Understanding DICOM Presentation Syntax

  • The SCU prepares an “Association Request” to define the SOP Class(es) to be transferred in the Association
  • For each SOP Class, the SCU defines possible TransferSyntaxes for each Object to be transferred
  • The SCU bundles multiple of these “PS” (SOP, TSs) entries into a single network transfer “request” and sends the request to the SCP
  • The SCP analyzes each PS and in its “Response”, the PS is accepted with a single TransferSyntax to be used by the SCU during data transfer or the PS is rejected
  • The SCU accepts this SCP contract and performs the Service of sending each Object to the SCP using an accepted PSID for that SOP and TransferSyntax
  • The SCP performs the Service with the Object
