WORKFLOW IN Radiology Flashcards
It simply means how a process is done, step by step.
Workflow
an Image Management system that acquires , stores,
forwards, manipulates and displays images.
- Digital medical images are stored on a medium that
allows quick access until the examination results are
reviewed by a radiologist or other physician.
PACS ( PICTURE ARCHIVING and COMMUNICATION SYSTEM)
Until the mid 1990s, essentially all medical images were _____ that is, the image were presented to the radiologist on
film. The image was interpreted from the film, which was
positioned on a lighted viewbox.
Hard copy
improves image, interpretation, processing,
viewing , storage and recall.
Pacs
viewing is
performed on a cathode ray tube (CRT) or Liquid Crystal Device (LCD).
Note: LCDs are superior to CRT displays
Soft copy
4 Principle Components of PACS
- The image acquisition system
- The display sytem
- The network
- The storage system
Imaging devices that acquire images from the patient such as CT scan, MRI, Ultrasound, Xray machines and etc. Machines are handled with dedicated computers too for viewing the raw
images.
Image Acquisition
Computer used to view a digital image.
The display system
This requires that each workstation must interact with each other imaging system and central computer.
is described the manner in which computer can be connected to interact with one another.
The network
The amount of storage necessary depends on the modality or modalities served by the PACS and on the workload.
The storage system
is becoming more
commonplace in today’s
hospitals because hospital
administrators have come to
see the necessity of having
such a system to serve
physicians and patients even though it is expensive.
picture archiving and
communication system
(PACS
is a universally accepted
standard for exchanging medical
images among the modality,
viewing stations, and the archive
Digital imaging and
communications in medicine
(DICOM)
Ultrasound, computed
tomography (CT), magnetic
resonance imaging (MRI), and
nuclear medicine have been
digital for many years and have
been taking advantage of PACS
far longer than general
radiography has
Image Acquisition
Any computer that a health care
worker uses to view a digital image.
It is the most interactive part of a
PACS, and these workstations are
used inside and outside of radiology.
Display Workstation
File room of the PACS.
The central part of the PACS and houses
all of the historic data along with the
current data being generated.
Archive Servers
