用Weasis查看器使用伪彩色软拷贝表示状态
用Weasis查看器使用伪彩色软拷贝表示状态
提问于 2022-06-02 14:34:58
我计划使用伪彩色软拷贝表示状态(PCSPS)将像素值从灰度空间映射到rgb空间。我不希望将原始dicom文件中的光度解释设置为“调色板颜色”(它是MONOCHROME2)，并添加颜色lut以避免编辑/复制原始文件(顺便说一下，上面的方法适用于获取假彩色图像)
我创建了一个表示文件(*.pre)，其中包含以下字段，其中引用SOP实例UID引用我的dicom文件。当我将表示文件加载到weasis中时，我可以看到更改的Modality和VOI的效果，但是颜色调色板lut不起作用，图像仍然是灰度图像。

到目前为止，weasis不支持伪彩色软拷贝表示状态。预计它将在6月底的下一个版本中添加参考员额。
