SYSTEMS AND METHODS FOR SELECTING BOWTIE FILTER CONFIGURATION

An imaging system is provided including a selectable pre-object filter module, a detector, and a processing unit. The selectable pre-object filter module is configured to absorb radiation from the X-ray source to control distribution of X-rays passed to an object to be imaged. The selectable pre-obj...

More Information
Summary:An imaging system is provided including a selectable pre-object filter module, a detector, and a processing unit. The selectable pre-object filter module is configured to absorb radiation from the X-ray source to control distribution of X-rays passed to an object to be imaged. The selectable pre-object filter module has plural pre-object filter configurations providing corresponding X-ray distributions, and is selectable between the plural configurations to provide a selected pre-object filter configuration for a scan of the object. The detector is configured to receive X-rays that have passed through the object. The processing unit is operably coupled to the selectable pre-object filter module and the detector, and is configured to identify an anatomy to be imaged, determine a corresponding image quality and radiation dose for each of the plural pre-object filter configurations; and select the selected pre-object filter configuration based upon the determined corresponding image qualities and radiation doses.
