A system and method for automatically adjusting parameters of an imaging machine are disclosed. The system comprises at least one sensor device to capture sensed characteristic information of a next person to be medically imaged. The system also includes a computer to receive the sensed characteristic information from the at least one sensor device and to generate adjustment data based on the sensed characteristic information. The system further includes a medical imaging machine to receive the adjustment data from the computer and to adjust at least one parameter of the imaging machine in response to the adjustment data.
