WebThis arrangement (single detector and single narrow beam with translate–rotate motion) is referred to as first-generation CT geometry and required 5–6 min to complete a scan. To minimize examination time, the Mark I scanner actually used 2 adjacent detectors and a 26-mm-wide x-ray beam (in the slice thickness direction) to simultaneously collect data for 2 … WebBackground . Understanding the anatomy and morphological variability of the orbital region is of great importance in clinical practice, forensic medicine, and biological anthropology. Several methods are used to estimate sex based on the skeleton or parts of the skeleton: classic methods and the geometric morphometric method. The objective of this research …
