Abstract
Systems and methods for correcting the image intensity of under-exposed regions of CR (computed radiography) images for mosaic composition. In one aspect, a method for generating a mosaic CR image comprises acquiring a set of CR images and processing each CR image to detect an under-exposed region in the CR image. If an under-exposed region is detected, the CR image is separated into an under-exposed region and normal exposure region. The image intensity of the under-exposed region is then adjusted to be substantially similar to, or as close as possible to, the image intensity of the normal exposure region of the CR image using nonlinear enhancement and/or linear transformation techniques. The intensity corrected CR images are then combined in a mosaic image.
