I have a number of DICOM files (series) from the last CT Scan of my brain.
The import is running well:
im = Import["…\IM000001.dic", {"DICOM", "Image"}];
I have chosen this command line because it keeps the MetaInformation in the image. The MetaInformation contains information like,
SliceThickness
SpacingBetweenSlices
SliceLocation
I assume this information is necessary to build a proper Image3D of my brain. But it seems to me that Mathematica does not make use of it. The image below contains 25 slices / images.
But the outcome is a rather flat representation:
A series of DICOM files is typically accompanied by a DICOMDIR file. If this is the case for you, the recommended way to import a 3D image would be:
Import["path/to/DICOMDIR", "Image3D"]
and it will automatically use the meta information to choose proper thickness of slices.
If you only have a series of DICOM files, import all of them to a list of images, as you have already done, extract the values of "PixelSpacing" and "SliceThickness" and pass these values as the BoxRatios option to the Image3D constructor.
Perhaps it would be wise to add a note in the documentation for DICOMDIR that this is a file. Less smart people like me are probably searching for a directory with this name. Of course, professionals will know it.
