Carestream utilizes INDUSTREX image viewing software to navigate digital images. Image processing is a mathematical algorithm that can enhance the detection of discontinuities. Carestream NDT image processing came from technology developed for medical imaging by the Kodak Health Imaging Research Labs. The medical radiology image processing was adapted to industrial radiography over the last two decades and has been optimized for the NDT application. How image processing works, and best practices will be presented as part of this paper.
