Abstract
An image generating apparatus for image generation is provided. The image generating apparatus includes a movable detector for detecting nuclear radiation during a detection period and an evaluation system. The evaluation system includes an interface system for transmitting detector data to the evaluation system. The detector data include information about the detected radiation for image generation. The evaluation system further includes a data memory portion for storing the detector data. The evaluation system further includes a program memory portion with a program for repeatedly determining at least one quality value with respect to image generation during the detection period.
