CT (Computed Tomography) and CBCT (Cone Beam Computed Tomography) are both imaging techniques used in medical diagnosis and treatment planning, but there are some differences between the two:
- Imaging Technology: CT uses a fan-shaped x-ray beam that rotates around the patient, while CBCT uses a cone-shaped x-ray beam that rotates around the patient. CBCT can sometimes provide 3D images with higher resolution, however, CT usually provides better contrast resolution.
- Radiation Exposure: CBCT typically involves a lower radiation dose than CT.
- Clinical Applications: CT is commonly used for diagnosis and treatment planning of a wide range of conditions, including cancer, trauma, and neurological disorders. CBCT is commonly used for dental and maxillofacial imaging, including orthodontics, oral and maxillofacial surgery, and implant placement.
While CT and CBCT are both forms of tomography, they differ in their imaging technology, radiation exposure, and clinical applications. The choice between CT and CBCT will depend on the specific clinical situation and the needs of the patient.
