Figure 5. Computed Tomography (CT) Scanner attachments. The left image is a head-ring fixture which holds the head-ring of a patient during a CT scan acquisition. The right image shows the Brown-Roberts-Wells (BRW) Localizer Frame (LF) with the Cosman-Roberts-Wells (CRW) system being supported by the headring fixture and restrained with brackets. This type of arrangement reduces noise during image acquisition and allows the posterior N-Localizer to be imaged well.
