A Metric for Testing the Accuracy of Cross-Modality Image Registration: Validation and Application

Abstract: (a) We have defined a reliable, sensitive metric that can stringently test the accuracy of various image registration techniques. (b) The AIR algorithm leaves modest error after aligning PET blood flow and anatomic MR images of baboon brain.

“…Fiducial markers have largely been used to provide a method for “perfect registration” to assess the accuracy of other automated registration algorithms. These studies have incorporated fiducial markers into stereotactic frames rather than directly attaching them or implanting them into the animal (Black et al, 1996; Humm et al, 2003; Rowland et al, 2005). As mentioned previously, a major limitation of this method is the inability to apply such an approach retrospectively.…”

“…The head of the sedated animal was fixed in position with a headholder system that bolted to a acrylic "cap" surgically implanted in the skull and also to the PET scanning table (Perlmutter et al, 1991a). This ensured no movement of the head throughout the scan (Black et al, 1996a).…”

“…1). We have previously validated this method in baboons by reference to external fiducials attached to the headholder system and visible in both modalities; the maximum residual error at the GP after AIR alignment was 2.4 mm (mean error, 2.0 mm) (Black et al, 1996a).…”

“…Alternative approach is automatic image registration (AIR) which iteratively adjusts spatial transformation parameters (rotation and translation) so as to maximize some similarity measure computed between the transformed target image and the corresponding reference image. (Black et al, 1996;Viergever et al, 2001;Zitova & Flusser, 2003;Bentoutou et al, 2005;DelMarco et al, 2007;Liu et al, 2008) There is a variety of automatic intensity based measures, which do not require the definition of GCPs or features. The criterion of maximization of mutual information (MI) has proven to be a breakthrough in the field of image registration.…”
