Worklist queries for Modality (U S) or  modalities may be initiated by the  user or will occur at a preset interval set 
as one of the following:  
•  User may press “Refresh Now” to send a query: us ing the Start Date, Modality and AE Title selections 
made in the Modality Worklist Customizable Queries configuration page. 
•   The user may configure the system to search for st udies scheduled for its AE Title, or it may be set to 
search for a different AE Title’s studies, or all. 
•   The system may be set* to periodically poll the workli st server.  Default is 10 minutes, adjustable in one 
minute increments from 1 to 32,767 minutes.

4.2.2.3.2 Activity –Acquire Images 
4.2.2.3.2.1 Description and  Sequencing of Activities 
An Association to the configured M PPS SCP system is established immediatel y after the first image is acquired to 
send the MPPS N-Create message wi th status of “IN PROGRESS”. 
The “Close Study” button causes a “COMPLETED” status  in the N-Set message. An exam for which an MPPS 
Instance is sent with a state of “COMPLETED” can no  longer be updated. However, the exam may be appended.  
The “Cancel Exam” function causes a “DISCONTINUED” mess age. An exam for which an MPPS Instance is sent with 
a state of “DISCONTINUED” can also no longe r be updated. However, the exam may be appended. 
The system supports creation of “unscheduled cases” by allowing MPPS Instances to be communicated for locally 
registered Patients. 
The system performs a single Performed Procedu re Step at a time per Scheduled Procedure Step. 
HD7/HD7XE 3.0 will initiate an Association to issue an:   
—  N-CREATE request according to the CREATE Modality Pe rformed Procedure Step SOP Instance operation or a 
—  N-SET request to finalize the contents and state of the MPPS according to the SET Modality Performed Procedure  Step Information operation. 
  The opening of a study  marks the beginning of a new Modality Performe d Procedure Step (MPPS).  At this time, a 
MPPS record is created on the MPPS SCP through the  use of the N-CREATE service.  If the MPPS SCP is 
unavailable at this time, the request is queued and will be sent when the MPPS SCP is available. 
When the user ends the scheduled procedure by closing the study and savi ng any changes, the MPPS status is 
“Completed”.  Alternatively, the user  may choose to cancel acquisition, the study is saved in local storage and the 
MPPS status becomes “Discontinued”.  At this time, the Study Management AE  attempts to modify the MPPS on the 
MPPS SCP through the use of the N-SET service.  If the  MPPS SCP is unavailable, the request is queued and will be 
sent when the MPPS SCP is available.

Table 28 summarizes the behavior of HD7/HD7XE 3.0 when encountering status codes 
in an MPPS N-CREATE or N–
SET response.  
The updated attributes are shown in Table 30 below. The “N- CREATE Usage” column shows the attributes transmitted 
when the status of the study chang es to “IN_PROGRESS”. The “N-SET Usage” column shows the attributes 
transmitted when the status of  the study changes to “COMPLETED” or “DISCONTINUED”. 
Note: The following fields are copied from the  selected MWL entry to the Patient ID screen: 
Accession Number, 
Patient’s Name, 
Patient’s ID, 
Patient’s Birth Date 
Patient’s Sex 
Referring Physician’s Name 
Study description 
Usually, the performing physician will accept  the information in the Patient ID Screen, as is, however the physician / 
operator has the option of editing the info rmation before starting the study.  If the physician edits this information then 
the MPPS N-CREATE command that is sent to the MPPS server on study start will use the edited information and not 
the original MWL information.
