文摘为了在医学图像中提高胰腺计算机断层成像(computed tomography, CT)自动分割的准确率,针对传统分割方法存在受噪声影响大、过分割、欠分割等问题,以及胰腺周围的重要结构组织关系紧密且多变、边缘界限不易确定等特点,提出了一种基于全局特征U-net(U-net with global features, GF U-net)的胰腺图像分割方法。该方法比基于传统深度卷积神经的U-net网络能够提取出更精确的形状、纹理信息,将胰腺图像区域的毛刺边缘进行平滑化,能够更好地把握胰腺的全局特征。通过对82个由美国国立卫生研究院(national institutes of health, NIH)公开的胰腺CT数据进行四折交叉验证,得到Dice相似系数(Dice similariy coefficient, DSC)的均值为87.13%±3.76%,比传统的U-net网络增长了7.43%。提出的方法不仅拥有更高的准确率,而且生成胰腺的形状边缘更加契合生物学上的胰腺形状,更容易应用在临床医学中。
