Current Approaches for Image Fusion of Histological Data with Computed Tomography and Magnetic Resonance Imaging

Table 3

List of volume-to-volume registration strategies discussed in this review. Due to a lack of information, a direct comparison according to the relative accuracy was not possible since only Rusu et al. [80] and Lee et al. [81] provided sufficient data. Therefore, there can be no quantitative evaluation.
