Computed Tomography01:10

Computed Tomography

9.7K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Summary

Different commercial software packages show comparable accuracy for linear bone measurements from cone beam computed tomography (CBCT) images. The choice of software did not significantly impact results, ensuring reliable data for dental applications.

Area of Science:

  • Dentistry
  • Radiology
  • Medical Imaging

Background:

  • Accurate linear bone measurements are crucial in dentistry, particularly for implant planning.
  • Cone beam computed tomography (CBCT) is a widely used imaging modality.
  • Software used to analyze CBCT data may influence measurement accuracy.

Purpose of the Study:

  • To compare the accuracy of linear bone measurements using three different commercial software packages.
  • To evaluate the influence of software on the precision of measurements derived from CBCT data.

Main Methods:

  • Eight dry human mandibles were imaged using CBCT.
  • Linear measurements were taken in specific tooth regions using XoranCat®, OnDemand3D®, and KDIS3D® software.
  • A gold standard was established by physically sectioning the mandibles for comparison.

Main Results:

  • All software packages demonstrated excellent reproducibility (high Intraclass Coefficients).
  • OnDemand3D® and KDIS3D® showed minimal differences from the gold standard (-0.11 and -0.14 mm).
  • XoranCat® showed a slightly larger difference (+0.25 mm), but no statistically significant differences were found between any software and the gold standard (p > 0.05).

Conclusions:

  • The software package used for reconstructing images from CBCT DICOM data does not significantly influence linear bone measurements.
  • Clinicians can be confident in using various commercial software packages for accurate linear bone analysis in dentistry.
