-  The Storage Application Entity sends images, Stru
ctured Reports and requests Storage Commitment to a 
remote AE. It is associated with the local real-world  activities “Acquire” for Send As You Go, “End Exam” for 
“Batch”, “DICOM Send” for Manual or “SEND” fr om Exam Directory. Commitment requests are made

automatically.    Methods to send images depend on user configuration, “Batch”, “Send 
As You Go” or “Manual”.   
“Manual” mode is performed upon user request for each  study or for specific images selected.    “Batch” mode 
starts to send images at End Exam for each study.    “Send As You Go” mode starts when the first image is 
acquired for each study and images are tr ansferred immediately after acquisition.     
Structured Reports are sent at End Exam for each st udy, or from Exam Directory, selecting “SEND”. 
If the remote AE is configured as an archive device,  the Storage AE will request Storage Commitment and if a 
commitment is successfully obtained, it will record this in formation in the local database and displayed it in the 
Exam List. 
-  The Workflow Application Entity re ceives Worklist information from and sends MPPS information to a remote 
AE. It is associated with the local real-world activities  “Search” and “Acquire Images”. When the “Search” local 
real-world activity is performed, the Workflow App lication Entity queries a remote AE for worklist items and 
provides the set of worklist items matching the query r equest. “Search” is performed as a result of an operator 
request, at system Startup, or can be performed automatic ally at specific time intervals.  When the “Acquire 
Images” local real-world activity is performed, the Workflow Application Entity creates and updates Modality 
Performed Procedure Step instances managed by a remote  AE. Acquisition of images will result in automated 
creation of an MPPS Instance. Completion of the M PPS is performed at End Exam for each study.    No 
Cancel is available. 
-  The Hardcopy Application Entity prints images on a remo te AE (Printer). It is associated with the local real-
world activity “Acquire” when a DICOM printer is configur ed, “Print” from the Exam Directory or “DICOM Print” 
from Image review.    Methods to film images depend on us er configuration and are equal to the actions of 
sending images of the Storage Application Entity.   
4.1.2  Functional Definition of AE’s 
4.1.2.1  Functional Definition of Storage Application Entity 
The existence of a send job with associated network destinati on will activate the Storage AE. An association request is 
sent to the destination AEs and upon successful negotiation of  a Presentation Context, the image transfer is started. If 
the association cannot be opened, the re lated send job is set to an error state and can be restarted by the user via 
DICOM manager interface or automatically. An automatic retr y (retry interval, retry count) can be configured using the 
Setup/DICOM Menu. 
4.1.2.2  Functional Definition of Workflow Application Entity 
Worklist Search attempts to download a Worklist from a remote node. If the Workflow AE establishes an association to 
a remote AE, it will transfer all matching worklist items via the open Association.    By default, Worklist Update use “US” 
for Modality, current date for Scheduled Procedure Step Start Date and blank for Scheduled Station AE Title as query 
parameters.    The results will be displayed in a separate list, which will be cl eared with the next Worklist Seach. 
Additional search parameters include: 
•  On Statup and Every x minutes, with x allowed to be 1 – 60, default of 5 
•  Scheduled Station AE Title 
o Any 
o  This Station 
o  Another 
•   Scheduled Procedure Step Start Date 
o Today (default) 
o   Range (Prior 0 (default); Next 0 (default) with Prior and Next range of 1-60 days 
o  Past Week

o
 Past Month 
o   Custom (specific Date, single value matching) 
The Workflow AE performs the creation of an MPPS Instance automatically whenever the  first image is acquired for 
each study.    The MPPS final states can only be set by “End Exam” for each study. 
4.1.2.3  Functional Definition of Hardcopy Application Entity 
The existence of a print job will activate the Hardcopy AE.    An association is established with the printers and the 
printer’s status determined.    If the printer is operating normally, the film sheets described within the print job will be 
printed.    If the printer is not operating normally, the print j ob will set to an error state and can be restarted by the user 
via DICOM manager interface or automatically.    An automatic  retry (retry interval, retry count) can be configured using 
the Setup/DICOM Menu.

Under normal scheduled workflow conditions, the sequencing constraints are illustrated in  Figure 4.1-2 and Figure 
4.1-3 . 
Other workflow situations (e .g. unscheduled procedure steps) will have ot her sequencing constraints. Printing could 
equally take place after the images acquired have been stored.  Printing could be omitted completely if no printer is 
connected or hardcopies are not required.

4.2.1.3 Association Initiation Policy 
4.2.1.3.1  Activity – Send Images and Structured Reports and Request 
Commitment 
4.2.1.3.1.1  Description and Sequencing of Activities 
A user can select exams or images and request them to be se nt to some destination.    Each request is forwarded to 
the job queue and processed individually.    When the “Batch ” or “Send As You Go” option is active, Stored images and 
reports will be forwarded to the network job queue for a pre- configured auto-send target destination automatically.    For 
“Batch” and “Manual” configuratio n, the system opens an association, send s all images in the study, and closes the 
association.    If “Send As You Go” is se lected, the system handles the associat ion with the Storage SCP Server using 
the following method. 
a.  Open an Association when the first image is acquir ed, and keep association open until the study is closed. 
b.  If an error occurs while sending an image to the server because there is no longer an open association  (server timed-out), attempt to re-establish the association. 
c.  When the study is closed, the  open association closes after images  remaining in that study are sent. 
Structured Reports are only sent over a separate association at End Exam. 
If the remote AE is configured as an archive device, the  Storage AE will, after all images and reports have been sent, 
transmit Storage Commitment request (N-ACTION) over a sepa rate Association. The Storage AE can only receive an 
N-EVENT-REPORT request in  a subsequent association initiated by the SCP.

A possible sequence of interactions between the Storage  AE and an Image Manager (e.g. a storage or archive device 
supporting the Storage and Storage Commitment SOP Classe s as an SCP) is illustrated in the figure above. 
NOTE: The N-EVENT-REPORT must be sent over a separate association initiated by the Image Manager. (See 
Section  4.2.1.4)

configurable. 
4.2.1.3.1.4 SOP Specific Conformance for Storage Commitment SOP Class 
4.2.1.3.1.4.1  Storage Commitment Operations (N-ACTION) 
The Storage AE will request storage commitment for the conf igured device for instances of the Ultrasound Image, 
Ultrasound Multi-frame Image and Structured Report Storage SOP Classes. 
The Storage AE will consider Storage Commitment failed if  no N-EVENT-REPORT is received for a Transaction UID 
within a configurable time period afte r receiving a successful N-ACTION response (duration of applicability for a 
Transaction UID). 
The Storage AE does not send the optional Storage Media  FileSet ID & UID Attributes or the Referenced Study 
Component Sequence Attribute in the N-ACTION. 
The Behavior of Storage AE when encountering status codes in  an N-ACTION response is summarized in the Table 
below:
