| 中文摘要: |
| 目的 探讨中国头颈部体模的解剖结构,制作工艺和材料的合理性,以及实际应用的研究。方法 以中国”成都头颈部剂量体模“与美国RSD头部体模在解剖参数进行对比并与活体脑、软组织和头颅骨各部的CT值、质量密度、有效原子序数理论值、实测值等做比较并进行CT扫描辐射剂量分布的测定。结果 中外体模解剖参数比较差异有显着性,作为活体组织的替代材料其等效误差在5%,达到国际标准A级。结论 中国头颈部体模能够代替活体应用于放射诊断治疗和防护的研究。 |

| Objective To study the dissection structure of a Chinese head and neck phantom and to evaluate the reliability of technology and materials of phantom manufacture as well as its clinical appliability. Methods The phantom was compared with the head phantom of RSD, USA, and Chinese “Chengdu head dosimetric phantom” and with CT values, mass density, theoretical and experimental effective atomic numbers of in vivo human soft tissues, brain and parts of the skull.CT scan dose distribution was also mreasured.Results The experimental results showed that there were remarkable differences between the dissection parameters of the Chinese phantom and the American one.The equivalent error as the substitute for human head and neck is under 5%, which reaches Class A of the international standard. Conclusions The Chinese head and neck phantom can be used as a substitute for the living body radiological diagnosis, radiological treatment and protection. |
