MY TOPIC• RADIOLOGY INFORMATION SYSTEM (RIS) AND

PACS

RIS• A computerized database used

by radiology departments to store, manipulate, and distribute patient radiological data and imagery.

THE SYSTEM

PACS (PICTURE ARCHIVING AND COMMUNICATION SYSTEM• A picture archiving and communication

system (PACS) is a medical imaging technology which provides economical storage and convenient access to images from multiple modalities (source machine types).

A BIT OF HISTORY• THE PRINCIPLES OF PACS WERE FIRST DISCUSSED AT

MEETINGS OF RADIOLOGISTS IN 1982.

• VARIOUS PEOPLE ARE CREDITED FOR THE COINAGE OF THE TERM PACS.

• CARDIOVASCULAR RADIOLOGIST Dr. ANDRE DUERRINCKX CLAIMS THAT HE HAD FIRST USED THE TERM IN 1981.

MODIFICATION OF THE IMAGE TO ENHANCE THE QUALITY

HELPS TO MAKE A BETTER DIAGNOSIS.

DATA RETRIEVAL CAN BE IN ANY FORMAT
