Diagram of an SCU SCP Set Up

SCU Connection SCP
DicomNet.Startup Initialize the DICOM DLL. This must be done before calling any DICOM Network Operations methods, but only needs to be done once per application. DicomNet.Startup
DicomNet() Create a DICOM Network object. DicomNet()
N/A The SCP listens for incoming connection requests. DicomNet.Listen
DicomNet.Connect ====> The SCU calls this method to connect to an SCP. This generates a call to this method on the SCP. DicomNet.OnAccept
DicomNet.OnConnect <==== The SCP creates a DICOM Network object for each connection it accepts. This allows the SCP to store information about this specific connection. DicomNet.Accept is called to accept the connection. This generates a call to this method on the SCU. DicomNet.DicomNet, DicomNet.Accept
N/A DICOM Network Connection established. N/A
DicomNet.SendAssociateRequest ====> The SCU calls this method to request a DICOM Associate connection. This generates calls to these methods on the SCP. DicomNet.OnReceive, DicomNet.OnReceiveAssociateRequest
DicomNet.OnReceive, DicomNet.OnReceiveAssociateAccept, or DicomNet.OnReceive, DicomNet.OnReceiveAssociateReject <==== The SCP calls DicomNet.SendAssociateAccept to accept the DICOM Associate connection. This generates calls to DicomNet.OnReceive and DicomNet.OnReceiveAssociateAccept on the SCU. DicomNet.SendAssociateReject is sent to reject the DICOM Associate connection. This generates calls to DicomNet.OnReceive and DicomNet.OnReceiveAssociateReject on the SCU. DicomNet.SendAssociateAccept or DicomNet.SendAssociateReject
N/A DICOM Associate Connection established. N/A
DicomNet.SendCStoreRequest ====> The SCU calls this method to request the storage of data. This generates calls to these methods on the SCP. DicomNet.OnReceive, DicomNet.OnReceiveData, DicomNet.OnReceiveCStoreRequest
DicomNet.OnReceive, DicomNet.OnReceiveData, DicomNet.OnReceiveCStoreResponse <==== The SCP calls this method to respond to the storage request. This generates calls to these methods on the SCU. DicomNet.SendCStoreResponse
DicomNet.SendReleaseRequest or DicomNet.SendAbort ====> The SCU calls DicomNet.SendReleaseRequest to request a release from the DICOM Associate connection. This generates calls to DicomNet.OnReceive and DicomNet.OnReceiveReleaseRequest on the SCP. This is the preferred way of closing a connection. DicomNet.SendAbort can also be called to close a connection. This generates calls to DicomNet.OnReceive and DicomNet.OnReceiveAbort on the SCP. DicomNet.OnReceive, DicomNet.OnReceiveReleaseRequest or DicomNet.OnReceive, DicomNet.OnReceiveAbort
DicomNet.OnReceive, DicomNet.OnReceiveReleaseResponse <==== The SCP calls this method to respond to the release request. This generates calls to the following methods on the SCU. DicomNet.SendReleaseResponse
DicomNet.Close ====> The SCU calls this method to close the DICOM Associate connection. This generates a call to this method on the SCP. DicomNet.OnClose
DicomNet.Shutdown When the DICOM DLL is no longer needed, call this method to shut down the DLL and free all associated memory. This method should be called once for every call to DicomNet.Startup. DicomNet.Shutdown
