volume dose

Local control rate of nasopharyngeal cancer was positively correlated with the target volume dose.

鼻咽癌的局部控制率与靶体积的照射剂量呈正相关。

Results 1. The dose distribution of the improved plan could meet the requirements for the target volume.

结果（1）改进方案可满足鼻咽和颈部计划靶体积的剂量要求。

The received dosage by the parotid was analyzed by dose-volume histogram ( DVH).

并利用DVH图对腮腺组织进行受量分析。

The fractional dose and volume of GTV are independent prognostic factors for the overall survival.

分次剂量和GTV体积为影响患者生存时间的独立预后因素。

Methods From January 2001 to March 2002,24 patients with locally recurrent NPC were treated by 3DCRT with the dose of 28 Gy/ 7f/ 15 days in the planning target volume, following routine radiotherapy of 40Gy/ 20f/ 4 weeks.

方法2001年1月～2002年3月，采用常规放疗结合三维适形放疗治疗局部复发鼻咽癌24例，常规外照射40Gy/20次/4周后进行适形放疗，治疗剂量为28Gy/7次/15d。

Methods The mouse myelosuppression model was made by a single abdominal injection of high dose CTX. The effect of SXS on the CFU GM number and the volume of hematopoietic tissue ( VOL) of normal and model mice were observed.

方法：采用大剂量CTX一次性腹腔注射法建立小鼠骨髓抑制模型，观察生血散对正常及模型小鼠骨髓CFU-GM形成率和骨髓造血组织容量的影响。
