<p>PROBLEM TO BE SOLVED: To provide a system and a method for generating an image.SOLUTION: One system includes a processor. The processor is configured to receive a requested object field-of-view and determine if the object field-of-view is possible on the basis of constraints of an imaging system, wherein the constraints include dimensions of a detector panel and motion limits of a collimator assembly. When the object field-of-view is possible, the processor is configured to dynamically generate a set of collimator motor commands and reconstruction parameters on the basis of the object field-of-view, calibration parameters of the collimator assembly, and geometric calibration parameters of the imaging system. The processor is also configured to provide the set of collimator motor commands to the collimator assembly to position shutters of the collimator assembly so as to illuminate the object field-of-view.</p> |
