This repo shows how to convert whole slide image into multi-frame DICOM images. It depends on Openslides and Pydicom

Motivation

• Standardize WSI formatting and transferring throughout institutions.
• Enable more encapsulation options for massive data storage
• Potentially simplify patch/frame level accessibility of whole slide images

Here is an example showing the converted DICOM can be viewed in a DICOM viewer Orthanc.

Dependencies Installation

pip install pydicom openslide_python

You may also need to install OpenSlide library other than python interface.

Quick Start

Code is super easy to use. Test data can be downloaded from here.

wsi_fn = '/path/to/your/WSI/example/CMU-1-JP2K-33005.svs'
wsi_dicom_dir = "/path/to/your/output/example/CMU-1-JP2K-33005"

# # convert without compression
# p = parameters(JPEG_COMPRESS=False, image_levels=range(0, 3))
# wsi_c = WSIDICOM_Converter(wsi_fn, wsi_dicom_dir, p)
# wsi_c.convert()

# convert with compression
p = parameters(JPEG_COMPRESS=True)
wsi_c = WSIDICOM_Converter(wsi_fn, wsi_dicom_dir, p)
wsi_c.convert()
