Modality Performed Procedure Step (PPS)

Theory of Operation
Once activated, the PPS function essentially performs background tasks to exchange information with
the configured PPS SCP. This function is activated for both routine and stereotactic (if the option is pres-
ent) examinations.
When the Viewer is started and after the first image has been acquired, an initial PPS message is sent
from the AWS to the PPS SCP to inform it that the examination is now in progress. This message also
contains the patient and clinical data stored in the worklist entry used to launch the Viewer. These data
can either have been downloaded from a worklist server or entered manually on the AWS itself.
When the Viewer is closed, a second PPS message is sent to the PPS SCP to update the examination
data with the following information:
•
A user-selected exit status (see Section
5 PPS in the Viewer on page 97
•
A list of the images that will be automatically sent, via the Auto Push feature, to the associated Image
Archiver or CAD.
Note:
In order for the PPS messages to be sent, the Auto Push feature from AWS to the associated Im-
age Archiver or CAD must be activated.
Note:
In case some images have been excluded from the Auto Push list (e.g. using the Quality Check
feature) those images will not be listed in the PPS messages sent to the PPS SCP.
•
The cumulative AGD (Average Glandular Dose) calculated based on the AGD estimation available
for images acquired in AOP. This dose per examination estimation is computed using the following
rules:
•
Images that have been acquired and excluded from the Auto Push list (e.g. using the Quality
Check feature) are accounted for in the overall dose value.
•
Images acquired in Manual Mode are not accounted for, as no dose estimation is available for
them.

Special Configuration for CAD Workflows
If a mammography CAD system is available, the PPS function can be configured to send specific PPS
messages to the PPS SCP of the CAD system itself. This configuration might be needed to suit specific
needs related to the CAD system or to suit the case where different image lists are sent to the CAD and
the Image Archiver.

PPS Configuration
PPS configuration is accessed by clicking the
Tools menu
button and selecting
PPS Management
as
explained in section
8 Tools menu utilities on page 72
! Notice:
The
PPS Management
panel is not intended for use by operators of the Senographe DS, and
therefore is not described here. Refer to your Field Service Engineer (or possibly your local net-
work administrator) for assistance on setting up PPS hosts, as uninformed use may lead to unpre-
dictable results.
