ABSTRACT:
A method for regulating a scan dosage includes generating an initial technique command based on default patient size or the previous exposure and on completion of exposure, receiving the actual technique signal. A target entrance dose signal is determined based a default patient size, and tube current is regulated in response to the target entrance dose signal and dose feedback. Image brightness is independently controlled in response to the target entrance dose and average image brightness. An object size is estimated based on the actual technique signal and an image brightness feedback. An optimized generator technique is defined based on estimated object size to achieve a target image quality for the user selected contrast material.
