研究采用β-粒子源进行内照射治疗时，放射源的不同分布状态对肿瘤的吸收剂量分布的影响，比较β-粒子源在肿瘤区域以点源状态分布和均匀状态分布状台下肿瘤的吸收放射剂量分布情况，得到β-粒子源内照射治疗肿瘤选用放射源分布状态的最佳方案，其结果对β-粒子源内照射治疗的临床应用具有指导意义。

Based on theβ-particle source for internal Radiation therapy,effects of absorbed dose distri-bution of radiation source for tumor radiation,We compare the absorbed dose rate of the tumor with two dif-ferent radioactive source distribution,the first is uniform distribution in tumor targeting;the second is point source distribution in the center of tumor with inj ect intratumorally,Finally get the best scheme ofβ-particle source internal radiation for cancer with radiation source distribution,results can guide the clinical...
