如何重叠两个标签以在ITK-snap中制作用于分割的掩模？
我正在用 ITK-snap 注释 CT 扫描切片（Nifti 格式）。一张切片在同一区域包含两个标签（蛛网膜下腔和实质内）。以下是原始带注释的图像链接：https://ibb.co/FJpyVZF 由于两个标签重叠，因此切片中的交叉区域应包含两个标签。但它显示它只包含最后绘制的标签。由于蛛网膜下腔区域是最后在实质内区域上绘制的，因此最终的分割图像仅显示其在相交区域中包含蛛网膜下腔。我正在附加带注释的切片 https://ibb.co/F3TrXtq 和分段切片 https://ibb.co/sRgdndY 来澄清我的观点。 如何使交叉区域包含两个标签？
I'm annotating CT scan slices(Nifti format) with ITK-snap. One slice contains two labels(Subarachnoid and Intraparenchymal) in the same area. Here is the original annotated image link: https://ibb.co/FJpyVZF
Since two labels are overlapping, the intersection area in the slice should contain both labels. But it shows it only contains the label which has been drawn last. Since the Subarachnoid area was drawn last over the Intraparenchymal area, the final segmented image only shows it contains Subarachnoid in the intersection region. I'm attaching the annotated slice https://ibb.co/F3TrXtq and segmented slice https://ibb.co/sRgdndY to clear my point.
What can I do to make the intersection area contain two labels?

ITK-SNAP 使用二进制标签图。该方法不允许标签重叠。您的选择是：
ITK-SNAP uses binary label maps. That approach does not allow label overlap. Your options are:
