Magnetic Resonance Guided Radiation Therapy (MRgRT) Prostate Motion and Margins

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study evaluated intra‐fractional prostate motion during MR‐guided radiotherapy to determine appropriate PTV margins for prostate cancer. Analysis of 18 patients resulted in calculated margins of 3.2 mm (AP), 1.7 mm (LR), and 3.2 mm (SI), supporting the potential for margin reduction with MRgRT. ABSTRACT Introduction Systematic and random errors in

A service for monitoring the quality of intraoperative cone beam CT images

open access: yesCurrent Directions in Biomedical Engineering, 2016
In recent years, operating rooms (ORs) have transformed into integrated operating rooms, where devices are able to communicate, exchange data, or even steer and control each other. However, image data processing is commonly done by dedicated workstations

Comparative Evaluation Accuracy Test Of CBCT (Ceat Of CBCT)

open access: yesJournal of Clinical Prosthodontics and Implantology.
This study aimed to analyze the accuracy of linear and angular measurements in different CBCT machines in comparison with the measurements obtained with a stereomicroscope in a dry human mandible. Eight landmarks on a dry human mandible were marked with 1mm gutta-percha round markers.

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

open access: yesJournal 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 ...

Effect of smoking over one pack daily on implant healing and health: A cohort study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This prospective cohort trial examines the effects of heavy smoking on peri‐implant marginal bone loss (MBL) and implant survival rates over 15 months. Methods Thirty subjects, categorized as either smokers (more than 20 cigarettes daily for over 5 years) or non‐smokers, were initially recruited with pocket depths ≤ 5 mm and at ...

Healing following ridge preservation using demineralized allograft particles or fibers alone, and combined with xenograft

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Allografts and xenografts are viable options for alveolar ridge preservation. This study evaluated histologic wound healing when using demineralized freeze‐dried bone allograft (DFDBA) alone, in fiber or particulate form, and in combination with xenograft. Alveolar dimensional changes were also evaluated.
