乳腺癌皮肤转移放疗需要大照射野与高剂量。作者拟检验在已放疗与未放疗过皮肤上的乳癌转移应用后装模型超分割放疗的疗效与后果。开发可应用于脉冲式后装机的皮肤模型。一排18个平行的导管缝合于两层泡沫橡胶平片状物之间,该层状物厚5mm,以提供与皮肤间保持一恒定距离,每导管间距10mm。可人为地制定皮肤照射野之形状,最大射野大小为17cm×23.5cm。应用一标称37GBq(GBq为
Breast cancer skin metastases requires large radiation fields and high doses. The authors intend to test the efficacy and consequences of hyperfractionated radiotherapy after the application of breast cancer metastasis on irradiated and untreated skin. Develop skin models that can be applied to pulsed rear loading machines. A row of 18 parallel catheters was sutured between two layers of foam rubber flat sheet, which was 5 mm thick to provide a constant distance from the skin, 10 mm per catheter spacing. Can artificially formulate the shape of the skin irradiation field, the maximum size of the field is 17cm × 23.5cm. Apply a nominal 37GBq (GBq is
