Modalities send one whole image at a time to PACS.
PACS systems have multiple DICOM servers.
Using an F5/content switch speeds up image transfer times by directing modalities to the least busy DICOM server.
The database server is the brains of the PACS system.
The database server stores all the images sent to PACS on itself.
Order messages for pending exams are stored on the PACS database server.
All order messages are eventually matched up with images.
Most PACS systems have a single database server because it is not a critical component.
The time studies remain in the STS is fixed at 6 months in every PACS system.
Images stored in STS are retrieved and displayed to the user faster than images stored in the archive.
Network bandwidth has no effect on archive performance.
Radiologists are likely to be very understanding if it takes several minutes to pull comparison studies from a slow archive.
Mammo reading stations require different Barco monitors and have different Q/A requirements than general reading stations consequently they are a separate category of reading station.
What units ACQUIRE images from patients?
What units CREATE new images from raw images ?
post processing stations
Which PACS component processes DICOM send requests from the modalities?
What optional component sits between the modalities and the DICOM servers?
What is the purpose of an F5/content switch?
to direct DICOM association requests from the modalities to the least busy DICOM server
What is the purpose of the IMS?
to serve images out to review stations
Where is all the patient information stored in PACS?
What PACS component matches up order information with the images from the modalities using the accession number?
Where in PACS does the DICOM modality worklist server get the patient and order information to serve out to the modalities?
Two database servers connected by an Ethernet cable that mirror data between them would be what type of server configuration?
Which PACS component provides short term storage of images?
Another term for short term storage is
near line storage
Long term storage of images is provided by which PACS component?
The total volume of archive storage is commonly expressed in
To serve images out to a clinical review station via image links

Nas / archive
After receiving a request to send a study to a review station
what PACS components does the IMS have to connect with to locate the study?,database server / Nas or archive
For digital modalities such as US
CT and MR there is no need for an additional monitor because they have a modality console.,TRUE
Images are stored in the PACS database server.
The acquisition of images is sometimes considered part of the PACS especially if it is a CR or DR system.
PACS systems often have one single type of workstation.
All images are reviewed by a dedicated Q/A tech before being sent to PACS.
The purpose of the Q/A station is to
prepare the images for PACS
VNA stands for?
vendor neutral archive
What new technology is making exchange media obsolete?
electronic image exchange
What component of the PACS core is bought from a vendor other than the PACS vendor and provides enterprise archiving?
CD's DVD's and flash drives used to move images from one facility to another are part of which category?

What device deals with the creation and display of diagnostic reports.
What device is used to create a hardcopy image on paper or film?
The purpose of a preview monitor on a CR/DR unit is
to allow the tech to evaluate the image

Relay Station and Dictation Station
what is IMS
Image management server
what is iws
