SYSTEM AND METHOD FOR GENERATING AN IMAGE OF A REGION OF INTEREST

摘要

The invention relates to an image generation system for generating an image of a region of interest. The image generation system comprises a measured data providing unit for providing measured data of the region of interest, a reconstruction unit (12) for reconstructing a first and a second image of the region of interest from the measured data using a first and a second reconstruction method, a noise determination unit (13) for determining first and second noise values for first and second image elements of the first and second image, and an image element combining unit (14) for combining corresponding first and second image elements into combined image elements forming a combined image based on the first and second noise values. By combining corresponding image elements of two differently reconstructed images based on determined noise values, a combined image of a region of interest can be generated with an improved quality.
