Import & Export

  • Import["file.dcm"] imports a DICOM file, returning an Image object.
  • Import["file.dcm",elem] imports the specified element from a DICOM file.
  • The import format can be specified with Import["file","DICOM"] or Import["file",{"DICOM",elem,}].
  • Export["file.dcm",expr] exports graphics or any other expression as an image to a DICOM file.
  • When exporting Wolfram Language graphics or arbitrary expressions to DICOM, the resulting image has the same raster size as its displayed form.
  • Image objects are by default exported at their raster size.
  • Because DICOM is a raster image format, all fonts are rasterized on export.
