CBCT correction using a cycle-consistent generative adversarial network and unpaired training to enable photon and proton dose calculation

Physics in Medicine and Biology, 2019
In presence of inter-fractional anatomical changes, clinical benefits are anticipated from image-guided adaptive radiotherapy. Nowadays, cone-beam CT (CBCT) imaging is mostly utilized during pre-treatment imaging for position verification. Due to various

Clinical decision making and importance of the AAOMR/AAE position statement for CBCT examination in endodontic cases.

International Endodontic Journal, 2020
AIM To compare conventional radiographic and cone beam computed tomography (CBCT) findings with reference to the American-Association-of-Endodontics and American-Academy-of-Oral-and-Maxillofacial-Radiology (AAE/AAOMR) joint position statement and to ...

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 ...

Historical Perspectives on CBCT

2018
There can be no denying that Cone Beam Computerized Tomography (CBCT) is an in-office diagnostic imaging technology that has taken maxillofacial imaging by storm (Farman 2006; Farman and Scarfe 2006; Farman et al. 2005, 2007a, b; Hayakawa et al. 2005; Kursaglu et al. 2005; Scarfe et al.

High-quality Initial Image-guided 4D CBCT Reconstruction.

Medical Physics (Lancaster), 2020
PURPOSE Four-dimensional cone-beam computed tomography (4D CBCT) has been developed to provide a sequence of phase-resolved reconstructions in image-guided radi-ation therapy. However, 4D CBCT images are degraded by severe streaking artifacts because the

Incidental Findings on CBCT

2017
An incidental finding is a generic term applied in radiology to describe an occult entity discovered unexpectedly on an imaging examination performed for an unrelated reason. Some incidental findings on cone beam computed tomography (CBCT) images are readily identifiable based on radiologic presentation and location (e.g., tonsilloliths) whereas others

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.

Endodontic Applications of CBCT

2017
Endodontics is the specialty of dentistry concerned with the morphology, physiology, and pathology of the human dental pulp and periradicular tissues. Its study and practice encompasses the basic and clinical sciences including the biology of the normal pulp and the etiology, diagnosis, prevention, and treatment of diseases and injuries of the pulp and

A preliminary study of using a deep convolution neural network to generate synthesized CT images based on CBCT for adaptive radiotherapy of nasopharyngeal carcinoma

Physics in Medicine and Biology, 2019
This study aims to utilize a deep convolutional neural network (DCNN) for synthesized CT image generation based on cone-beam CT (CBCT) and to apply the images to dose calculations for nasopharyngeal carcinoma (NPC).

Absorbed dose and image quality of Varian TrueBeam CBCT compared with OBI CBCT

Physica Medica, 2016
Nowadays, patient positioning and target localization can be verified by using kilovolt cone beam computed tomography (kV-CBCT). There have been various studies on the absorbed doses and image qualities of different kV-CBCT systems. However, the Varian TrueBeam CBCT (TB CBCT) system has not been investigated so far.
