摘要 |
<p>The present invention relates to an image generation device for generating an image from measured data, wherein image quality is optimized for a region of interest and to an imaging system comprising this image generation device. The image generation device comprises a noise determination unit for determining a distribution of noise in a projection domain of the region of interest, and a dose control unit (32) for determining a dose profile for a radiation source (2) of said image generation device based on said determined distribution of noise by using a noise propagation algorithm. Thereby, signal-to-noise ratio of a reconstructed volume can be improved and is not sensitively dependent on a selected region of interest.</p> |
