Ch. 9 PACS Test Flashcards
PACS stands for:
picture archiving and communication system
DICOM was first released in
1985
The fundamental parts of PACS are:
- image acquisition
- display workstations
- archive server
T/F - Any computer used to view digital images is a display workstation.
true
T/F - Display workstations will always have some form of PACS software.
true
The central part of PACS, this houses both historic and current data.
archive server
How a process is done step by step, or how a task is completed.
workflow
Defined as the hardware and software infrastructure of a computer system.
system architecture
The three common PACS architectures are:
- client/server
- distributed
- web-based
T/F - Client-based systems allow for images to be viewed from any workstation without any other intervention.
true
T/F - Client-based systems allow multiple users to read the same study at the same time.
false
These PACS systems are also known as stand-alone models.
distributed
In distributed systems, images are stored ___ until they are pushed to the archive.
locally
T/F - Web-based PACS allow for greater hardware flexibility.
true
T/F - CRT monitors weigh much less than LCD monitors.
false
T/F - LCD monitors require less maintenance and can be used in areas with greater amounts of ambient light.
true
The number of pixels contained in a display.
resolution
T/F - Mammography exams must be read on a 4K resolution monitor.
false
T/F - CT exams can be read on a 1K resolution monitor.
true
T/F - Radiologist reading stations will have the best possible monitors and hardware available.
true
____ define how a set of images will be displayed on a monitor
hanging protocols
This term means to move through a series of images frame by frame.
cine
ROI means:
region of interest
In which type of workstation can changes not be made to the patient demographics of an image set?
review station
What workstation function will allow the user the ability to arrange a certain number of images per monitor per modality?
hanging protocols
T/F - In a web-based system, images are sent directly from the modality to a display workstation for image interpretation.
false
Which advanced image manipulation function will allow the radiologist to view several different anatomical planes from the original acquired sagittal images?
multiplanar reconstruction
Which advanced image manipulation function will allow the technologist to join multiple images together as one?
stitching
DICOM stands for:
digital imaging and communications in medicine
Options available on the workstation that allow movement through menus, menu options, and image processing choices, as well as movement through a series or stack of images and/or patient image folders.
navigation functions
T/F - Digital images displayed on a workstation would be considered hard copy.
false
T/F - Digital images that have been printed and are displayed on a lightbox would be considered hard copy.
true
