摘要
Summary processing component, which processes images based on iterative reconstruction algorithm with regularization algorithm and / or noise reduction method and a processing component (122) processes images based on an iterative reconstruction algorithm with the algorithm of Regularization and / or noise reduction.The processing component includes a determiner for the fixed point (224) that determines a fixed point of quality (216) between predetermined limits of lower quality and higher (226) based on a variable quality (228) indicative of a quality of image of interest.The processing component further includes a comparator (214) that compares, processing iteration, a metric of the quality of an image generated current to a fixed point of quality and generates a difference value indicative of a difference between the metric of quality and point The fixed quality.The processing component includes additionally an updater adjustment factor (220) that generates a regularization factor updated for a next processing step based on a current value (222) of the adjustment factor and at least in the metric of quality.In response to the value of the difference indicating that the metric of quality is out of a predetermined range relative to the fixed point of quality.
