Author(s): Akshayaa L and Jayanth Kumar Vadivel*
Background
Cone-beam computerized tomography (CBCT) is a medical imaging
acquisition system with a cone shaped X ray beam centered in a two
dimensional detector. It allows the clinicians to analyse the craniofacial
structures of jaw, bone and teeth in three dimensional resolution. It
provides many advantages in dental treatments, planning with a lower
radiation exposure.
Aim
The primary objective of our present study was to analyse and compare
the hounsfield units between the two CBCT machines.
Materials And Methods
A 3 dimensional radiographic phantom made up of poly methyl
methacrylate (PMMA); clear acrylic. The length of the phantom measures
about 4cm and width of 2.5 cm. This radiographic phantom contains four
different materials : a lead foil, GP sticks, metal bal.. View More»
