Surgiscope System manufactured by Elekta AB (Stockholm, Sweden) which can be used for
the tracking of instruments and cortical surface movement in the OR.
FIGURE 15.16
Using high-resolution digital photographs captured in the OR (left two images), cortical
surface patterns can be manipulated with image morphing techniques (right image) to
generate a spatial distribution of cortical surface movement that can subsequently be used
as input for model updates.
tumor) segmented (Figure 15.17b) and overlayed (Figure 15.17d) with the pre-
operative MR (Figure 15.17c), and also registered in OR coordinates in order to
define baseline conditions and estimate registration errors. From this estab-
lished state, subsequent movements in these boundaries can be followed with
the ultrasound and supplied to the model as known data. The model is
