Abstract
A method and system for controlling a dynamic range of a medical diagnostic image provided by a medical diagnostic system. A target dynamic range is identified independent of a dynamic range of an original medical image. A presentation map is generated defining a relation between the dynamic range of the original medical image representative of a patient and the target dynamic range. A gray level-optical density model may define the relation between gray levels of the original medical image and target optical densities of the presentation map, the gray level-optical density model being calculated based on film characteristics, selected optical densities for anatomical structure or on a measured dynamic range. A presentation image is created having the target dynamic range based on a the presentation map and original medical image.
