in case of stereotactic and thermoplastic masks were
compared and analysed for both intracranial and neck regions.á Results in case of automatic bone matching, the mean
length of the displacement vector in stereotactic masks for intracranial regions
was 3.12▒1.52 mm, for the neck region 5.86▒2.94 mm. This vector in case of thermoplastic masks
for intracranial regions was 4.72▒1.74 mm, for the neck region 7.26▒4.45 mm. áResults with manual matching were similar.
