The prompt use of computerized tomography has significantly enhanced the early localization of traumatic posterior fossa hematoma of the brain. Consequently, timely surgical intervention has been possible before irreversible damage has set in. The result is an overall improvement in the survival of patients with this condition.

This paper presents a method for volumetric reconstruction from Helical Computerized Tomography (H-CT) data which are collected with a fan beam source. An interpretation of the HCT data in terms of the Axial Computerized Tomography (ACT) data is provided. This analysis indicates that the H-CT data for positive and negative detector angles can be combined to form periodically nonuniform hexagona...
