Which DICOM service is used by a PACS to query a remote archive for available studies?
Answer: C-FIND
C-FIND is the DICOM query service that allows a SCU (Service Class User) to search a remote SCP (Service Class Provider) for matching studies, series, or instances.
In DICOM networking, what is the purpose of a Service Class Provider (SCP)?
Answer: It responds to service requests from a Service Class User
The SCP is the server-side role that receives and fulfills DICOM service requests, such as storing images (C-STORE SCP) or responding to queries (C-FIND SCP).
XDS (Cross-Enterprise Document Sharing) is an IHE profile designed to:
Answer: Share clinical documents including imaging reports across healthcare enterprises
IHE XDS enables sharing of clinical documents, including radiology reports and image references, across different healthcare organizations using a registry/repository model.
A hospital wants clinicians at an affiliated clinic to view PACS images through their EHR without installing separate viewer software. Which approach BEST supports this goal?
Answer: Implementing a web-based zero-footprint viewer using WADO-RS or DICOMweb
A zero-footprint web viewer using DICOMweb standards (WADO-RS, STOW-RS, QIDO-RS) delivers images through any browser without client software installation.
What does the acronym RIS stand for in the context of PACS integration?
Answer: Radiology Information System
RIS (Radiology Information System) manages scheduling, orders, results reporting, and billing in a radiology department, and is a key integration partner for PACS.
Which protocol is used to retrieve DICOM objects from a PACS using a RESTful HTTP-based approach?
Answer: WADO-RS (Web Access to DICOM Objects via RESTful Services)
WADO-RS is the RESTful DICOMweb service that allows HTTP GET requests to retrieve DICOM instances, series, or studies from a compliant PACS server.
When configuring a DICOM Application Entity (AE) title, which element uniquely identifies a DICOM device on the network?
Answer: AE Title combined with hostname/IP and port number
A DICOM node is identified by its AE Title plus the host address and port, forming a unique endpoint used in DICOM association negotiations.
