腹腔内恶性肿瘤一般采用常规的固定单射野和成角度斜射野的全腹照射方法进行治疗,但由于病人局部脏器耐受性的限制以及机体对放射治疗的反应直接影响了治疗效果,目前国外则采用“移动条”全腹照射的方法对此类病人进行治疗,即通过多射野重复连续多次照射,使得病人在可耐受的范围内,其腹部的局部组织在短期内获得了较高的剂量,以此来达到控制肿瘤的发展。由于这种方法采用了多射野多次腹背交叉照射,故很难用计算的方法给出准确的结果。国外文献上报导了一些这方面的实验结果,但由于所 Intraperitoneal malignant tumors are usually treated with conventional fixed single-field and full-abdominal irradiation with angled oblique fields. However, due to limitations of local organ tolerance and the body’s response to radiation therapy, the treatment effect is currently Abroad is the use of “moving strip” full abdominal irradiation of such patients for treatment, that is, repeated radiation through multiple repeated repeated exposure, making the patient within the tolerable range, the abdominal tissue obtained in the short term Higher doses, in order to achieve the control of tumor development. Because this method uses multiple shots multiple cross-abdomen cross-irradiation, it is difficult to calculate the method to give accurate results. Foreign literature reported some experimental results in this area, but due to
