Effect of Different Voxel Sizes on Accuracy of CBCT Linear Measurements: Preclinical Study

January 23, 2018 updated by: Mohamed Ahmed Mohamed Selim, Cairo University

Effect of Different Voxel Sizes on Accuracy of 2D and 3D Mandibular Linear Measurements Using CRANEX® 3D Cone Beam Computed Tomography Machine: Preclinical Study

study target is assessment of the accuracy of linear measurement obtained from CBCT images on 3D volumetric rendering and multiplanar slices with different voxel sizes

Study Overview

Status

Unknown

Conditions

Intervention / Treatment

Detailed Description

The real linear measurement will be measured in millimeter (mm) on the mandibles using digital caliper in the chosen areas.

CBCT images will be viewed by OnDemand3D™ viewer software and linear measurements using 2D ruler on multiplanar slices and 3D ruler on 3D volumetric rendering to assess for the dimension in the chosen areas.
