Computed Tomography

Computed Tomography

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...

Background:

Maxillofacial cone beam computed tomography (CBCT) represents a significant advancement in dental imaging.
CBCT offers more detailed 3D information compared to traditional 2D radiography.

Purpose of the Study:

To provide an overview of maxillofacial CBCT principles.
To explain task-specific equipment, image selection, and display modes.
To outline a systematic methodology for CBCT image interpretation.

Main Methods:

Discusses fundamental principles of CBCT operation.
Highlights the importance of 'task specific' parameter selection for dose reduction and image quality.
Emphasizes the need for understanding 3D maxillofacial anatomy and normal variations.

Main Results:

CBCT acquisition requires careful consideration of numerous parameters for appropriate and task-specific use.
Effective use necessitates knowledge of exposure settings, geometric and software parameters, and image formatting.
Interpretation requires thorough understanding of 3D anatomy and its variations.

Conclusions:

Best practices in maxillofacial CBCT involve understanding principles, task-specific protocols, and systematic interpretation.
Appropriate use of CBCT parameters ensures diagnostic image quality while minimizing patient dose.
A systematic approach to interpretation is essential for accurate diagnosis using detailed CBCT data.
