Transcript of PACS and DICOM

A Journey into the PACS & DICOM System What is PACS? Picture Archive and Communication System
Invented in the 1980's
Now replacing x-ray films with digital images
Links imaging study reports with the corresponding study for easier imaging capability Purpose of PACS Hard copy replacement
Remote access
Electronic image integration platform
Radiology workflow management Systems that use PACS Ultrasound
Direct Radiography
Computed Radiography
And more... What is DICOM? Digital Imaging and Communications in Medicine
Invented in 1985
Standard for handling, storing, printing and transmitting information in medical imaging
Includes file formatting and a network communications protocol General Application Areas Network image management
Network image interpretation management
Network print management
Imaging procedure management
Off-line storage media management How they work together Query & Retrieval (Q/R) Developed to automatically identify and recover missing images Study (Lou, Hoogstrate & Huang) DICOM-based PACS acquisition setup was implemented for 3 months
34% of studies weren't automatically input into the PACS acquisition computer
Due to the transfer mode and/or transfer destination was changed and not reset
DICOM Q/R was then implemented in the same PACS acquisition database for 2 months
Statistical studies show that 259 studies were automatically acquired and not a single one was missing Benefits of Q/R in DICOM & PACS No missing images
Sequenced in correct order
Retain images from different locations
