CT Single file multi frame
Hi all,
i'm in dicom and i need help if is possible.
I have a sequence of axial from the same exam and i want to create a
single file with all this axial.
So i created a dicom file with media storage SOP class UID of CT
(1.2.840.100008.5.1.4.1.1.2), i created the tag
Number of frames 0028,0008 with the number of my axial and the i
created the image group with all the axial the first one is the upper
of my series and the last one is the lower. Obviously i created all
the tag of CT sop class including Slice thickness 0018,0050.
I'd like to know if this file is correct for one single multi-frame
image.
Thanks in advance

Hi MM,
I think you meant to say: 1.2.840.10008.5.1.4.1.1.2 (CT Image
Storage), if so then no you cannot have multiple frames. Instead you
should consider the new CT object: 1.2.840.10008.5.1.4.1.1.2.1
(Enhanced CT Image Storage). You should check PS 3.3- 2008 for the
list of attributes required for this class, since it greatly differ
from the previous class.

Re: CT Single file multi frame
Hi Mathieu,
thanks a lot for your prompt answer, but i have another question back:
yes i meant 1.2.840.10008.5.1.4.1.1.2 (CT Image Storage). Now i create
one dicom files for all my axial (i.e. 10 images = ten files) and i
want to accorpate in only one file, with the same header contains
typically patient information and information about the image
capturing modality (typically of CT Image Storage) and then create
only one image (tag 7fe0, 0010) containig all the axials. This way
make me earm a lot of time (if is Dicom correct). I saw that some
viewer can read all the axials from my one single multi frame image
so how could be possible if my single file is not dicom correct that
the viewer can read it?
Thanks in advance for your help.

Re: CT Single file multi frame
You cannot do what you want to do with 1.2.840.10008.5.1.4.1.1.2.
As Mathieu stated quite clearly, for 1.2.840.10008.5.1.4.1.1.2,
only 1 frame (1 slice) is allowed.
So the files that you are describing are illegal, without any
question, regardless of whether or not some viewers happen not
to care and display them anyway.
If you want multiple CT frames in a single instance (file) then
you have to use Enhanced CT (1.2.840.10008.5.1.4.1.1.2.1).
