System of acquiring multi-energy CT imaging data

System of acquiring multi-energy CT imaging data

A CT system (10) includes a rotatable gantry (12) having an opening (48) for receiving an object (22) to be scanned, and a controller (28) configured to apply a first kVp (452) for a first time period (454), apply a second kVp (456) for a second time period (458), wherein the second time period (458...

Zusammenfassung:A CT system (10) includes a rotatable gantry (12) having an opening (48) for receiving an object (22) to be scanned, and a controller (28) configured to apply a first kVp (452) for a first time period (454), apply a second kVp (456) for a second time period (458), wherein the second time period (458) is different from the first time period (454), acquire a first asymmetric view dataset (550) during at least a portion of the first time period (454), acquire a second asymmetric view dataset (554) during at least a portion of the second time period (458), and generate an image using the acquired first and second asymmetric view datasets (550, 554).
