[MINC-users] Dicom to Minc converter for Phillips ?

[Hyun-Pil Kim]

I've tested the -ignore_positions option and it complained about reading
slice position but somehow it worked.

Besides, I ran tests using Analyze. Import/export module of Analyze told
something about SliceLocation order. Guessing by the output images, there
might be a trouble with processing interleaved slice orders. I'll send you
the captured images using the mni upload gateway. I am sure that you can
come with a good way of processing interleaved slices.

Thanks,
Phil.

|It seems that your dcm files have the ImageOrientationPatient
|(0x20,0x37) field filled in, but not the ImagePositionPatient
|(0x20,0x32).  dicom3_to_minc uses both these fields in order to
|determine the slice position in the out of slice dimension...  There
|is an option (-ignore_positions) in dicom3_to_minc which lets you tell
|it to use the image number instead of the slice position, which I had
|added specifically to handle cases where slice position could not be
|calculated properly, with the caveat that your step in the out of
|slice dimension will be 1mm (assuming consecutive image numbers)
|instead of whatever it should really be, and the start coordinate in
|that dimension will be wrong.  However, a simple header hack could fix
|that.
|
|There also seems to be a field SliceLocation (0x20,0x1041) which your
|data contains, but the values are not unique across the range of
|slices, so it would be difficult to use that, as dicom3_to_minc would
|complain of duplicate slices at a given position, and proceed to
|ignore all but one slice at each position.
|
|I'm open to suggestions if you can think of a sensible way to handle
|this kind of data...

|Cheers,
|Jon
