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
