Clinical commissioning of an adaptive radiotherapy platform: Results and recommendations

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Online adaptive radiotherapy platforms present a unique challenge for commissioning as guidance is lacking and specialized adaptive equipment, such as deformable phantoms, are rare. We designed a novel adaptive commissioning process consisting of end‐to‐end tests using standard clinical resources.

Volume staging for arteriovenous malformation SRS treatment using VMAT

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Volume staging involves dividing the target volume into smaller parts and treating each part separately. In this study, the feasibility of volume‐staged stereotactic radiosurgery (VS‐SRS) on a linear accelerator using volumetric modulated arc therapy (VMAT) and a frameless patient positioning system is investigated.

Accuracy of patient dose estimation in cone beam computed tomography in breast irradiation by size‐specific dose estimates with position correction

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract This study aims to investigate the effects of the position correction of size‐specific dose estimates (SSDE) on patient dose estimation in cone beam computed tomography (CBCT). The relationship between the phantom position and absorbed dose in the right breast was studied using optically stimulated luminescence dosimeters and a simulated human

Cone beam computed tomography in endodontics [PDF]

open access: yesBrazilian Dental Journal, 2012
Cone beam computed tomography (CBCT) is a contemporary, radiological imaging system designed specifically for use on the maxillo-facial skeleton. The system overcomes many of the limitations of conventional radiography by producing undistorted, three-dimensional images of the area under examination.

Learned Cone-Beam CT Reconstruction Using Neural Ordinary Differential Equations [PDF]

open access: yes7th International Conference on Image Formation in X-Ray Computed Tomography, Proc. Vol. 12304 (2022), 2022
Learned iterative reconstruction algorithms for inverse problems offer the flexibility to combine analytical knowledge about the problem with modules learned from data. This way, they achieve high reconstruction performance while ensuring consistency with the measured data.

Automatic and Computationally Efficient Alignment in Fan- and Cone-beam Tomography [PDF]

open access: yes, 2023
This work is concerned with fan- and cone-beam computed tomography with circular source trajectory, where the reconstruction inverse problem requires an accurate knowledge of source, detector and rotational axis relative positions and orientations. We address this additional inverse problem as a preceding step of the reconstruction process directly ...

The diagnostic potential of cone beam computed tomography for cervical spine injuries in children: a review of two reports

open access: yesAlʹmanah Kliničeskoj Mediciny, 2023
Compared to multiaxial computed tomography, the cone beam computed tomography has its benefits in terms of higher resolution imaging, including the construction of a 3D image, and in terms of several fold lower radiation exposure.
