Is there any orthanc plugin available to support the storage (read, write and delete) of rawdata of MRI / PET/ ECG with tags? The storage can be filesystem and R/W operations shall be synchronized with corresponding DICOM images.
You can attach rawdata to DICOM instances thanks to the so-called “attachments” mechanism that is built in Orthanc:

Note that the DICOM instance must first be imported into Orthanc, then the rawdata can be attached (i.e. it is not possible to store rawdata without an “anchor” DICOM instance).
