Par0044 - elastix

Registration Description

intra-subject; multi-image; affine (Mutual Information) + multi-image B-spline transformation (Mutual Information and mean square difference);

Image data

Single phase cardiac CTA acquired in diastole, slice thickness 0.4 mm, in plane resolution 0.35 mm.

CT perfusion (reference frame from dynamic CTP sequence)

Dynamic stress CTP after adenosine acquired in end diastole. Reconstructed with a 2 mm thickness and in plane resolution of 0.35 mm using a medium-smooth B23f kernel. From the reconstructed sequence a single frame is selected based on maximum contrast and best alignment with perfusion map.

Application

Registration of myocardium from CTA to CT perfusion using myocardial territory labels for regularization
