摘要
全身照射(TBI)是放射治疗的一种治疗方式。它可用于移植患者的免疫抑制或转移方案。在这项研究中，使用充满热致发光剂量计(tld)的拟人Alderson-Rando幻体进行TBI，并在两个不同的设置中使用Elekta线性加速器的6 MV光子束照射，一个在密歇根州 o Francisco医院，第二个在密歇根州拉夫拉斯的Santa Casa医院。估计、分析左、右肺的剂量分布，并与文献结果进行比较。结果表明，双场辐照的剂量均匀性较好。
Assessment of dose heterogeneity in TBI using the thorax of the anthropomorphic Alderson-Rando phantom and TLDs in two different setups
Total body irradiation (TBI) is a treatment modality of radiotherapy. It can be used for immunosuppression of transplanted patients or for metastatic protocols. In this study, TBI was performed using the anthropomorphic Alderson-Rando phantom filled with thermoluminescent dosimeters (TLDs) and irradiated with a 6 MV photon beam from the Elekta linear accelerator in two different setups, one at the hospital São Francisco, BH, MG and second at the hospital Santa Casa in Lavras, MG. The dose distribution in the left and right lungs was estimated, analyzed, and compared with results from the literature. Our results showed that dose homogeneity is more adequate with dual-field irradiation.
