2. What is RIS
A radiology information system (RIS) is a networked software system
for managing medical imagery and associated data.

3. A RIS is especially useful for tracking radiology imaging orders and
billing information, and is often used in conjunction with PACS and
VNAs to manage image archives, record-keeping and billing.

4. Major Components of RIS
HIS (Hospital Information Systems)
PACS (Picture Archiving and Communication System),
VNA( Vendor Neutral Archival )
These are critical to efficient workflow to radiology practices.

5. RIS Basic Functions
Patient management
Scheduling
Patient tracking
Results reporting
Image tracking
Billing

7. What is PACS.?
PACS (picture archiving and communication system) is a healthcare
technology for the short- and long-term storage, retrieval,
management, distribution and presentation of medical images.

8. Major components of PACS
Imaging systems, such as magnetic resonance imaging (MRI), computed
axial tomography (CAT scan), and X-ray equipment.
A secure network for distribution and exchange of patient information.
Workstations or mobile devices for viewing, processing and interpreting
images.
Archives for storage and retrieval of images and related documentation
and reports

10. What is DICOM
The Digital Imaging and Communications in Medicine (DICOM)
Standard specifies a non-proprietary data interchange protocol, digital
image format, and file structure for biomedical images and image-
related information.

12. DICOM was originally developed by the National Electrical
Manufacturers Association (NEMA) and the American
College of Radiology for computerized axial tomography
(CAT) and magnetic resonance imaging (MRI) scan images.
It is now controlled by the DICOM Standards Committee and
supports a wide range of medical images across the fields of
radiology, cardiology, pathology and dentistry. DICOM uses
TCP/IP as the lower-layer transport protocol.

13. What is VNA..?
Vendor neutral archive (VNA), in a health information technology
context, is a medical imaging technology used by healthcare
professionals that stores images in a standard format and interface,
making medical imaging data accessible through different picture
archiving and communication systems (PACS).

14. Concepts of Neutrality

15. Few features of VNA
● Data Consolidation and Migration
● Information Lifecycle Management
● IT Simplification and Consolidation
● Non-DICOM content processing
● Dynamic tag morphing
One purpose of a VNA is to store information and serve it to multiple systems that may have different
requirements for its use and expectations for very specific characteristics of the DICOM attributes
and values stored in themThe concept of "dynamic tag morphing" as a solution to the problem of two
different systems expecting different values in the same attribute of DICOM.
