Phantom for verification of accuracy of HDR brachytherapy planning and Phantom device having the phantom

摘要

The present invention relates to a phantom device with a high dose rate brachytherapy plan accuracy evaluation phantom and the phantom for. ; And the applicator is inserted into the body to close the phantom irradiated to the tumor in the cervix and for receiving the radiation emitting substance therein; And the cube shape of the applicator holder for fixing the applicator; And a lower block that supports the applicator holder; And an upper block that is an interview installed on an upper surface of the applicator and the lower block; The lower block and is configured to include the first and second block sides that are divided by a plane perpendicular to the applicator holder and the upper block doedoe installation interview to the vertical side with the upper surface and side surface of the applicator holder. ; The Phantom and Phantom apparatus of the present invention made, as are low because the configuration as simple acrylic assembly and simple to individuals and small to medium-sized even make and use as many hospitals, and in particular the dose calculation algorithm and a position calculation algorithm of the treatment planning computer it can be easily verified by the simple principle allows so much so easy to manage, prevent radiological accidents resulting from the neglect of quality control in advance.
