Results

All six chosen individuals could successfully be matched and subsequently be evaluated. After implementing the workflow, the time needed to complete the registration steps was less than 5 minutes before routine insonation with matched imaging could be started (time for MRI data download not included). The accuracy of registration performance was tested ipsilateral to the US acquisition, which was obtained through the right temporal US window (Fig. 7).

 

In more than 70% of the cases the residual error in the points of reference was 0 mm, in one case it was 3 mm and in the remaining cases it was 1 mm. The error was not significantly different from 0 mm (p-value=0.8). In the following Table the detailed measurements for each subject are reported (in mm), the axial imaging plane is considered, with ipsilateral measurements.
