Objective To investigate the radiation absorbed dose, clonogenic cells survival fraction and TCP ( tumor control probability ) during tumor therapy with interstitial injection of Beta radionuclide in order to prognosticate the therapeutic efficiency. 目的:为了探讨肿瘤内注射90Y核素治疗疗效,对治疗中吸收剂量、细胞存活率的时空分布和肿瘤控制概率进行研究。
The contributions of photon radiation to absorbed dose in cells were ignored. 光子对细胞或细胞核的剂量贡献忽略不计。
Ionizing radiation exposure is measured as " absorbed dose " in gray ( Gy ). 电离辐射的暴露以戈瑞(Gy)“吸入的剂量”来衡量。
Correlated gene take part in the course of radiation regulating induce. Chose idea absorbed dose and adjust Bcl - 2 / BAX and add esophagus cancer radiosensitivity are important. 相关基因参与调控辐射诱导过程,选择合适吸收剂量调整Bcl-2/BAX比值,增加食道癌放射敏感性较为重要。
When irradiation response and dose are linear, total dose radiation and post-irradiation annealing at room temperature are determined for one random by choosing absorbed dose rate, and total dose effect at other absorbed dose rate can be predicted by using linear system theory. 研究结果表明,辐射响应与吸收剂量成线性关系时,在实验室选用任一特定剂量率进行总剂量辐射和辐照后室温退火,可以通过线性响应理论模拟其它剂量率辐射下的总剂量效应。
