illumination was used to confirm if the NasoXplorer could capture images
where the points were if it had a camera inside.
Using this set-up, the NasoXplorer successfully pointed at all the points
inside the skull. Hence, it can capture all parts of the nasopharyngeal region.

4 Design review

We conducted a Design Review to study design results, serve as feedback
control, and assess the progress of the project. The NasoXplorer provides
