DICOM stands for Digital Imaging and COmmunication in Medicine. The DICOM standard addresses the basic connectivity between different imaging devices, and also the workflow in a medical imaging department. The DICOM standard was created by the National Electrical Manufacturers Association (NEMA), and it also addresses distribution and viewing of medical images. The standard comprises of 18 parts, and is freely available at the NEMA website: http://medical.nema.org. Within the innards of the standard is also contained a detailed specification of the file format for images. The latest version of the document is as of 2008. In this article, we present a viewer for DICOM images. We also demonstrate the way to modify the brightness and contrast of the displayed image through Window Level.
