Quantitative quality control of 3D water tank using image analysis

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background and objective Accurate beam data acquisition using three‐dimensional (3D) water tanks is essential for beam commissioning and quality control (QC) in clinical radiation therapy. This study introduces a novel method for quantitative QC of the system, utilizing MV images and webcam videos.

Structure of singularities in the nonlinear nerve conduction problem [PDF]

arXiv, 2019
We give a characterisation of the singular points of the free boundary $\partial \{u>0\}$ for viscosity solutions of the nonlinear equation \begin{equation}F(D^2 u)=-\chi_{\{u>0\}},\tag{0.1} \end{equation} where $F$ is a fully nonlinear elliptic operator and $\chi$ the characteristic function.

Dosimetric evaluation and clinical application of collimated apertures with proton beam line scanning in stereotactic radiotherapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Stereotactic radiotherapy (SRT) is a highly effective treatment with precision for small, localized lesions. Proton therapy, characterized by the Bragg peak, offers superior dose conformity compared to photon‐based approaches. However, challenges remain in minimizing lateral penumbra and optimizing dose delivery, particularly for small

Normative values and factors affecting saphenous nerve responses in a south Asian population: a cross-sectional neurophysiological study at a tertiary care hospital in Pakistan

BMC Neurology
Background The saphenous nerve, a sensory branch of the femoral nerve, is not commonly included in routine lower extremity nerve conduction studies due to a high frequency of non-recordable responses in healthy subjects.

Claustrum Volume Is Reduced in Multiple Sclerosis and Predicts Disability

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The claustrum is a small, thin structure of predominantly gray matter with broad connectivity and enigmatic function. Little is known regarding the impact of claustrum pathology in multiple sclerosis (MS). Methods This study assessed whether claustrum volume was reduced in MS and whether reductions were associated with specific ...

Ghrist Barcoded Video Frames. Application in Detecting Persistent Visual Scene Surface Shapes captured in Videos [PDF]

arXiv, 2019
This article introduces an application of Ghrist barcodes in the study of persistent Betti numbers derived from vortex nerve complexes found in triangulations of video frames. A Ghrist barcode is a topology of data pictograph useful in representing the persistence of the features of changing shapes.
