It runs as a daemon serving requests from other applications to send the PPS information to the remote AE and return the results to the requesting application. The PPS Server AE initiates the following functions.

GE HEALTHCARE DIRECTION DOC0500644, REV 4 STATEMENT DISCOVERY, LIGHTSPEED AND BRIGHTSPEED DICOM CONFORMANCE • At the end of image acquisition, system initiates a ‘Complete PPS’ or ‘Discontinue PPS’ based on the choice selected by the user using the user interface provided. The user is also given a choice ‘Defer PPS’ which is described below. PPS Server AE initiates a MPPS N-SET request to the remote AE, in-order to update the MPPS SOP instance that is already created.
PAGE 105
GE HEALTHCARE DIRECTION DOC0500644, REV 4 LIGHTSPEED* DICOM CONFORMANCE STATEMENT • The remote AE returns response indicating the success/failure of the request execution. The PPS state information is updated in the system based on the response data, and is presented to the user. • At the end of image acquisition, if the user has chosen ‘Defer PPS’, the user is provided with an interface to ‘Complete PPS’ or ‘Discontinue PPS’ at any later time.
