Lesson 3 FINALS Flashcards
it simply means how a process is done step by step
Workflow
in radiology the term ___ has always been used to described how an examination is completed
workflow
the movement of patients, images, and information throughout the imaging department and healthcare estripeses
Workflow
combing with digital images with __ the network eliminates even more steps in medical imaging workflow and enhances efficiency
Picture Archiving and Communication System
(PACS)
an image management system that acquires, stores, forwards, manipulates, and displays images
PACS
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
when fully implemented, allows not only the acquisition but also the interpretation and storage of each medical image
PACS
the projected efficiencies of time and cost are enormous
PACS
improves image, interpretation, processing, viewing, storage and recall
PACS
until the mids 1990s essentially all medical images were presented to the radiologist on film
Hard Copy
the image was interpreted from the film, which was positioned on a _____
lighted viewbox
viewing is performed on a cathode ray tube (CRT) or Liquid Crystal Device (LCD)
Soft Copy
Note: LCDs are superior to CRT displays
OK
What are the 4 Principle Components of PACS
- The image acquisition system
- The display system
- The network
- The storage system
imaging devices that acquire images from the patient such as CT scan, MRI, Ultrasounds, Xray machines and etc
Image Acquisition
machines are handled with dedicated computers too for viewing the raw images
Images 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
The Network
is described the manner in which computer can be connected to interact with one another
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 todays hospital 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 Communication in Medicine
(DICOM)
ultrasound, computed tomography, magnetic resonance imaging, and nuclear medicine have been digital for many years and have been taking advantages of PACS for longer than general radiography has
Imaging Acquisition
any computer that a health care worker uses to view a digital image
Displays Workstations
it is the most interactive part of a PACS, and these workstation are used inside and outside of radiology
Display Workstations
receives images from the archive or from the various radiology modalities and presents them for viewing
Display Workstations
has PACS application software that allows the user to perform minor image manipulation techniques to optimize the image being viewed
Display Workstations
file room of the PACS
Archive Servers
it is composed of a databases server or image manager, short-term and long-term storage, and a computer that controls the PACS workflow, known as
workflow manager
it is composed of a databases server or image manager, short-term and long-term storage, and a computer that controls the PACS workflow, known as workflow manager
Archive Servers
the central part of the PACS and houses all of the historic data along with the current data being geberated
Archive Servers
in many institutions, the archives servers as the central hub that receives all images before they are released to the radiologist for interpretation
Archive Servers
is the most interactive part of a PACS, consisting of a monitor and a computer with a mouse and keyboard
Display Workstation
radiography uses large multiviewer lightboxes to display the images
Conventional film / Screen
is one of the most important elements of a PACS display station
Monitor
is the most popular type of monitor used in a radiology department
(LCD) Liquid Crystal Display
used by a radiologist when making a primary diagnosis
Radiologist Reading Stations
has the highest quality hardware, including the best monitor
Radiologist Reading Stations
there is generally access to a nearby RIS, with a dictation system near or even connected to the PACS station
Radiologist Reading Station
step-down model of the radiologist reading station
physician review stations
many vendors use the same level of software but may eliminate some of the more advanced functions
Physician Review Stations
may be used to look up examinations for a physician or to print copies of images for the patient to take to an outside physician
File Room / Image Management Stations
can be viewed on any PC and generally comes with easy-to-use software burned onto it with the images
CD of Images
the term ___ can be defined as a place where records or documents are preserved
archive
in PACS the ___ serves as the new file room and warehouse for all DICOM imaging modalities
electronic archive
contains the master database of everything that is in the archive
image manager
it controls the receipt, retrieval, and distribution of the images it stores and also
controls all the DICOM processes running within the archive
Image Manager
is also the PACS component that interfaces with the radiology information system RIS and the hospital information system HIS
Image Manager
consists of the physical storage device of the archive system
image storage or archive server
