The full name of a system, consisting of its local host name and its domain name, including a top-level domain. For example, venera is a host name and venera.isi.edu is a fully qualified domain name. A fully qualified domain name should be sufficient to determine a unique Internet address for any host on the Internet. This process, called name resolution, uses the Domain Name System (DNS).

Hospital Information System. The database used by a hospital to manage patient information and scheduling.
An option that forces the PACS to verify all incoming images from an acquisition station or modality against specific criteria, such as the patient ID and accession number. The PACS sends a message through the RIS Gateway to verify the criteria against what is contained in the HIS. If the criteria match, then the images can be stored permanently.
Stands for Health Level 7, a standard communication protocol used for the transmission of medical information. HL7 is used primarily by HIS systems and does not support transmission of images.
Defines when orders for scheduled studies are sent from the RIS or connectivity component to another system, such as a modality, in the Radiology department. Generally, the horizon value is defined as “hours before” the scheduled start time.
The host name is a common alphanumeric alias for the IP address of a server.
Hypertext transfer protocol, a TCP-based protocol for transferring hypertext requests and information between servers and browsers.
Hypertext transfer protocol, secure, a URL access method for connecting to http servers using SSL (secure sockets layer).
Stands for Integrating the Healthcare Enterprise. IHE is an initiative by healthcare professionals and industry to improve the way computer systems in healthcare share information. IHE promotes the coordinated use of established standards such as DICOM and HL7 to address specific clinical needs in support of optimal patient care.
Internet Information Services. A set of programs for building and administering websites, a search engine, and support for writing web-based applications that access databases.
The Internet Protocol address is a numeric address that identifies the station to other TCP/IP devices on the network.
Lightweight Directory Access Protocol, the technology for storing user names and IDs, passwords, and user-related preferences. This information is stored in an LDAP depository.
Distributing processing and communications activity evenly across a computer network so that no single device is overwhelmed.
A file or set of files containing a record of the actions and modifications made in an application. Service teams use log files during setup and configuration of the system or its components. Logs are also used to diagnose problems. Logging can typically be set to record varying levels of detail.
Media Access Control address. The unique physical address of each device’s network interface card.
Mitra Common Framework.
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.
Modality Performed Procedure Step. MPPS is a mechanism used by modalities to report the status of an acquisition. MPPS messages indicate whether the acquisition (or study) is in progress, completed, or canceled.
Refers both generally to the Agfa IMPAX PACS system and specifically to the name of the IMPAX Server database.
MWL = modality worklist, the list of studies that are scheduled for a particular modality. The technologist works from this list to minimize data entry errors and ensure data integrity. For example, a modality worklist can include the patient name, patient ID, accession number, scheduled procedure, and scheduled date and time for the study.
The Network Gateway is part of the IMPAX MVF cluster. Essentially, this is the workflow manager of the IMPAX 6.0 and later 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.
Open Database Connectivity. A standard protocol for accessing relational databases based around SQL.
A Picture Archive and Communication Systems (PACS) makes it possible to electronically store, manage, distribute, and view images.
A hospital-wide unique identifier for a patient. Also called a Medical Record Number (MRN).
A physical hardware interface for connecting external devices to a computer, or it can be understood as a software interface for network communications.
Language in which two systems communicate. For example, DICOM, HL7, and SQL are all protocols.
Any station that can be accessed over the network. A PACS, display station, HIS, RIS, or CIS are examples of remote stations. In an enterprise solution, remote stations may also be thought of as those connecting to the network through the Internet, rather than through any direct in-hospital or on-campus connections.
Radiology Information System. Responsible for scheduling exams and for report management in the Radiology department.
A collection of users or other roles that holds IMPAX Client permissions and preferences as well as licensing options. For example, a role can represent the enterprise, the institution, a department, or a team.
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.
A type of resource, referring to the overall hospital facility that houses departments, locations, specialties, and stations.
Smart cards, sometimes called chip cards, contain a computer chip embedded in the plastic. When read by special terminals, the cards can perform a number of functions or access data stored in the chip. These cards can be used as ID cards with stored-in passwords.

Simple Partial File Transfer Protocol. A proprietary transport protocol for communication within the IMPAX cluster.
A digital certificate with the SSL protocol that has been issued by a certificate authority.
Type of resource. A station resource is a real world device on the PACS network, such as a modality or PACS.
Within the context of the IMPAX Client configuration interface, refers to a computer that has the IMPAX Client installed. Stations can be in a radiology reading room, in the offices of clinicians, or in the homes of radiologists, for example. When a user logs into IMPAX for the first time, the computer name is listed in the navigation pane of the Configure area - Stations section. Stations are organized under station containers. You can set configuration options, such as diagnostic monitor settings, memory usage, and so on, for a specific station, or the station can inherit its configuration from the station container.
A group of database operations combined into a logical unit of work.
Transaction (tx) objects are DICOM objects used to communicate and synchronize study status changes across multiple IMPAX clusters.
Unique Uniform Resource Locator. Address of the form http://www.site_name.com/, used to point your web browser at a specific location on the Web.
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 permissions, licenses, and preferences from their role.
A component that runs on a web server and allows programs to request and receive data over HTTP or HTTPS.
