E.g. in cardiac cone-beam CT, the source path is interrupted due to the fact that the projection data is gated. According to the present invention, a method is provided to obtain projection data corresponding to an uninterrupted source trajectory from such a gated data set. For this purpose, a motion compensation is applied. Advantageously, a complete data set may be determined allowing for an approximate or an exact reconstruction method to be applied to the completed data set without interruption of the image generation. |
