Simulated reconstruction of Young's Modulus in a coronal brain cross section where (a) is the
original Young's Modulus distribution provided by image-to-grid segmentation as described
in Figure 15.13 and (b) is the reconstructed modulus distribution from synthetic displacement
measurements having 10% noise.

ment within the image pair.
Intraoperative ultrasound is a low-cost imaging technology which can also be
registered in the OR coordinate system and potentially provide control points
as model constraints during intraoperative image updating.

Figure 15.17
illustrates how this might function. At the start of a case, ultrasound image
sweeps can be recorded (Figure 15.7a), echogenic structures (e.g., ventricles,
