducial marker of the present invention is maintained in a sol or liquid state before in vivo injection, and transited into a gel or solid phase after in vivo injection, the injectability of the fiducial marker by an injector syringe is favorable, and the state of the fiducial marker can be controlled into a phase suitable to each site of the therapeutic target.
