6. PACS Archiving & Peripherals Flashcards
PACS System 6 Main Components
- 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 such as: CT (Computed Tomography) MRI (Magnetic Resonance Imaging) Digital X-ray Machine
Image Acquisition
international standard for defining the mode of transmission of medical information and images that provides interoperability between different devices
DICOM
the ability of computer systems or software to exchange and make use of information.
Interoperability
The development of mobile radiology is linked to
Marie Sklodowska Curie
Origin of file
Metadata
DICOM is developed by:
ACR – American College of Radiology
NEMA – National Electrical Manufacturers Association

DICOM
Digital Imaging and Communications in Medicine
Simple and easy-to-use Windows application for converting medical image files between different image formats
Medical Image Converter
can export whatever DICOM file you have to BMP, GIF, JPG, PNG, TIF, or WMF
if there’s 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
Ex. Name of the patient, Date of birth, etc.
Communication Network
is the standard that enables the interface of HIS and RIS
HL7 (Health Level Seven, 7th OSI layer protocol)
is done via personal computer in the office
Display of Images
A system for archiving recordings should be centralized, with support for DICOM and HL7 standards
Recordings’ Archive
Implementation of PACS
is reflected in:
- Saving space and time for archiving x-ray images
- Search for educational purposes
- X-ray records are stored on computer disks in electronic form
- Significant material saving
- There is no need for buying X-ray films because x-ray images are moved on compact disks (CD) whose price is lower.
- Improved x-ray image quality and speed of diagnostic radiology;
- Possibility to view images from remote locations;
- Better utilization of human resources;
- Possibility to networking computers of one or more health facilities;
- Modernization of work;
- Reduction in service costs and material consumption
Standard for handling, storing, printing and transmission of information in medicine
DICOM
A set of rules that allows the exchange of medical images and information between computers and hospitals
DICOM
Establishes a common language that enables the usage of images and information, made on one type of manufacturers’ equipment, in digital systems of other manufacturers
DICOM
It should be noted that _____ is not only a file format; it is directly related to the PACS
DICOM
consists of files, definition and network protocol communication
DICOM
DICOM Files are most likely saved with a ______ file extension, but some may not have an extension at all
.dcm or .dcm30
DICOM Disadvantages
arise in:
- Searching 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.
