- Analyze the target volume before you install large applications and defragment the volume if necessary. 在某个盘上安装体积较大的程序前,先进行磁盘碎片整理。
- Biological effective dose(BED) was increased for GTV.but the BED for clinical target volume(CTV) was adequately reduced. 肿瘤组织有效生物剂量 (BED)在大体靶区体积 (GTV)剂量有所提高而临床靶区体积 (CTV)剂量有所降低 ;
- Then, the gross tumor volume (GTV),clinical target volume (CTV) and planned target volume (PTV) were delineated on every section of the CT scans. 然后在所有CT层面逐层勾画出鼻咽肿瘤的大体肿瘤体积 (GTV)、临床靶体积 (CTV)和计划靶体积 (PTV)。
- Results The planning target volume was enclosed by 95%isodose line while the dose to the organ at risk were kept below TD5/5 significantly. 结果 95%25等剂量线包绕计划靶区,危及器官的受量大大低于其耐受剂量(TD5/5)。
