Advances in camera technologies and reduced equipment costs have led to an increased interest in the application of thermal imaging in the medical elds . Medical infrared images are typically recorded and stored in digital form, and computerized image processing techniques have been used in acquiring and evaluating medical thermal images [13,26] and proved to be important tools for clinical diagnostics. Yet, these tools rely on the digital images to be in a certain format. Unfortunately, manufacturers of medical infrared cameras have their own proprietary image formats with little or no possibility of data interchange between suppliers. ere is therefore a need to develop a standardized format for storing and processing thermograms. In the rst part of this chapter, we will show that the DICOM (Digital Imaging and Communications in Medicine) medical imaging standard  can be adopted for this purpose.
