Table 2 Likert score criteria for scoring landmark registration

From: Segmentation-guided multi-modal registration of liver images for dose estimation in SIRT

Score Criteria
1 Major misalignment exists for the registration. Major impact on dosimetry is expected. Dosimetry results are deemed unreliable
2 Pronounced misalignment exists for the registration. Substantial impact on dosimetry is expected
3 Moderate misalignment exits for the registration. Moderate impact on dosimetry is expected
4 Little misalignment exists for the registration. No significant impact on dosimetry is expected
5 Near perfect alignment for the registration. No intervention is warranted and dosimetry is deemed reliable
