Objective Using three dimensional treatment planning system,to assess the dosimetric of different radiation therapy planning and to obtain a better technique in the treatment of non- small cell lung cancer.

本篇&非小细胞肺癌不同放射治疗计划的剂量学研究&文章由免费论文网免费为您提供！

The bone dosimetric values are influenced by the parameters of skeleton mass.

鉴于骨骼组织不同部位的辐射敏感性存在差异［2］，特别是已确认骨髓的造血干细胞和衬在骨表面上的成骨细胞是骨骼中致癌危险的靶细胞，因而ICRP30号出版物［3］详细介绍了估算骨骼靶器官的吸收剂量的骨剂量学模型，使骨剂量的计算趋向精确。1995年，ICRP又专门编著了用于辐射防护的骨骼解剖和生理参数的70号出版

Monte Carlo simulation is one of effective ways to get this kind of dosimetric parameters. In this paper, the absorbed doses at the central axis in different phantoms with inhomogeneity media and finite sizes for small field size beams were simulated with Monte Carlo code system EGSnrc, respectively.

本文利用蒙特卡罗方法模拟计算了临床上常用的点源光子束在有限宽非均匀模体中的沉积能量，研究了不同射野条件下中心轴上的剂量分布，并用剂量扰动因子定量分析了剂量增强或减弱效应的强度。

Both IMRT and conventional radiotherapy were planned for every patient. After comparing the radiation dose and volume to the heart and lung, and other dosimetric parameters, we then decided which technique to use for individual patient.

我们针对每个案例同时使用强度调控放射治疗及传统放射治疗做电脑计画，在比较心脏及肺脏的放射剂量、照射体积，和其他剂量分析参数后，再决定选用哪一套治疗计画做实际的临床治疗。

Dosimetric study on dose perturbation in inhomogeneities for small beamlets has been a very intractable question in the field of tumor radiation physics at all times. The measured uncertainty and the complexity of the media, such as bone, lung, cavity and their boundaries, lead to the difficulty of this kind of problems.

小射野在非均匀异质组织中的剂量特性研究一直是肿瘤放射物理领域中一个难点问题，其原因在于测量的不确定性和体中骨头、肺、气腔中以及它们和组织交界处的复杂性。

The transmitted MPPSfiles contain basic dosimetric information butmany Radiological Information Systems stilldo not accept these files.

传输的无阻塞文件包含的基本资料，但剂量学许多放射信息系统仍不接受这些文件。

The dosimetric characteristics in TSET were much different from the general single beam. The measurement before the treatment is necessary.

全身电子束照射条件下电子束剂量特性与常规条件下特性有很大不同，必须通过实际测量来为临床照射提供依据。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
