Three dimensional (3D) pre-scan based volumetric image data processing
First Claim
1. A method, comprising:
- determining a registration transform between first three dimensional pre-scan image data and second three dimensional pre-scan image data based on a predetermined registration algorithm; and
registering first volumetric scan image data and second volumetric scan image data based on the registration transform, generating registered image data,wherein a field of view of the first volumetric scan image data is less than a field of view of the first three dimensional pre-scan image data, and a field of view of the second volumetric scan image data is less than a field of view of the second three dimensional pre-scan image data.

Abstract
A method includes determining a registration transform between first three dimensional pre-scan image data and second three dimensional pre-scan image data based on a predetermined registration algorithm. The method further includes registering first volumetric scan image data and second volumetric scan image data based on the registration transform. The method further includes generating registered image data. A system (100) includes a pre-scan registerer (122) that determines a registration transform between first three dimensional pre-scan image data and second three dimensional pre-scan image data based on a predetermined registration algorithm. The system further includes a volume registerer (126) that registers first volumetric scan image data and second volumetric scan image data based on the registration transform, generating registered image data.
