Title: PACS Chapter 8


1
PACSChapter 8
  • Picture Archiving and Communication System

2
Anatomy of PACS
  • Figure 8-1
  • Digital acquisition
  • Display workstations
  • Storage devices
  • Electronic version of reading room and the file
    room

3
Digital imaging and communication in medicine
  • AKA DICOM
  • Each modality and PACS communicate via DICOM

4
3 fundamental parts of PACS
  • 1-Image acquisition
  • US, CT,MRI, Nuc Med and finally general
    radiography
  • Increased images per patient promoted the use of
    extra stations
  • Many work station gave way to full PACs systems

5
3 fundamental parts of PACS
  • 2 Display workstation
  • Receives images from archive or from various
    radiology modalities
  • PACs application software for image manipulation
    (minor to more complex techniques)

6
3 fundamental parts of PACS
  • Archive Servers
  • Electronic file room
  • Short term or long term storage
  • Controls the PACs workflow
  • Archive receives images before they go to
    radiologist
  • Why is this something the radiographer should be
    aware of?

7
COMPARE THE FILM BASED WORK FLOW TO WHAT YOU DO
NOW
8
PACS ARCHITECTURE
  • Client/server-based system
  • All images from all modalities go to a central
    archive server
  • Images are then sent to the reading room
  • Advantages?
  • Disadvantages?

9
PACS ARCHITECTURE
  • DISTRIBUTED SYSTEMS OR STAND ALONE
  • Images sent to a designated reading station.
  • MRI to one station, CT to another
  • Advantages?
  • Disadvantages?

10
PACS ARCHITECTURE
  • Web based system
  • Similar to client/serve application except the
    application software is web based
  • Advantages?
  • Disadvantages?

11
DISPLAY WORKSTATIONS
  • Number of monitors required by radiologists have
    reduced-why?
  • LCD to soon replace all CRT tubes-why?
  • CT viewed on a 1K
  • CR/DR viewed on 2K
  • Mammo 5K
  • Lets review resolution

12
Reading stations
  • Radiologist
  • Physician Review
  • Can read report next to images
  • Tech QC station
  • What can be done here?
  • What should be confirmed here?
  • What is RIS?

13
FILE ROOM/IMAGE MANAGEMENT STATIONS
  • For image management purposes
  • Look up examinations for other physicians
  • Correct demographics before sent to archive

14
FUNCTIONS
  • Navigation functions
  • Hanging protocols
  • Study Navigation
  • Image manipulation and enhancement functions
  • What are these?
  • ROI region of interest

15
Patient demographics can be modified at the QC
station, the reading station and the file room
station
  • Why are there so many places that one can modify
    patient info? Refer to figure 8-1

16
ADVANCED FUNCTIONS
  • Stitching
  • Image post processing
