Q

Disaster Recovery

A

keeping complete archive of images offsite in case of emergency

17
Q

Electronic version of radiologist’s reading room

A

PACS

18
Q

Digital Imaging and Communications in Medicine (DICOM)

A

Universally accepted standard(language) for exchanging medical images between the various modalities and PACS.

19
Q

First version of DICOM completed

A

1985

20
Q

DICOM:

A

Universally accepted standard
Laid the groundwork for the future development of integrated PACSs.
Now every modality and PACS communicates via DICOM.
Each vendor and modality boasts DICOM compatibility.

21
Q

Each DICOM statement must be read carefully to

A

determine the extent of the compatibility

22
Q

File room for PACS

A

Archive servers

23
Q

Archive servers have:

A
  • Database server or image manager
  • Short-term and long-term storage

-Workflow manager

24
Q

Central part of PACS

A

Archive servers

25
Q

Houses all historic and current data

A

archive servers

26
Q

May also serve as the centralized node that receives all images before interpretation

A

Archive Servers

27
Q

Archive Query allows for:

A

Function allows retrieval of images from the PAC system based on the following:
- Date of exam
- Patient name or number
- Exam number
- Pathologic condition
- Anatomic area

28
Q

Image Acquisition

A

Images are acquired in a digital format
- US
- CT
- MRI
- Nuc med
- CR
- Mammo

29
Q

Image Aquisition Modality things

A

Ultrasound : Early ultrasound mini-PACS networks became a norm in many hospitals

Computed Tomography (CT): As the images sets increased in number, this necessitated the transition to soft-copy reading

Magnetic Resonance Imaging (MRI): As with CT as the numbers of images increased, reading on a monitor became a good alternative.

30
Q

Workflow

A

How a process is done step by step or how a task is completed

How one completes an exam from order entry to transcribed report

Diff in every department

Laser printers and dry processors

33
Q

Soft-Copy

A

Flat screen monitors
Many advantages

34
Q

Display Workstation

A

any computer used to view a digital image

  • Most interactive part of a PACS.
  • Used inside and outside of the radiology department.

-Hands-on Component
-Diff hardware requirements for each system

35
Q

Display station

A
  • Receives images from archive or various radiology modalities
  • Presents images to be viewed
36
Q

Most interactive part of PACS

A
