DICOM Writer

The DICOM Writer is a post-processor that converts MHD files into DICOM files.

Each MHD file should be named after the Series Instance UID associated with its original DICOM series (e.g. 1.2.826.0.1.3680043.2.1125.1.30521143073416610365663301213782755.mhd). Each MHD file is converted into a series of DICOM files which are output to a specified directory. Each DICOM file is named with an auto-generated UID. The output directory is subsequently consumed by the Clara DICOM Adapter.

Docker

Before running the container, use docker pull to ensure an up-to-date image is installed. Once the pull is complete, you can run the container image as part of a workflow.

Run DICOM Writer with the following steps:

1. In the Tags section, locate the container image release that you want to run.

2. In the PULL TAG column in the table, click the icon to copy the docker pull command.

#. Open a command prompt and paste the pull command. The pulling of the container image begins. Ensure the pull completes successfully before proceeding to the next step. #.

            

            
mkdir -p DICOM mhd output
        

1. Copy DICOM files to the dicom folder and mhd files to the mhd folder with the following commands:

   Copy

   Copied!

               
   
               
   # Copy DICOM files to the DICOM folder
   cp -r /path/to/dicom/files dicom
   
   # Copy mhd files to the mhd folder
   cp -r /path/to/mhd/files mhd
           

   The DICOM Writer converts mhd files in the mhd folder to DICOM files in the output folder using headers from the DICOM files in the dicom folder.

2. Run the DICOM Writer with the dicom, mhd and output directories with the following command:

   Copy
