[PDF][PDF] A Posterization Strategy for the Registration of [123I] FP-CIT SPECT Brain Images.
VISAPP (3), 2015•scitepress.org
A fully automatic procedure to build a [123I] FP-CIT SPECT template in the MNI-space using
only information from the source images is presented. This approach does not require the
acquisition of patient-specific brain magnetic resonance image. This fully automatic
procedure uses, firstly, the Otsu's method to outline the source images; secondly, a threshold
strategy to posterize the source images and the template and, lastly, an affine registration
algorithm by the optimization of a square root of sum of squares cost function.

Abstract
A fully automatic procedure to build a [123I] FP-CIT SPECT template in the MNI-space using only information from the source images is presented. This approach does not require the acquisition of patient-specific brain magnetic resonance image. This fully automatic procedure uses, firstly, the Otsu’s method to outline the source images; secondly, a threshold strategy to posterize the source images and the template and, lastly, an affine registration algorithm by the optimization of a square root of sum of squares cost function.
