Figure 2.

Checkerboard overlays showing volumetric affine registration results (each row corresponds to a different patient study), (a),(c) ${𝒞}_{t2}^{\mathit{\text{post}}}/{𝒞}_{t2}^{\mathit{\text{pre}}}$ and (b),(d) ${𝒞}_{adc}^{\mathit{\text{pre}}}/{𝒞}_{t2}^{\mathit{\text{pre}}}$. Green outlines correspond to the prostate capsule segmentation (obtained via expert annotation of the T2w MRI). Note contiguous structures in each of these checkerboards denoting successful co-registration using affine registration, implying that more complex deformable registration procedure was not necessary in these cases.
