PDF to Encapsulated DCM

Usage

from pdf2dcm import Pdf2EncapsDCM

converter = Pdf2EncapsDCM()
converted_dcm = converter.run(path_pdf='tests/test_data/test_file.pdf', path_template_dcm='tests/test_data/CT_small.dcm', suffix =".dcm")
print(converted_dcm)
# [ 'tests/test_data/test_file.dcm' ]

Parameters converter.run:

• path_pdf (str): path of the pdf that needs to be encapsulated
• path_template_dcm (str, optional): path to template for getting the repersonalisation of data.
• suffix (str, optional): suffix of the dicom files. Defaults to ".dcm".

Returns:

• List[Path]: list of path of the stored encapsulated dcm

PDF to RGB Secondary Capture DCM

Usage

from pdf2dcm import Pdf2RgbSC

converter = Pdf2RgbSC()
converted_dcm = converter.run(path_pdf='tests/test_data/test_file.pdf', path_template_dcm='tests/test_data/CT_small.dcm', suffix =".dcm")
print(converted_dcm)
# [ 'tests/test_data/test_file_0.dcm', 'tests/test_data/test_file_1.dcm' ]

Parameters converter.run:

• path_pdf (str): path of the pdf that needs to be converted
• path_template_dcm (str, optional): path to template for getting the repersonalisation of data.
• suffix (str, optional): suffix of the dicom files. Defaults to ".dcm".

Returns:

• List[Path]: list of paths of the stored secondary capture dcm

Notes

• The name of the output dicom is same as the name of the input pdf
• If no template is provided no repersonalisation takes place
• It is possible to produce dicoms without a suffix by simply passing suffix="" to the converter.run()

Repersonalisation

It is the process of copying over data regarding the identity of the encapsualted pdf from a template dicom. Currently, the fileds that are repersonalised are-

• PatientName
• PatientID
• PatientSex
• StudyInstanceUID
• SeriesInstanceUID
• SOPInstanceUID
