Carter & Veale 8-10

QuestionAnswer
first version of DICOM was created when? 1985
three fundamental parts of PACS image acquisition Display workstations Archive Sensors
reading images on the computer without hardcopy films softcopy reporting
any computer used to view a digital image workstation
most interactive part of a PACS workstation
used inside and outside of the radiology department workstation
file room of the PACS archive servers
central part of PACS archive server
may also serve as the central node that receives all images before interpretation archive server
how a process is done step by step or how a task is completed work flow
hardware of the software infrastructure of the systems workflow system architecture
PACS system architecture normally consists of: acquisition devices storage display workstations image management system
images sent directly to the server after acquisition and centrally located client/server based systems
displays workstation function as a client of the archive server and accesses images based on a centralized worklist client/server based systems
advantages of a client/server based system any exam sent to PACS, Only 1 can read, no need to pull or send historical images
disadvantages of client/server based system archive server single point of failure, archive down- entire system down, new images must remain at modality until archive is up and can receive, system network independent, network bogged down
acquisition modalities send images to designated reading station and possibly to review stations. Images stored locally & sent to archive after being read. distributed systems (standalone systems)
advantages of distributed system archive can go down with no impact on workstation, after archive comes up images auto update, PACS less likely to be lost, system less dependent on network for speed
disadvantages of distributed systems personnel rely on system to perform image distribution correctly, each workstation has different worklist, rad have to move to another workstation to read, possible for 2 rad to be reading same image, paper important
similar to client/server system except images are held centrally and application software loads to the lient display. web-based system
advantages of web based system hardware is anything that will support web browser, greater flexibility with hardware, can be on site or teleradiology
disadvantages of web based system system limited because no locally installed hardware, monitor may not be of diagnostic quality, bandwidth limiting, some programs to large to transmit across network
consists of a monitor, computer, mouse, and keyboard display workstation
has the highest resolution monitors radiologists
has the second best resolution monitors physicians
has the third best monitors, used to review images after requisition but before completion technologists
has the poorest quality monitors, used to look up exam and print copies file room/image management stations
common navigation functions navigation, handing protocols, study navigation
common image manipulation and enhancement functions window/level, annotations, flip and rotate, pan, zoom & magnify, measurements
historical collection of images stored in PACS archive
contains master database of everything in archive. Controls receipt, retrieval, & distribution of images it stores. controls all DICOM processes, interfaces with HIS & RIS Image manager / controller
2 components of PACS archive Image manager/controller Image storage/sever or archive server
consists of physical storage device of the archive system; it commonly consists of 2 or 3 tiers of storage Image storage/sever or archive server
archive considerations system need, cost, compatibility, alternatives
device the scans hard copy x-ray images and converts them to digital images film digitizer
2 types of film digitizers laser film digitizers & CCD
uses helium neon laser beam to convert analog film image into digital image laser film digitizers
uses fluorescent bulbs that shine through the film and CD array that detects the light and transforms into electrical signal & ADC turns into digital image CCD film digitizer
uses for digitizers teleradiology, comparing outside or old films, film duplication, computer aided diagnosis (CAD)
ways to output copies of films wet (chemical) laser images dry laser images (use heat) CD/DVD burner
what does the archive server consist of in PACS? database server, or image manager short term & long term storage workflow manager
in which system architecture is it possible for two radiologists to be reading the images at the same time and be unaware of the other Distributed System
what system architecture stores the images AND application software centrally web based system
one of the greatest advantages of PACS ability to view same set of images in multiple locations at one time
