2. 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.

3. PACS
The universal format for PACS image storage and transfer is DICOM (Digital Imaging and Communications in Medicine).

4. 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.

5. USE OF PACS Hard copy replacement Remote access
Electronic image integration platform
Radiology Workflow Management

12. Interpretation Workstations
Diagnostic:
Primary interpretation of Exam
Highest in resolution and brightness
Highest level of functionality
Review:
Direct access to the image along with radiology report
Advent of web based workstation

13. 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

14. 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

15. Analyzing workflow Personnel perspective- Clerical
Radiologic technologists
Queuing perspective-
Arrival
Service
Radiologist’s perspective-
Work lists
Access
Initial display

16. 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

17. Advanced integration approaches
IHE (DICOM/HL7)
Distributed object tools
CORBA
JAVA
ActiveX
Web services
Service oriented Architecture
