Comparison Between CBCT and Fusion PET/CT-CBCT Guidance for Lung Biopsies

CardioVascular and Interventional Radiology, 2020
To establish the feasibility of performing percutaneous biopsy of lung lesions guided by fusion PET/CT-CBCT and to evaluate whether the metabolic information provided by a prior PET/CT scan add incremental benefits for diagnosis.We retrospectively reviewed data from 180 patients who underwent CBCT-guided lung biopsy (group 1-90 cases) or PET/CT-CBCT ...

Evaluating airway volume with CBCT

American Journal of Orthodontics and Dentofacial Orthopedics, 2012
With interest, we read the Techno Bytes article on analyzing airway volume by using cone-beam computed tomography (CBCT) in the May 2012 issue of the AJO-DO. The authors used the data from CBCT scans to obtain resin-negative prototypes of the airway. The resin prototypes were scanned again in CBCT, and the airway volumes of the prototypes were measured

Dental CBCT equipment and performance issues

Radiation Protection Dosimetry, 2012
Dental cone beam computed tomography (CBCT), also known as digital volumetric tomography was developed in the late 1990s and is now increasingly available in clinical practice. It can provide high resolution cross-sectional images of teeth and the maxillofacial region with applications in all branches of dentistry. As a new imaging modality, there were

Basic CBCT Anatomy

2013
Cone-beam computed tomography (CBCT) has been demonstrated to be an advance in dental and maxillofacial imaging. It has become increasingly important in implant dentistry and in the fields of endodontics and orthodontics. Also, radiation dose can be kept as low as reasonably achievable.

Pijn en CBCT

Tandartspraktijk, 2011
Van 14 tot 17 september dit jaar werd in Rome het ‘15th Biennial Congress of the European Society of Endodontics’ gehouden,met als thema ‘Not only roots’. Over het feit dat Rome natuurlijk een verrukkelijke stad is voor een congres hoef ik denk ik niet verder uit te wijden.

CBCT-Based Synthetic MRI Generation for CBCT-Guided Adaptive Radiotherapy

2019
Cone-beam computed tomography (CBCT) has been widely used in image-guided radiation therapy for patient setup to improve treatment performance. However, the low soft tissue contrast on CBCT may limit its utility when soft tissue alignment is of interest.

CBCT Quality Assurance

2017
Quality Assurance (QA) is an essential aspect of medical imaging, ensuring that X-ray imaging modalities provide adequate diagnostic information at exposures that are as low as reasonably/diagnostically acceptable (ALARA/ALADA), minimizing the potential radiation risk to the patient.
