21 ; This routine is invoked by the ^MAGDIR8 to update handle DICOM
22 ; CORRECT functions, that is, the "CORRECT" REQUEST item.
23 ;
24 ; This is a four-step process:
25 ;
26 ; 1) The "QUERY" record is sent, to obtain a list of corrected
27 ; images. The list is sent back to the gateway in a list of
28 ; "CORRECT" RESULT items, each with new patient/study values.
29 ; If the images are to be deleted, the list will contain "DELETE"
30 ; instead of "FIXED" RESULT items.
31 ; 2) The gateway processes each corrected/deleted image, one at a
32 ; time.
33 ; 3) The gateway sends a "PROCESSED | IMAGE" record is sent back to
34 ; the server for each corrected image, so that each can be
35 ; deleted from the list. (This is called an RPC Callback.)
36 ; 4) Finally, the gateway sends a "PROCESSED | STUDY" record back to
37 ; the server to delete the remainder of the study from the list.
