Applicant: GENERAL ELECTRIC COMPANY
Inventor： Debashish Pal , Jiang Hsieh , Paavana Sainath , Girijesh Yadava , Brian Edward Nett
IPC: G01N23/04
CPC classification number: G01N23/046 , A61B6/032 , A61B6/482 , A61B6/488 , A61B6/5258 , A61B6/545 , G01V5/005
Abstract: An imaging system includes a rotatable gantry for receiving an object to be scanned, a generator configured to energize an x-ray source to generate x-rays, a detector positioned to receive the x-rays that pass through the object, and a computer. The computer is programmed to obtain knowledge of a metal within the object, scan the object using system scanning parameters, reconstruct an image of the object using a reconstruction algorithm, and automatically select at least one of the system scanning parameters and the reconstruction algorithm based on the obtained knowledge.
