[高血压医学论文] 关键词: 乳腺癌 根治术 放射治疗 摘要: 乳腺癌根治术后病人CT图像送入三维治疗计划系统,观察6 MV X线切线照射及电子线垂直照射胸壁时的剂量分布。包括内乳淋巴结和不包括内乳淋巴结的6 MV X线切线照射无需楔形板;单纯电子线垂直照射,即使是6 MeV低能电子线,肺组织受照亦相当严重;6 MeV电子线配合皮肤表面填0.5 cm厚组织等效物,肺组织受照较小,皮肤剂量提高,但内乳淋巴结与其表面皮肤剂量不能两者兼顾;9 MeV电子线配合皮肤表面填不等厚度组织等效物,可使得90%等效剂量包括皮肤、胸壁和内乳淋巴结而肺组织受照很少;对皮肤和内乳淋巴结均需高量照射者,电子线配合皮肤表面填组织等效物垂直照射较X线切线照射有明显优势。
Chest wall radiotherapy technique and dose distribution for patients of breast cancer after radical mastectomy
Abstract Sending the CT images of the patients of breast cancer after radical mastectomy to CADPLAN 3D TPS, studying the dose distribution of 6 MV X-ray tangential irradiation and different energy electron ray perpendicular irradiation to chest wall. Some results were presented. Including or not including the intramammary lymph. It is not necessary for 6 MV X beam tangential irradiation to chest wall of the p……
