Assessment of Accuracy and Reliability of Linear Measurements of CBCT- An in vitro study
Journal Title: Indian Journal of Applied Radiology - Year 2017, Vol 3, Issue 1
Abstract
Objectives: Cone Beam Computed Tomography (CBCT) is an innovative dental imaging system characterized by rapid volumetric imaging and allows us to obtain linear measurements in three dimensions using computer software. In order to optimize application of the technique in various fields it is necessary to analyse the accuracy of the data obtained on performing linear measurements. The present study intends to compare the linear measurements made on dry mandible with those made on CBCT images. Method: The study consisted of 15 human dry mandibles. Sixteen linear measurements including 8 horizontal and 8 vertical, were made at different anatomical points of the dry mandible using Digital Vernier calliper. CBCT images were then obtained for the mandibles. The same linear measurements were done on the CBCT image using ONDEMAND 3D and Scanora softwares. Results and Conclusion: Both the CBCT and the caliper measurements were highly reliable. The CBCT measurements tended to slightly underestimate the anatomic truth.
