DICOM AND PACS
Presentation outline
Introduction
Components and architecture of PACS
Application of PACS
Introduction
• The growing popularity of digital sensors in medical science
increases digital data produced in medical practices.
• PACS provides an efficient handling method for medical
imaging.
• It is a medical imaging technology which provides economical
storage and convenient access to image from multiple
modalities.
Components and architecture of PACS
Image acquisition component
PACS controller
Database server and archiving system
Workstations
Network
Communication Protocol
Image Acquisition Component
PACS Controller
The PACS controller is the main engine of the PACS
PACS Controller performs:
Automatically retrieve images, optimization of
pictures ,image data compression,etc
Database Server and Archiving System
Short term archive
•
Images from last recent studies and
examination are firstly stored there
Long term archive
• long-term archival of image data
Kintronics
NSM DVD
Jukeboxes
Workstations
A workstation is a computer with connected monitors to display the
information's of the PACS.
The workstation computers are running software for
communication, database access, displaying the images, resource
management and for processing.

Working with DICOM files
• MATLAB support the following support for working with files
in the DICOM format:
• Reading any file that complies with the DICOM standard.
• Writing the different types of DICOM files
– Magnetic resonance
– Computed Tomography,etc
Working with DICOM files
• Reading and viewing Image data from a DICOM file
I = dicomread('CT-MONO2-16-ankle.dcm');
>> imshow(I,'DisplayRange',[])

Future Trends and development
A
PACS are going to provide further technologies for teleradiology
Newer technologies for low –bandwidth data transfer are currently
enabling to view image stream on mobile devices
