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
