DICOM AND PACS PACS provides efficient storage and access to medical images from multiple modalities. It has several key components: an image acquisition component which collects images, a PACS controller which manages images, a database server for storage, and workstations where images can be viewed. Images are stored both short term and long term. Communication between components uses standards like DICOM and HL7. Current PACS products provide features like remote access and workflow management. MATLAB can also be used to work with DICOM files, including reading, writing, and viewing medical images.

3. • 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.

6. 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

7. 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

8. 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.

13. Application of PACS
A
• Hard copy replacement
• Remote access
• Electronic image integration platform
• Radiology workflow management

14. 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

15. Working with DICOM files
• Reading and viewing Image data from a DICOM file
I = dicomread('CT-MONO2-16-ankle.dcm');
>> imshow(I,'DisplayRange',[])

17. Working with DICOM files
• Reading Metadata from A DICOM file

20. 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
