  • Patent number: 9662408
    Abstract: The present invention relates to a fiducial marker comprising barium sulfate (BaSO4), 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.
