User guide

modality
An imaging discipline, such as CT, or a device
that gathers digital information, such as
digitizers for X-ray film, MRI scanners, and CR
devices.
MVF
Name of the IMPAX Server database.
N
Network Gateway
The Network Gateway is part of the IMPAX
cluster and may be housed on its own computer
or may share the same computer as the Archive
and Database Servers. Essentially this is the
workflow manager of the IMPAX system. The
Network Gateway controls the studies coming
into the cluster from an acquisition station,
validates these incoming studies against
information from the HIS or RIS, and routes the
validated studies to cache or archive.
non-jukebox archive
Functions much like a jukebox archive, except
that it has no mailslots or changer. In a
non-jukebox archive configuration, a volume
is considered to be offline when it leaves the
drive, whereas in a jukebox configuration, the
volume is considered offline when it leaves the
jukebox—either via a mailslot or by manually
reaching in the case and retrieving the volume.
O
OCR
Optical Character Recognition is the recognition
of printed or written characters by a computer.
If a modality generates images into the system
but not enough information about a study is
sent, OCR templates read information directly
from the burned demographics.
P
PAP
PACS Archive Provider. A PACS Archive
Provider (PAP) acts like a Service Class Provider
(SCP) in that it receives studies. However, it
differs from an SCP in that the PAP can
automatically register a study as PACS archived
if the study originates from a source that the
PACS stores to and remembers from, without
having to queue the study for archiving back to
the source. The PAP can also parse the private
tags of the incoming DICOM objects to
determine HIS verification and study status.
permissions
Permissions define the available IMPAX features
and types of studies that users in a particular
role have access to. Permissions are made up
of a set of operations.
PSARMT
PACS Store and Remember Migration Tool. This
tool enables a site to migrate from an external
PACS system to IMPAX by allowing the external
system to act as an archive server to IMPAX.
S
SCP
Service Class Provider. A DICOM server that
receives requests from an SCU. The DICOM SCP
accepts images for processing, processes find
and retrieve requests, and handles storage
commitment requests and replies.
SCU
Service Class User. Primarily sends DICOM
requests to an SCP.
T
tx objects
Transaction (tx) objects are DICOM objects used
to communicate and synchronize study status
changes across multiple IMPAX clusters.
U
user
Users represent individuals, such as a
radiologist or a clinician. Each user must belong
to at least one primary role. A user can also
belong to other secondary roles. Users inherit
