NEW HEAD-POSITIONING SYSTEM FOR USE WITH COMPUTED TOMOGRAPHIC SCANNING

A new head-positioning system has been developed to hold the head firmly during the performance of a computed tomograhic scan and to position the head reproducibly during repeat scans. This can be used to maintain the head in position during long scanning sessions, to relate a lesion to landmarks on scout views, to follow lesions in repeated scans over time, and to perform a variety of invasive procedures.
