PyDicom Encapsulated Files

[Neuroforge]

Description

Hello,

I wish to replicate the functionality of dcmtk's pdf2dcm tool. Are there samples or tests showing how to make an encapsulated file with Pydicom?

I'm not aware of any examples or tests but it should just be a matter of following the IOD for Encapsulated PDF Storage, most notably by including elements from the Encapulsated Document Series and Encapsulated Document modules (plus of course the other mandatory modules).

Hi Neuroforge,
I had a similar usecase recently where I wanted to convert pdf to encapsulated dicom. It's possible in pydicom by updating 'EncapsulatedDocument' and 'MIMETypeOfEncapsulatedDocument' tag.

Attaching
pdf2dicom.zip
the sample code where I create a new encapsulated document from a pdf file:

Update:

Created a sample code in case people need an example of usage:

@Neuroforge, were you able to work with the example given? Perhaps this issue can be closed and people can find this by search engines?

Hello,

I used a similar approach to @rohithkumar31. Save the file to a temp file, convert to dicom and the uploaded to our PACS server.

Please feel free to close the issue.

I am currently in the process of creating a python package to do this as well as the possibility to convert pdf to dicom rgb format maybe you can take a look at the project too.

What worked for me is the "dcm2pdf" command (https://support.dcmtk.org/docs/dcm2pdf.html / https://command-not-found.com/dcm2pdf).

In python, you can execute the command os.system("dcm2pdf "dicom_path" "pdf_saving_path").

After that, you will be able to extract the text using "pdfplumber" :

        with pdfplumber.open(r"path/to/pdf") as pdf:
            first_page = pdf.pages[0] # if many pages present implement a loop
            print(first_page.extract_text(x_tolerance=1))
