| 摘 要： | 目的 通过仿真人体模型实验,针对现在所使用的腹部扫描条件,对患者的受照情况进行全面了解。方法 选择常规扫描参数和低剂量扫描参数,利用仿真人体模型,在相应体表位置和预定孔中插入剂量计,测量体表剂量和器官或组织的吸收剂量,并计算有效剂量。结果 常规剂量组和低剂量组的器官或组织的受照剂量范围分别为0.014~96.7 mGy,0.00148~5.56 mGy,有效剂量结果分别为14.5 mSv和1.52 mSv。结论 合理减少CT检查所致受检者剂量,需要建立科学实用的放射诊断的医疗照射参考(指导)水平。

| Abstract: | Objective The study investgated the patient doses in current abdominal CT conditions,used the phantom. Methods The phantom experiment was carried in routine mode or low dose mode. TLDs was placed on the surface and target hole of phantom Measures skin dose and organ or tissue absorbed dose and effective dose. Results The dose range of the conventional is 0.148 mGy~96.7 mGy orThe dose range of the low dose group is 0.012 mGy~5.56 mGy, and the effective dose was 14.5 mSv and 1.52 mSv. Conclusion The logical ramethod reduced the patient doses in CT examination, is on establishing a scientific、applied medical reference (guidance) level. |
