10.2. Clara DICOM Writer
The DICOM Writer is a post-processor that converts an MHD file into DICOM files.
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. Each MHD file should be named after the Series
Instance UID associated with its original DICOM series (e.g.
1.2.818.104.22.16880043.2.1125.1.30521143073416610365663301213782755.mhd). The output directory is subsequently consumed by the Clara DICOM Adapter.
