Abstract:
1. A method for controlling a computed tomography (CT) system to perform an imaging process of a subject, the method comprising the steps of: selecting a scanning technique to be performed on a subject during an imaging process and having an associated at least one of an initial tube potential and an initial tube-current-time-product corresponding to a desired image quality level; selecting a noise constraint parameter related to at least one of a contrast to noise ratio (CNR) and an image quality index to be achieved with the imaging process; performing a scout scan using the CT system to determine a characteristic of the subject; adjusting at least one of the initial tube potential and the initial tube-current-time-product for the imaging process using information about the scanning technique, the characteristic of the subject, and the noise constraint parameter to create at least one of an adjusted tube potential and an adjusted tube-current-time-product for the imaging process; performing the imaging process using the at least one of the adjusted tube potential and the adjusted tube-current-time-product to collect medical imaging data; and reconstructing an image of the subject from the medical imaging data.
