A picture archiving and communication system (PACS) is a computerized
means of replacing the roles of conventional radiological film as images are
acquired, stored, transmitted, and displayed digitally.
PACS aids in viewing, storing and retrieving, communication and managing
of medical digital images and related information. The related information
could be patient demographic information, contain diagnostic reports, or
The managing aspect facilitates the workflow of an imaging department
such as organizing studies, presenting them in a consistent manner in the
form of work lists, and keeping track of study status.
The replacement of conventional x-ray film is not the only role of PACS.
The main benefits that PACS offers are as following:
PACS can solve the issue of images loss, stolen, or misfiled.
Two physicians will be able to view same image at different sites.
Allows full range of tools for better visualization of image.
Economically efficient as it prevent expenditure on films, film packets, fill
processing chemicals, staff salary, and film filing clerks.
The biggest advantage is huge increase in efficiency of data management.
Before installing any PACS its disadvantages should be outlined first. Some
of the disadvantages include:
It is not a new technology but still has not been deployed at various health
The financial cost may be huge, preventing hospitals to install it.
PACS systems utilize large amounts of bandwidth on a system, can "crash"
even a very strong network or HCIS.
Strong internet technology needed to handle PACS traffic efficiently.
To read PACS report high resolution monitors are needed and they are too
Choosing the wrong vendor would be more costly than anything.
The syngo.via 3D routine and advanced reading solution is efficient, by
saving valuable time, helps physician to concentrate on their core task.
It is flexible, as modular licensing models are available; along with this
users can customize applications and layout.
These images are accessible through mobile devices so physician can view
them on their mobile phones and can also share them with colleagues. It
also makes workflow flexible.
Features and Benefits
Accelerated radiological workflows.
Save valuable time.
Access and reading of cases are faster and easier with automated updates
and pre-fetching of prior examinations.
Guide the workflow with automatically pre-processing images, compile up
findings and support quantitative reading functions.
GE CENTRICITY PACS
Centricity PACS presents a ascertained, scalable imaging IT platform
designed to optimize radiologist productivity, enhance physician
satisfaction, and interoperate with existing departmental (RIS) and
enterprise (EMR) systems.
With the innovations like single DB Rad/Card, RIS/PACS, advanced
visualization, web-based clients, EMR integration, DR/BC and high
availability, and most recently, mobile access on an Apple or Android
enabled device, Centricity PACS is able to overcome the challenges and
meet the challenges of healthcare institutions.
Features and Benefits
Helps increased productivity of radiologists and physicians.
Enhanced clinical depth with specialized tools.
Greater radiologist collaboration with web-based and mobile-based clients
for Apple and Android devices.
Better patient experience in ICU, ED and clinics with mobile access to
images and reports on Apple or Android devices.
Adherence to industry standards such as DICOM, HL-7, IHE and XDS.
Support for IT optimization objectives with VMWare.
Access to advanced imaging, communication, collaboration tools and
exceptional interoperability with department and enterprise systems.
Protection for databases and stored records from damage with disaster
recovery options including offsite storage (ASP) and database replication.
24/7 support from expert GE Healthcare teams before, during, and after you
implement your Centricity PACS solution.
Raster iPACS is completely amenable to DICOM standards. The software
works on a high performance multi-core scalable servers. As it runs on
Linux it assures stability while functioning. RAID hard drive stored all data
ensuring maximum data integrity.
Raster iPACS is OSS that is easily downloadable from Raster website.
Raster provides support to user whenever needed.
Open Source Clinical Image and
Object Management (DCM4CHEE)
DCM4CHEE is a DICOM archive par excellence. It is supporting PACS
and Image repositories for 10 years, and itself a pioneer in the world of
DICOM archives. Considering both financial and philosophical aspect it is
Developed on JBOSS (Java on any supported platform – Linux, Unix,
Compliance to DICOM, HL7 and IHE.
Siemens Syngo :
This is mainly used for CT and MRI studies.
Initially only syngo was used at JNPATC.
As Syngo used different system (silver light supported), and AIIMS uses
thinkline system, it was difficult to access syngo.
Radiology department also faced some difficulty while working on it.
This PACS also help radiology doctors to add finding on it, which is not
available to any other PACS.
GE Centricity :
It is currently being used for CT, MRI, X-Ray and US studies.
GE centricity is widely used PACS in AIIMS.
It is easier to use as progression to next step is simpler to understand.
Not much practice is needed to be master in GE centricity.
There is no storage issue with it as it can be increased according to
Raster iPACS :
It is open source PACS.
The motive to install this is just it is a free OSS, do not need much
Whenever support is needed, organization provides assistance.
Patient information can be merged to prevent duplication of same patient
It also provides an option to add patient directly in PACS.
Patient images can be exported to other destinations.
Patient attributes can also be edited.
It enables viewing images in HTML, PDF and waveform format.
DCM4CHEE allows offline storage too.
