Abstract

Various methods and systems are provided for x-ray tube conditioning for a computed tomography imaging method. In one embodiment, a scout scan may be carried out prior to a diagnostic to warmup the x-ray tube to a desired temperature for the diagnostic scan. A scout scan parameter optimizing algorithm may be used to determine scout scan parameters based on a selected patient absorbed dose range and an amount of energy to be imparted to an x-ray tube during the scout scan preceding a diagnostic scan. By using a hardening filter in the path of the x-ray beam, radiation absorbed dose of the subject being scanned may be limited to the selected patient absorbed dose range.
