Major advances in imaging, including MRI, MRI and ultrasound, have been major
drivers in this development. The health system needed a way to organize and
save files and images and preserve them.

 

Electronic picture archiving and communication systems (PACS)
have been developed in an try and offer least expensive storage, fast retrieval
of photos, get entry to pictures received with more than one modalities, and
simultaneous access at more than one sites. Enter to a PACS may also come from
virtual or analog assets (when the latter have been digitized). A PACS is
composed mainly of an image acquisition device (an electronic gateway to the
machine), data management system (a specialised computer device that controls
the glide of records on the community), image storage devices (each brief- and
lengthy-time period records), transmission network (which serves local or
extensive areas), display stations (which include a computer, textual content
screen, photo monitors, and a person interface), and devices to produce
hard-copy images (currently, a multiformat or laser camera). 1

 

 

 

 

 

PACS
popularity

The growing adoption of health information technology (health
IT) and the increasing use of diagnostic imaging are stimulating the market for
PACS technologies. One market research study estimated the size of the global
PACS market at $2.9 billion in 2016, and it projected the market to grow by
about 5.9% a year to $4.1 billion by 2021.

 

Healthcare providers putting in or replacing a PACS may do so
due to workflow inefficiencies or a want for a PACS that permits them to view
and save all pictures within one device. A PACS, much like other healthcare IT
systems, is problem to technological and regulatory standards, that may change
and force care carriers to take into account an upgrade. 2

 

Importance & Limitations

 

Importance:

A patient can also go through a battery of radiological
investigations at separate places, which needs to be accessed through more than
one radiologists and more than one treating physicians in distinct places
(sometimes across the globe). A system for fast transfer of pictures, at the
same time as maintaining the original quality is a essential, albeit complex
technological need.

additionally, hard-copy films are difficult to store and
archive, and the quality deteriorates over time. 3

 

 

Limitations:

Capital cost was a main challenge in the early years however
entry of multiple companies into the market, as well as the geometric increase
in processing energy and digital storage has appreciably delivered costs down.

The main limitation of PACS or teleradiology devices, is the quality of images,
which can be compromised by suboptimal resolution show monitors at different
locations. additionally, any technical failure, and improper back-up storage
may also hamper the records retrieval as well as massive data loss may also
happen. 3

 

 

 

 

 

Interfaces to Other Systems

To function properly, the image management system must
interface with other patient care management systems. These include but need
not be limited to a radiology information system (RlS) and a hospital
information system (HIS). The goals of interfacing the PACS to an RIS and an
HIS are to maintain data integrity across the global system and to optimize the
performance of each component system by using only the specific data needed for
each. The RIS provides basic patient histories, reporting of results, and
collection of data for department management. The HIS manages the demographic
standards and distributes patient care information throughout the medical
center. 1
