MODULE 6: PACS Components Flashcards
Six Main Components of PACS System
- Image Acquisition
- Communication Network
- Patient Data
- Display of images
- Recordings Archive
- Web Server
Requires the existence of medical devices with the appropriate interface of PACS
Image Acquisition
international standard for defining the mode of transmission of medical information and images that provides interoperability between different devices
DICOM
Simple and easy-to-use Windows application for converting medical image files between different image form
Medical Image Converter
can export whatever DICOM file you have to BMP, GIF, JPG, TIF, or WMF. If there is a series of images, it also supports saving them to a video file in the WMV or AVI format.
MicroDicom program
Transmits images and attached data
Communication Network
- is contained in HIS, RIS and PACS
- PACS used to view the images and The RIS used to view the result and the patient’s Information
Patient Data
-is the standard that enables the integration of HIS and RIS to the PACS System.
- Are a set of international standards used to transfer and share data between various healthcare providers.
- Aims to make sharing data easy which reduces the administrative burden on providers and staff while improving care delivery
HL7 - Health Level Seven, (7th OSI layer protocol)
What does OSI stand for?
Open System Interconnection
a shared boundary across which 2 or more separate components of a computer system that exchange information
Interface
- Done via personal computer in the office
- The qualities of personal computers in the office are reflected in the monitor’s physical characteristics.
Display of Images
Computers need to have an _____________ interface with the possibility to adjust image contrast, zoom and move images and display data of the patient
interactive user
A system for archiving recordings should be centralized (under a single authority), with support for DICOM and HL7 standards
Recordings’ Archive
Application that resides on a Web server should provide adequate access and display of data to employees in medical institutions and distant users.
Web server
Radiology Department Effectiveness
Less:
- exam time & effort
- inefficiency and error
- diagnostic uncertainty
- patient risk
- exam inaccuracy
- IT footprint/ support
Radiology Department Effectiveness
Less:
- exam time & effort
- inefficiency & error
- diagnostic uncertainty
- patient risk
- exam inaccuracy
- IT footprint/ support
- Standard for handling, storing, printing and transmission of information in medicine
- A set of rules that allows the exchange of medical images and information between computers and hospitals.
- Establishes a common language that enables the usage of images and information, made on one type of manufacturers’ equipment, in digital systems of other
DICOM
______ provide storage and convenient access to medical images such as ultrasounds, MRIs, CTs, and X-rays.
PACS
_______ consists of files, definitions, and network protocol communication. Files in this format are most likely saved with either a .dcm or .dcm30 (DICOM 3.0) file extension, but some may not have an extension at all
DICOM
The Basic Functions of DICOM
- Communication and sharing of digital medical images, regardless of the manufacturer; to enable PACS to become a part of HIS, RIS, and other information systems;
- To ensure that the database of medical images become available irrespective of browser distance;
- To enable the functioning of teleradiograph
DICOM disadvantages arise in:
- the database and image processing;
- Simultaneous display of multiple images on the monitor when the quality of individual images is decreased or certain segments are cut off;
- Appearance of false coloring which appears in the adjacent gray level, false coloring in contrasting colors, etc.
Form of medical information system, which requires the use of telecommunications systems the form of:
1. Satellite
2. Internet
3. Mobile phones
4. Computer
Teleradiology
Searching For data transfer, teleradiology uses the

The development of mobile radiology is linked to
Marie Sklowdoska Curie
During _____, Marie Curie left her Lab behind, inventing a mobile x-ray unit that could travel to the battlefront. (Little Curie; trained 150 women to operate it)
WWI
The first diagnostic radiology app; Mobile device app viewing in radiology
Mobile MIM, 2011
The relevant features of mobile phones for mobile radiology in teleradiology are:
- 3 inches wide screens
- light from 250 cdl
- RAM memory of 256 Mb
- 800 MHz processor
- mobile internet that supports HTML5 standard & JavaScript
