ABSTRACT
Objective To develop a simulation phantom for clinical detection of radiation intensity at the organs or tissue vulnerable to X-ray. Methods The organs or tissue vulnerable to X-ray radiation were explored to determine the region of interest of the radiation to the phantom. A mathematical model was established, and the technical characteristics of the equivalent materials of different tissues were studied. The existing ion chamber probes were compared on the technical performances, and the probe was selected with considerations on comprehensive factors. The phantom was gifted with two sizes of adult and child and designed based on the positions of sensitive organs. Practical trials were carried out to test the performances of the phantom. Results The phantom could be used to measure the radiation dose which was equivalent to the value of multiple human organs, and the desired requirements were fulfilled. Conclusion The phantom gains advantages in simulation fidelity, withdrawal of the probe and etc, and thus is worthy promoting practically.
