PACS
• Picture Archiving and Communication System is a
medical imaging technology which provides
 Economical storage.
 Convenient access to images from multiple
modalities.
• Electronic images and reports are transmitted
digitally via PACS.
PACS
• The universal format for
PACS image storage and
transfer is DICOM
(Digital Imaging and
Communications in
Medicine).
NEED OF PACS
• To obtain images in digital format.
• Images can be viewed offsite.
• Interpretation of data is possible immediately.
• Data storage is done digitally. Hence no file room is
needed.
USE OF PACS
• Hard copy replacement
• Remote access
• Electronic image integration platform
• Radiology Workflow Management

Interpretation Workstations
1. Diagnostic:
• Primary interpretation of Exam
• Highest in resolution and brightness
• Highest level of functionality
2. Review:
• Direct access to the image along with radiology
report
• Advent of web based workstation
Reengineering workflow
• Workflow- The steps that employees perform as they
are getting their work done, and the relationships
between those steps.
• Reengineering workflow-Analysis and breakdown of
individual steps that occur in the performance of a
multistep task.
• e.g. acquisition and interpretation of a radiograph
Dual mission
• Highest quality of patient care Well informed selection of imaging techniques
 Skilled interpretation
 Timely and clear communication
 Efficient use of available personnel
• Maximize income or minimize loss
Analyzing workflow
 Personnel perspective Clerical
 Radiologic technologists
 Queuing perspective Arrival
 Service
 Radiologist’s perspective Work lists
 Access
 Initial display
What is needed
•
•
•
•
•
Better coordination with other services.
Intelligent ordering and scheduling
Electronic study protocol selection
Electronic positive patient ID
Integration og modalities with RIS /PACS
Advanced integration approaches
• IHE (DICOM/HL7)
• Distributed object tools
 CORBA
 JAVA
 ActiveX
• Web services
 Service oriented Architecture
