摘要目的使用基于深度学习的AccuContour软件自动勾画胸腹部肿瘤患者正常胃和胸腔胃结构，对勾画效果进行评估和比较。方法选取36例胸腹部肿瘤患者，分为2组，其中18例正常胃患者为A组，其余18例食管癌术后胸腔胃患者为B组。使用AccuContour软件在患者的定位CT图像上自动勾画胃结构，对自动勾画和手工勾画的体积差异、位置差异、形状一致性进行统计分析，对2种胃结构的自动勾画效果进行比较。结果 A组患者自动和手工2种勾画方式的体积差异△V%为（-1.82 ±9.65）%，总位置差异ΔL为（0.51 ±0.37） cm，Dice相似性系数（Dice similarity coefficient，DSC）为0.89 ±0.04。对A组和B组数据进行秩和检验比较，△V%、ΔL和DSC值均有统计学差异（P < 0.05）。结论本研究所用版本的AccuContour软件，对于大于一定体积的正常胃结构有较好的自动勾画效果，而对食管癌术后胸腔胃结构不能进行有效自动勾画。
