RIS final review questions and answers, Exams of Computer Science
What is a high-end, expensive client computer - ANSWERa heavy iron
workstation
What kind of personnel only occasionally require access to an image and
don't typically make any management decisions based on an image -
ANSWERnon-critical users
What is an HL7 standard protocol that enables different applications to be
synchronized and share context. Can be used to achieve ''single-logon'' of
multiple applications. Prevents the user from having to retype information
when moving between information systems. - ANSWERCCOW (clinical context
object workgroup)
What kind of users frequently make patient management decisions based on
their interpretation of the image and require full diagnostic quality images -
ANSWERimage-intensive users
What does full fidelity images refer to as - ANSWERmaximum diagnostic
quality
What can be used due to the highly predictable nature of radiology workflow
to speed up workflow - ANSWERauto-routing and prefetching (ex; auto-route
the abdominal exams to the abdominal reading room workstations and
,prefetch the relevant priors to the same abdominal reading room
workstation)
What is the difference between autorouting and prefetching -
ANSWERautorouting is used to send current 'wet' films to remote
destinations based on predefined ruled and prefetching is the automatic
delivery of image datasets from the archive that can be used for comparison
before it is requested by the user
What describes being able to provide high performance ubiquitous
distribution of images throughout the entire enterprise (and beyond) -
ANSWERscalability
What uses few resources on the local machine, instead relying on computing
power from centralized servers - ANSWERthin web clients (thick clients rely
more on the local machine)
What is a group of popular web methods used to create interactive web
browser-based applications - ANSWERAJAX (asynchronous JavaScript and
XML)
What defines a DICOM standard to access DICOM objects via the web -
ANSWERWADO
What reduces size of image data by applying relatively ''less bits/ element'' in
the subregion of the image dataspace that contains less ''useful information.''
- ANSWERLossy image compression
,What is an example of a streaming approach to web-based image delivery -
ANSWERdynamic transfer syntax (DTS)-this does not require lossy
compression
In what model do enterprise users frequently require not only current/
recent images but also relevant prior exams - ANSWERpersistence model
What is image storage (separate from the main PACS archive) where image
studies are stored for only a limited (not permanent) amount of time. -
ANSWERa limited persistence cache
What can be reconstructed using multiplanar reconstruction in any plane
using the initial data set - ANSWERan isotropic data set
What provides the ability to efficiently reconcile imported image datasets by
matching external identifiers with local identifiers - ANSWERIHE Integration
Profile for Import Reconciliation Workflow (IRWF)
What guarantees that any image CD/ DVD will have a DICOMDIR and DICOM
part 10 image files (in addition to any ''proprietary stuff'') - ANSWERIHE
Integration Profile for Portable Data for Imaging (PDI)
What are common components of an enterprise image distribution
infrastructure - ANSWERd
What are some of the fundamental functional requirements of enterprise
image distribution - ANSWERflexibility, performance, scalability, cost-
effectiveness, integration to EHR, security
, Which is NOT a common component of enterprise image distribution?
a. On-demand archive
b. EHR integration
c. Auto-routing
d. Web server
e. Citrix - ANSWERc
Which of the following can be used to deliver images to the enterprise?
a. WADO
b. Image compression
c. Just in time data delivery
d. All of the above
e. None of the above - ANSWERd
Describe the characteristics of an ''image-intensive user' - ANSWERFrequently
make patient management decisions based on their interpretation of the
image; frequently demand and require full-fidelity/diagnosticquality images;
also demand rapid (''near real time'') delivery of images, including relevant
priors; usually still constrained by existing network and personal computer
infrastructure
Which of the following are examples of ''image-intensive users?''
a. Pulmonologist
b. Neurologists
c. Hospitalists
d. All of the above
