Trans${^2}$-CBCT: A Dual-Transformer Framework for Sparse-View CBCT Reconstruction

CoRR
Cone-beam computed tomography (CBCT) using only a few X-ray projection views enables faster scans with lower radiation dose, but the resulting severe under-sampling causes strong artifacts and poor spatial coverage. We address these challenges in a unified framework.

A novel AI model for detecting periapical lesion on CBCT: CBCT-SAM

Journal of Dentistry
Periapical lesions are not always evident on radiographic scans. Sometimes, asymptomatic or initial periapical lesions on cone-beam computed tomography (CBCT) could be missed by inexperienced dentists, especially when the scan has a large field of view and is not for endodontic treatment purposes. Previously, numerous algorithms have been introduced to

CBCT IN ORTHODONTICS

Cone Beam Computed Tomography (CBCT) has significantly transformed orthodontic diagnosis and treatment planning by providing three-dimensional visualization of craniofacial structures with high accuracy and detail. Unlike conventional two-dimensional radiographic techniques, CBCT offers comprehensive assessment of dental, skeletal, and soft tissue ...

CBCT in Endodontics

Dental Poster Journal, 2020
Cone beam computed tomography (CBCT) has become indispensable radiographic modality for dentists as it provides high-quality, accurate three-dimensional (3D) representations of maxillofacial structures. CBCT is integral part of guided endodontics. Understanding of field of view, CBCT image acquisition and reconstruction, and artifact reduction are ...

Artefacts in CBCT: a review [PDF]

Dentomaxillofacial Radiology, 2011
Artefacts are common in today's cone beam CT (CBCT). They are induced by discrepancies between the mathematical modelling and the actual physical imaging process. Since artefacts may interfere with the diagnostic process performed on CBCT data sets, every user should be aware of their presence.

CBCT in orthodontics

International journal of health sciences, 2022
Most orthodontic patients, unlike those having implants or endodontic treatment, are children who are particularly vulnerable to ionising radiation. In orthodontics, cone-beam computed tomography (CBCT) has both hazards and benefits. Ionizing radiation, the existence of artefacts, higher costs, limited accessibility, and the need for additional ...

Comparison of the CBCT, CT, 3D printing, and CAD-CAM Milling options for the most accurate root form duplication required for the root analogue implant (RAI) protocol

Journal of Indian Academy of Oral Medicine and Radiology, 2021
Background: A computerized tomography (CT) scan or a cone beam computerized tomography (CBCT) imaging techniques can be used for tooth segmentation and acquisition of a three-dimensional (3D) reconstruction using CADCAM milling and 3D printing methods ...

Detection of mandibular canal in human dry mandibles with cone beam computed tomography using 270° and 360° protocols under continuous and pulse modes – A comparative study

Journal of Indian Academy of Oral Medicine and Radiology, 2021
Background: Cone beam computed tomography (CBCT) enables practitioner to accurately localize and mark the nerve canal. The rotation of the X-ray tube and the detector around the patient's head produces multiple projection images.
