Cone Beam CT
Low-dose 3D dental/ENT imaging with cone-beam geometry.
What is Cone?
Low-dose 3D dental/ENT imaging with cone-beam geometry.
How it works: A cone-shaped X-ray beam rotates around the patient's head, capturing data from multiple angles. This data is reconstructed into detailed 3D images of the bones, teeth, and surrounding structures.
Common Uses of Cone
Dental implant planning
Evaluates bone volume and density for optimal implant placement
Orthodontic assessment
Visualizes impacted teeth and dental anomalies for treatment planning
TMJ evaluation
Assesses joint morphology and disc position for TMJ disorders
Advantages
- ✓Noninvasive or minimally invasive
- ✓Widely available in centers
- ✓Guides management
- ✓Low radiation exposure
- ✓High 3D resolution
- ✓Fast acquisition time
Limitations
- ⚠Limited by operator or motion
- ⚠May need contrast or prep
- ⚠Not perfect specificity
- ⚠Limited soft tissue contrast
- ⚠Metallic artifacts
- ⚠Larger FOV reduces resolution

⚖️Cone vs CT
Related Imaging Modalities
Complements conventional CT for specific dental and maxillofacial applications. Superior to 2D dental radiographs for complex cases but less comprehensive than full-body CT for systemic evaluation. MRI provides better soft tissue detail for ENT pathology.
CT
CT scans use X-rays to create detailed cross-sectional images of the body. They are particularly useful for detecting bone fractures, tumors, and internal bleeding.
MRI
MRI uses powerful magnets and radio waves to produce detailed images of organs and soft tissues. Excellent for brain, spine, and joint imaging.
Ultrasound
Ultrasound uses sound waves to create real-time images. Commonly used for pregnancy monitoring and examining organs like the heart, liver, and kidneys.
