Revised 8910 Flashcards
A place where records or documents are persevered
Archive
Storage for all patients and images are found on a
Magnetic type of optical disk
- Contains master aricheve database
- controls receipts, retrieval, and distribution of images and DICOM
Image manager
Consist of physical storage of the archive system
Image or archive storage
3 tiers levels of archive
- Short term
- Midterm
- Long term
(pacs are set up with long or short term teir )
- online or available quickly
- within 3-5 sec
Short term
Near line that must be retrieved from tape or disk and brought to RAIDs
- 1-5mim
Long term
Redundant arrays of independent
RAIDs
Composed of several magnetic disk or hard drives that link together in arrays
RAID
- Similar to dvd / cd
- Read with Laser
- House plastic cartilage
Reliable / long term storage option
MOD - MAGENTO OPTICAL DISK
- new generation of MOD
- use blue laser tech
Ultra density optical
Three things common in MIMPS
1.Film digitizer
2. Printer
3. Cd burner
- laser technology
- ccd technology
- scans the analog flim and produces numeric signals form each scan
Flim digitizer
2 Types of imagers
Wet (chemical) and dry laser imagers
Two or more object SHARING resources and info
Network
Network geographic classifications 2
- LAN- local area network
- WAN- wide area network
Two typical network classifications
- Peer to peer
- Server or client based
SMALL area network with series of cables / wireless access points
- share info and devices of same network
- less expensive
- ## faster than wan
LAN - local area network
Wide area network span a large area, city, states,or the world
- connects computers that aren’t physically attached ( like internet)
WAN- wide area network
-This computer network is considered equal
- controls its own info/ operation
-popular for small office or home
Peer to peer network
( least expensive and simple )
Centralized computer controls the operations, files, sometimes programs of computers attached to network
Served based network
- similar to server based network
- centralized computer controls operation
- network device that requests services and resources from server
Client based network
Computer that manages resources for other computer, servers, and networked devices
Server
Found on a network that requests services and resources from a server
- relies on network
Thin client
- Computer that can work independently from the network
- process and manage its own files
- found in sectional imaging modality workstation
Thick client
Devices are connected via some sort of communication medium
Network connectivity
Four types of physical connections or communication mediums
- Coaxial cable
- Twisted pair wire
- Fiberoptic cable
- Electromagnetic wave
- Similar to tv cable wiring
- consist of center conducting wire surrounded by insulation and grounded shield braided wire
- sturdiest wire
Coaxial cable
-Similar to telephone wire
- made of copper wire
- common connection medium for LAN
Twisted pair wire
- glass thread to transit data on network
- expensive, fragile, and fast
- used in infrastructure network
Fiberoptic cable
Connection is via infrared or radio frequency
- no physical cable needed
Wireless connections
-Simplest device connecting several pieces of equipment
- several wring ports to receive and pass on data
- used in small office or houses
Network hub
Sends data only to devices which the data are directed
- not used in houses or small offices
Network switch
Created so larger network can be segmented to reduce traffic
Network bridge
-More sophisticated
- read portion of the message and directs them to their intended target
Network router
Device communicate through a communication medium
- ex one type of address: IP address
Network communications
Data travel along network using an agreed upon set of RULES
network protocol
Physical geometric layout of the connected device on a network
Network topology
Four common topological configurations
- Bus
- Ring
- Star
- Mesh
Device are physically attached to and listen for communication on ONE wire
- if it breaks, entire network is down
- wire single point of failure
Bus
Device are connected in a CIRCLE
- always in same direction
- if breaks, it halts the network
Ring
Star
Consist of multiple pathways of interconnecting devices and networks
Mesh
Holds patients full medical info from hospital billing to the inpatient ordering system
HIS- hospital info system
Hold all patient data from scheduling info to transcribe report
RIS - radiologist specific patient
- A part of HIS
- contains all patient records
EMR - Electronic medical records
