Question | Answer |
---|---|
What is a LAN and what are two benefits of a LAN | Local Area Network; least expensive and fastest because of less components |
What is a WAN and what does it use to link computers? | Wide Area Network; it uses telephone lines and satellites to link computers |
What is a computer network system? | 2 or more objects sharing resources and information |
What is a Server? | Centralized computer used for storage and retrieval of all information of computers on the network |
True/False: Servers have multiple users? | True |
The Server is the basis/command center for what? | PACS |
True/False: Any computer can access any image/s for the patient from the server? | True |
What are standards of communication? | required to establish compatibility and communication among all types of hardware/software |
Current standards of communication include what? | DICOM and HL7 |
What does DICOM stand for? | Digital Imaging and Communications in Medicine |
What does DICOM do? | communicate between PACS and other imaging modalities like CT, MRI, etc.. |
List 4 benefits of DICOM | 1- common networks for compatibility with hardware/ software 2- Specific contents of “header” and pixel structure for each modality for interoperability 3- hardware/software compatibility 4- communication between vendors/users for standards of use |
What does HL7 stand for and what is it? | Healthcare Level 7: Communication between the HIS and RIS. includes imaging, insurance data, pharmacy, labwork, etc.. |
What does HIS stand for and what is it? | Hospital Information System: hospital database that supplies worklist it contains all pt information like labs, prescriptions, orders, insurance info and scheduling of test |
What does RIS stand for and what is it? | Radiology Information System: Intranet used in radiology to store, manipulate and distribute pt data and images. Comprised of pt tracking, scheduling, reporting, image tracking |
What does EMR stand for and what is it? | Electronic Medical Record: Either part of HIS or on its own. Contains pts entire medical record. PACS has begun to interface with EMRs to allow more accessible images. |
What does PACS stand for and what is it? | Picture Archiving and Communicating System; its and electronic version of a film library |
List 4 principal components of PACS: | Acquisition, Display Workstation, Network and Storage System |
True/False: PACS has eliminated many steps required by the technologist once required with film significantly increasing workflow | True |
Name a few common PACS functions: | Navigation, hanging protocols, study navigation, window/level, Annotate, Flip/Rotate, Magnify, Measurements, image management functions |
Name 4 advanced functions of PACS: | 1- Multiplanar Reconstruction (MPR), 2- Maximum and Minimum Intensity Production (MIP and MinIP), 3- Volume Rendering Techniques (VRT), 4- Shaded Surface Display (SSD) |
Name 2 advance tech QC PACS Functions: | Stitching and Image Processing |
What is archive function? | long or short term storage of images, records or documents. Most common storage devices include: film digitizers, disks, tapes, CDs, DVDs |
