The Digital Imaging and Communication On Medicine(DICOM) standard is a high level
standard which encompasses many variables which extend their scope much beyond the
realm of information exchange and data handling. Suvarna has developed an innovative
DICOM solution which is very useful for managing the various requirements of Digital
Imaging within a hospital. Our HIMS system is designed to be closely integrated
with DICOM software to enhance the functionality of software in your hospital. Our
Hospital Information System is designed to provide you with the best value for money
and enhance your hospital effeciency. When these are paired with the DICOM software,
it offers a highly reliable combination of performance and cost effective management.
The DICOM standard defines the following aspects
- The data structures and formats to be used for medical image transmission and related
data
- Network based services which include image transmission, image archiving, printing
functions.
- Cross functional integration of the Image archive query system(PACS) and Radiology
Information System(RIS) for ensuring seamless data management and output.
An overview of the DICOM Data Structure
A DICOM image consists of various attributes of data elements. These attributes
hold various types of information about the patient which include the patient's
Name, Sex and Identification Number. The Attributes are also defined on the various
parameters which include device parameters, calibration metrics, image and media
information etc which are critical in enhancing the correct identification of various
medical conditions which exist for the patient. While these data elements have been
clearly defined in the DICOM standard which gives it enormous flexibility, the incompleteness
of information is a major drawback in the system operation and can cause severe
problems when data exchange is involved. Every DICOM software is designed to to
support and read these data structures and display them in a meaningful format.
DICOM Network Interface
The DICOM models work on the client and server based interface. Every exchange of
data requires the establishment of a connection between the client and server and
must have a clear definition of the various aspects of the interface functionality.
These aspects cover the following areas:
- Client Server Definition
- DICOM Service Types
- Data transmission formats
A data connection is established only when there are common agreements between both
the transmitter and receiver about the type of data transmission and the variables
involved. The Associated application entities then convert the files in a viewable
format which can be seen by the user. These files can be shared using a variety
of peripherals like cameras and printers which aid in the image distribution process.
The DICOM Communication Standard
The DICOM Communication standard is clearly established worldwide and clearly defines
the various aspects of communication protocols which are created within the DICOM
standard for smooth functioning of the standard.
This standard supports the DIMSE(DICOM Message Service Element) protocols which
enable the exchange of messages between layers. The DICOM Standard uses a TCP/IP
protocol which is used to communicate between various devices present in the network
at various points.
DICOM Standard Features
The DICOM standard is open ended, therefore various applications can be structured
around it. This has given the standard enormous amount of flexibility in providing
solutions for every type of operational requirement which may exist in the medical
field. Right from the stage of image capture to final tagging and processing, the
DICOM standard defines and delineates the various parameters which need to be included
in the DICOM modules or softwares.
The DICOM standard streamlines the various workflow aspects of the image capturing
storage and transmission system across various hospital networks. Equipment carrying
the DICOM standard are future proof and will work with any type of future DICOM
protocols which may exist. This compatibility is the key for every hospital to reduce
their costs of having an integrated image capture, storage and transmission system.
Advanced version of the standard now support the automated scheduling collection
and storage of various tasks within a hospital system. These ensure an updated patient
status scheduling, Imaging capture, Image storing and Procedural status of the various
images within the DICOM network.
Offline storage and capture are and essential element of the DICOM standard and
these enable the printing and distribution of DICOM images which have all the parameters
required for processing.
