Patent ID: 8031828

Claim:
A method, comprising: acquiring a first set of projection data using a first portion of a detector and a helical scan protocol, wherein an X-ray beam is collimated to a fan shape for the helical scan protocol; generating a first volumetric representation using the first set of projection data; using the first volumetric representation to configure one or more imaging parameters before acquiring a second set of projection data; acquiring the second set of projection data using a second portion of the detector and an axial scan protocol, wherein the first portion is shaped differently than the second portion and the X-ray beam is collimated to a cone shape for the axial scan protocol; supplementing the second set of projection data based upon the first set of projection data or data derived using the first set of projection data to generate a supplemented set of projection data; and generating a second volumetric representation using the supplemented set of projection data.
