Hi,

Have you check this option ?

// If this option is set, Orthanc will transparently transcode any
// incoming DICOM instance to the given transfer syntax before
// storing it into its database. Beware that this might result in
// high CPU usage (if transcoding to some compressed transfer
// syntax), or in higher disk consumption (if transcoding to an
// uncompressed syntax). Also, beware that transcoding to a transfer
// syntax with lossy compression (notably JPEG) will change the
// "SOPInstanceUID" DICOM tag, and thus the Orthanc identifier at
// the instance level, which might break external workflow.
/**
   "IngestTranscoding" : "1.2.840.10008.1.2",
**/

Setting it to 1.2.840.10008.1.2.4.70 should reduce the size of images by a factor of 3 while not reducing quality.

HTH,

Alain.
