Fast 4D cone-beam CT from 60 s acquisitions

open access: yesPhysics and Imaging in Radiation Oncology, 2018
Background & purpose: Four dimensional Cone beam CT (CBCT) has many potential benefits for radiotherapy but suffers from poor image quality, long acquisition times, and/or long reconstruction times. In this work we present a fast iterative reconstruction

Investigation of the radiation dose from cone‐beam CT for image‐guided radiotherapy: A comparison of methodologies

open access: yesJournal of Applied Clinical Medical Physics, 2017
Four methodologies were evaluated for quantifying kilovoltage cone‐beam computed tomography (CBCT) dose: the Cone‐Beam Dose Index (CBDI), IAEA Report 5 recommended methodology (IAEA), the AAPM Task Group 111 methodology (TG111), and the current dose ...

Bony Union in Maxilla and Mandible Free Flap Reconstruction: A Systematic Review and Meta‐Analysis

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Bony nonunion is an important complication in head and neck reconstruction, but its definition, incidence, and treatment are not well‐reported. Methods MEDLINE, Embase, CENTRAL, and Web of Science were searched from October 1st, 1990 to January 6th, 2025 for studies reporting bony union for maxilla or mandible reconstruction with ...

FDK Half-Scan with a Heuristic Weighting Scheme on a Flat Panel Detector-Based Cone Beam CT (FDKHSCW)

open access: yesInternational Journal of Biomedical Imaging, 2006
A cone beam circular half-scan scheme is becoming an attractive imaging method in cone beam CT since it improves the temporal resolution. Traditionally, the redundant data in the circular half-scan range is weighted by a central scanning plane-dependent ...

Cone beam CT for QA of synthetic CT in MRI only for prostate patients

open access: yesJournal of Applied Clinical Medical Physics, 2018
Purpose Magnetic resonance imaging (MRI)‐only radiotherapy is performed without computed tomography (CT). A synthetic CT (sCT) is used for treatment planning. The aim of this study was to develop a clinically feasible quality assurance (QA) procedure for

Hypervision Proton Surgery: The Future Direction of Proton Therapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

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
