Methods and apparatus for automatic image noise reduction

摘要: The present invention, in one form, is a system which, embodiment, adjusts the x-ray source current to reduce image noise better accommodate different scanning parameters. Specifically, adjusted as function of slice thickness, scan rotation time, collimation mode, table speed, and filtration mode. Particularly, stored CT computer determine an adjustment factor so that appropriate supplied for determined After adjusting current, object scanned.
