Abstract:
1. A method of image registration, comprising: setting a predetermined pixel intensity threshold; generating a first volumetric image scan from a first imaging modality, the first volumetric image scan comprising at least one first slice of an object, in turn, comprising a first plurality of pixels; identifying first target pixels from the first plurality of pixels, wherein the first target pixels exceed the predetermined pixel intensity threshold; creating a first energy profile from the first target pixels; generating a second image scan from a second imaging modality, the second image scan comprising at least one second slice of the object, in turn, comprising a second plurality of pixels; identifying second target pixels from the second plurality of pixels, wherein the second target pixels exceed the predetermined pixel intensity threshold; creating a second energy profile from the second target pixels; comparing the first energy profile to the second energy profile to match the region of interest in the first volumetric image scan and the second volumetric image scan, wherein the first imaging modality is different from the second imaging modality.
