ITK 写入图像错误

Question

我对Pyscience 中描述的图像进行降噪，如下所示：

import SimpleITK as sitk

image=sitk.ReadImage("myimage.dcm")
imgSmooth = sitk.CurvatureFlow(image1=image,
                                timeStep=0.00125,
                                numberOfIterations=100)

我正在尝试将其保存为 dicom 文件：

sitk.WriteImage(imgSmooth, 'denoised.dcm')

但我有以下错误：

RuntimeError: Exception thrown in SimpleITK WriteImage:     ..\..\..\..\..\ITK\Modules\IO\GDCM\src\itkGDCMImageIO.cxx:1035:
itk::ERROR: GDCMImageIO(000000000F268380): A Floating point buffer was   passed but the stored pixel type was not specified.This is currently not supported 

我一般不能使用 SimpleITK 保存为 dicom 文件？如何将降噪后的图像保存为 dicom 文件？

Answer 1

我认为您需要将 float 转换为 int（或 uint）。

castFilter = sitk.CastImageFilter()
castFilter.SetOutputPixelType(sitk.sitkInt16)

# Convert floating type image (imgSmooth) to int type (imgFiltered)
imgFiltered = castFilter.Execute(imgSmooth)

sitk.WriteImage(imgFiltered, 'denoised.dcm')
