3. What is PACS?
 Picture Archival and Communication System
 Used in Radiology Dept. of Hospitals
 Provides Workflow to store and retrieve Radiology Images
 Radiology Images can be:
 Digital Radioscopy (X Ray)
 CT Scan
 MRI Scan
 PET (Positron Emission Tonography)
 Endoscopy
 Mammograms
 Ultrasound
 Doppler
 Etc.
 Uses DICOM (Digital Imaging and Communications in Medicine)

4. Evolution of PACS
 DICOM gained popularity before ~20 years
 Film used due to:
 No standard
 Vendors trying to play monopoly with their Imaging devices and
PACS Software
 PACS gained popularity from the year 2000
