GHDX2-ADA DICOM Storage and Archive Appliance Admin Guide
67
MD5
An algorithm that is used to verify data integrity through the creation of a 128-bit message
digest from data input (which may be a message of any length).
Modality
Any of the various types of diagnostic or treatment equipment or probes used to acquire
images of the body such as CT, MR, Ultrasound, X-Ray, etc.
PACS
In medical imaging, picture archiving and communication systems (PACS) are computers or
networks dedicated to the storage, retrieval, distribution and presentation of images. The
medical images are stored in an independent format. The most common format for image
storage is DICOM (Digital Imaging and Communications in Medicine).
Patient Identifier
PID or Medical Record Number (MRN) is a hospital-wide patient identifier which can contain
any alpha-numeric character.
Port Number
In network communications, stations are identified by both a hostname and a port number.
The port number can be thought of as a specific channel on the station where the network
message is sent. Port numbers allow different applications on the same computer to use
network resources without interfering with each other.
RIS
Radiology Information System is a paperless patient record system used by radiology
departments to store, manipulate and distribute patient radiological data and imagery. The
system generally consists of patient tracking and scheduling, result reporting and image
tracking capabilities.
Study
A collection of images/reports acquired from a particular patient at a particular point in time.
A Study may consist of one or more series.
Series
A group of one or more images obtained from the same modality type and acquired on the
same imaging equipment sequentially in time.
Teleradiology
Teleradiology is the electronic transmission of radiological patient images, such as x-rays,
CTs, and MRIs, from one location to another for the purposes of interpretation and/or
consultation. Typically this is done over standard telephone lines, wide area network (WAN),
or over a local area network (LAN). Through teleradiology, images can be sent to another
part of the hospital, or to other locations around the world.
