Cone Beam CT Study of Temporal Crest Canal

Journal of Dentistry, 2018
Statement of the Problem: It is crucial for clinicians to be certain about the location of mandibular canal and determine any anatomical variants relevant to it. The temporal crest canal (TCC) is a rare anatomical variant of mandibular canal that lack of

GPU-Based 3D Cone-Beam CT Image Reconstruction for Large Data Volume

International Journal of Biomedical Imaging, 2009
Currently, 3D cone-beam CT image reconstruction speed is still a severe limitation for clinical application. The computational power of modern graphics processing units (GPUs) has been harnessed to provide impressive acceleration of 3D volume image ...

Radiation Dose and Risk in the Radiological Investigation of Suspected Non‐Accidental Injury (NAI)

Journal of Medical Radiation Sciences, EarlyView.
This study is a retrospective analysis of 362 skeletal surveys performed over a 5‐year period for children under 5 years of age for suspected non‐accidental injury. We present effective dose data and the associated risks of radiation exposure for initial and follow‐up examinations.

Intrafraction motion and impact of margin reduction for MR‐Linac online adaptive radiotherapy for pancreatic cancer treatments

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 17-24, March 2025.
This analysis included quantification of intrafraction motion in pancreas stereotactic ablative radiotherapy treated on the MR‐Linac, leading to the development of adjusted (PTV) margins. Intrafraction motion indicated an average target displacement of 1–3 mm, resulting in an adjusted PTV margin of 2 mm in the right–left and superior–inferior ...

Volumetric buccal bone alterations at immediate implant sites with or without soft tissue augmentation: A 6‐month assessment

Journal of Periodontology, EarlyView.
Abstract Background This study is part of a randomized controlled trial investigating the impact of soft tissue augmentation (STA) using subepithelial connective tissue graft (SCTG) (immediate implant with subepithelial connective tissue graft [ICT] group) or acellular dermal matrix (ADM) (immediate implant with acellular dermal matrix [IAD] group ...

Hybrid operating room with ceiling mounted imaging system assisted pre-operative and intra-operative lung nodule localization for thoracoscopic resections: a 5-year case series

Journal of Cardiothoracic Surgery
Background Video-assisted thoracoscopic (VATS) lung resections are increasingly popular and localization techniques are necessary to aid resection. We describe our experience with hybrid operating room (OR) cone-beam computed tomography (CT) assisted pre-

Probiotic consumption reduces alveolar bone loss and kidney damage in pregnant rats with experimental periodontitis

Journal of Periodontology, EarlyView.
Abstract Background Bifidobacterium animalis subsp. lactis HN019 (B. lactis HN019) is a probiotic bacterial strain with immunomodulatory properties. Its benefits have been observed in healthy and systemically compromised animals with periodontitis (PD). Our objective was to investigate the local and systemic effects of the systemic administration of B.
