•The mask is pin-less and generally well tolerated. It feels like a warm washcloth on the head but tightens as time passes.

•Refixation can be done for repeated procedures within a week or so. Beyond that time further contraction of the mask makes it intolerably tight for patients (remaking the mask is an available option).

•High-definition faster imaging using multichannel head coils is possible. These images can be used for pre-planning and eventually co-registered with the CBCT images.

•Especially valuable in patients with bifrontal craniotomies where no suitable pin location (other than maxillary) is feasible.

•Pre-planning in advance can reduce overall treatment time on the day of treatment and enhance planning quality.
