2. After reading this chapter the reader should be
able to:
• Describe the history behind digital radiology and
the creation of picture archiving and
communication systems
• Enumerate the benefits of digital radiology to
clinicians, patients and hospitals
• List the challenges facing the adoption of picture
archiving and communication systems
• Describe the difference between computed and
digital radiology
Learning Objectives
3. Definition of PACS
“PACS (picture archiving and
communication system) is an evolving
healthcare technology for the short and
long term storage, retrieval,
management, distribution and
presentation of medical images.”
4. PACS History
• The first reference to PACS occurred in 1979
when Dr Lemke in Berlin published an article
describing a similar concept
• The work on the radiology data standard
DICOM began in 1983 by a team lead by Dr
Steven Horii at the University of Pennsylvania
• Digital imaging appeared in the early 1970’s
by pioneers such as Dr. Sol Nudelman and Dr.
Paul Capp
• The University of Maryland hospital system
was the first to go “filmless” in 1999
• The father of PACS in the United States is felt
to be Andre Duerinckx MD PhD
5. PACS Basics
• Initially, hospitals purchased film digitizers so routine
x-rays could be converted to the digital format
• Now digital images go from the scanning device
directly into the PACS
• PACS usually has a central server that serves as the
image repository and multiple client computers linked
with a local or wide area network (LAN or WAN)
• Images are stored using the Digital Imaging and
Communications in Medicine (DICOM) standard
• PACS is made possible by faster processors, higher
capacity disk drives, higher resolution monitors, more
robust hospital information systems, better servers
and faster network speeds. PACS is also integrated
with voice recognition systems to expedite report
turnaround
6. PACS Basics …
• Input into PACS can also occur from a DICOM compliant
CD or DVD brought from another facility or teleradiology
site via satellite
• Most diagnostic monitors are still grayscale as they have
better resolution (3-5 megapixels), compared to color.
Newer “medical monitors” have 2,048 x 2,560 pixel
resolution
• PACS is now important for Cardiologist who perform image
producing procedures
• It is estimated that about 90% of large teaching hospitals
have PACS but usage by small community hospitals is far
lower
• PACS was initially associated with expensive work stations
($50K) using thick client technology. Now the trend is for
thin or smart clients that permit clinicians to access PACS
via a web browser from the office or home
7. PACS Key Components
• Digital acquisition devices: the devices that are the
sources of the images. Digital angiography, fluoroscopy
and mammography are the newcomers to PACS
• The Network: ties the PACS components together
• Database server: high speed and robust central
computer to process information
• Archival server: responsible for storing images. A
server enables short term (fast retrieval) and long term
(slower retrieval) storage
• Radiology Information system (RIS): system that
maintains patient demographics, scheduling, billing
information and interpretations
• Workstation or soft copy display: contains the
software and hardware to access the PACS. Replaces
the standard light box or view box
8.
9. Types of Digital Detectors
1) Computed radiography (CR): after x-ray exposure to
a special cassette, a laser reader scans the image and
converts it to a digital image. The image is erased on
the cassette so it can be used repeatedly
10. Types of Digital Detectors …
2) Digital radiography (DR): does not require an
intermediate step of laser scanning. It is important to
note that many facilities with digital systems or PACS
still print hard copies or have some non-digital
services. This could be due to physician resistance,
lack of resources or the fact that it has taken longer for
certain imaging services such as mammography to go
digital. Full PACS means that images are processed
from ultrasonography (US), magnetic resonance
imaging (MRI), positron emission tomography (PET),
computed tomography (CT) and routine radiography.
Mini-PACS, on the other hand, is more limited and
processes images from only one modality.
11. PACS advantages
• Replaces a standard x-ray film archive which
means a much smaller x-ray storage space. Space
can be converted into revenue generating services
and it reduces the need for file clerks
• Allows for remote viewing and reporting; to also
include teleradiology
• Accelerates the incorporation of medical images
into an electronic health record
• Images can be archived and transported on
portable media; USB drive and Apple’s iPhone
• Other specialties that generate images may join
PACS such as cardiologists, ophthalmologists,
gastroenterologists and dermatologists
12. PACS advantages …
• PACS can be web based and use “service oriented
architecture” such that each image has its own
URL. This would allow access to images from
multiple hospitals in a network
• Unlike conventional x-rays, digital films have a
zoom feature and can be manipulated in
innumerable ways
• Improves productivity by allowing multiple
clinicians to view the same image from different
locations
• Rapid retrieval of digital images for interpretation
and comparison with previous studies
• Radiologists can view an image back and forth like
a movie, known as “stack mode”
• Quicker reporting back to the requesting clinician
13. PACS disadvantages
• Cost, although innovations such as open source and
“rental PACS” are alternatives
• Integration with hospital and radiology information
systems and EHR
• Bandwidth limits
• Workstation limits
• Viewing digital images a little slower than routine x-ray
films
• Black and white computer monitors not as bright as
traditional x-ray view boxes. This may be an issue with
radiologists, but not the average physician
14. Key Points
• PACS is the logical result of digitizing x-rays,
developing better monitors and improving
medical information networks and electronic
health records
• PACS is well accepted by radiologists and
referring physicians because of the ease of
retrieval and the quality of the images
• PACS is a type of teleradiology, in that images
can be viewed remotely by multiple clinicians
on the same network
• Cost and integration are the only significant
barriers to the widespread adoption of PACS
