DICOM Viewer- A Complete Case Study

Digital Imaging and Communications in Medicine (DICOM) is the standard for managing, storing, printing, and transmitting information in medical imaging. It includes a file format definition and a network communications protocol.

DICOM viewing software assists radiology consultants and trainees to view and manipulate medical images (MRI scans or radiographs) on PC, Laptop or other devices.  In hospitals, this forms part of the Picture Archiving and Communication System (PACS), which doctors will be familiar with!

The National Electrical Manufacturers Association (NEMA) holds the copyright to the published standard which was developed by the DICOM Standards Committee, whose members are also partly members of NEMA. It is also known as NEMA standard PS3, and as ISO standard 12052:2017 “Health informatics — Digital imaging and communication in medicine (DICOM) including workflow and data management”.

DICOM Viewer includes:

  • Open and save medical images in DICOM format
  • Supported DICOM images – without compression and with RLE, JPEG Lossy, JPEG Lossless, JPEG2000 Lossy, JPEG2000 Lossless compressions
  • Structured Reports, MPEG-2 and MPEG-4 transfer syntaxes, Encapsulated PDF
  • Open images in common graphic formats(jpeg, bmp, png, gif, tiff)
  • Open DICOM directory files
  • Display patient list from DICOMDIR
  • Display images from different studies or examinations
  • Load DICOM images via drag & drop or double-click in DICOM viewer
  • Convert DICOM to JPEG, BMP, PNG, GIF, TIFF
  • Convert DICOM to WMV, AVI
  • Copy DICOM image to clipboard
  • Brightness/contrast control
  • Zooming and panning DICOM images
  • Medical image processing operation
  • Measurements and annotations
  • Displaying DICOM attributes of selected image
  • Suited for patient CD/DVD to show DICOM images without installation
  • CD/DVD DICOM Viewer
  • DICOM viewer run on Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1 and Windows 10
  • available for x86 and x64 platforms
  • DICOM viewer portable version

How DICOM Viewer works:

DICOM is mostly used for storing and transmitting medical images enabling the integration of medical imaging devices such as scanners, servers, workstations, printers, network hardware, and picture archiving and communication systems (PACS) from multiple manufacturers. It has been widely adopted by hospitals, and is making inroads into smaller applications like dentists’ and doctors’ offices.

DICOM files can be exchanged between two entities that are capable of receiving image and patient data in DICOM format. The different devices come with DICOM Conformance Statements which clearly state which DICOM classes they support, and the standard includes a file format definition and a network communications protocol that uses TCP/IP to communicate between systems.

The DICOM Viewer Standard

DICOM does not only define the image and data sets but also the transport layer protocol and other services. The whole standard is made up of 20 related but independent sections. For example the Data Dictionary that I mentioned in the previous section is one of these sections. Other sections define a fair few other services that machines can implement to carry out useful tasks. For example there are sections defining:

  • Managing imaging procedure
  • Printing images to digital media like DVDs
  • Confirming successful archiving of images
  • Saving image manipulations and annotations
  • Encrypting datasets
  • Removing patient identifying information from datasets
  • Organizing layouts of images for review
  • Reporting procedure status like completion of an imaging acquisition

Advantages of the DICOM Viewer

The standard has various advantages including:

  • Single network transactions will transfer both image and patient details
  • Enhanced patient safety (images and data kept together)
  • Consistent standard across multiple devices means better compatibility
  • Store rich acquisition and imaging protocol data
