Half-body radiotherapy to deliver doses up to 1000 rads in a single exposure evolved to meet a need in treating patients with advanced cancer. Large fields are required and a high radiation output. Treatments are well tolerated, although radiation sickness occurs in 80% of upper half and 33% of lower half-body treatments. Marrow depression is not a problem and the second half body can be treated when the peripheral blood count has returned to normal. Subjective improvement occurs in most patients and this group had a median survival of six months.
半身放疗单次照射剂量可达1000拉德，其发展是为了满足治疗晚期癌症患者的需求。需要大照射野和高辐射输出。治疗耐受性良好，尽管80%的上半身和33%的下半身治疗会出现辐射病。骨髓抑制不是问题，当外周血细胞计数恢复正常时可对另一半身体进行治疗。大多数患者有主观改善，该组患者的中位生存期为6个月。
