Volume staging for arteriovenous malformation SRS treatment using VMAT
Journal 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.

White-headed Vultures Trigonoceps occipitalis show visual field characteristics of hunting raptors [PDF]
, 2017 The visual fields of Aegypiinae vultures have been shown to be adapted primarily to meet two key perceptual challenges of their obligate carrion-feeding behaviour: scanning the ground and preventing the sun’s image falling upon the retina.

Journal 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

Information Optimization in Coupled Audio-Visual Cortical Maps [PDF]
, 2002 Barn owls hunt in the dark by using cues from both sight and sound to locate their prey. This task is facilitated by topographic maps of the external space formed by neurons (e.g., in the optic tectum) that respond to visual or aural signals from a ...

Accuracy and feasibility of an android-based digital assessment tool for post stroke visual disorders - The StrokeVision App [PDF]
, 2018 Background: Visual impairment affects up to 70% of stroke survivors. We designed an app (StrokeVision) to facilitate screening for common post stroke visual issues (acuity, visual fields and visual inattention).

Cortical feedback signals generalise across different spatial frequencies of feedforward inputs [PDF]
, 2018 Visual processing in cortex relies on feedback projections contextualising feedforward information flow. Primary visual cortex (V1) has small receptive fields and processes feedforward information at a fine-grained spatial scale, whereas higher visual ...

Visualization Resources: A Starting Point [PDF]
, 2021 Visualization, as a vibrant field for researchers, practitioners, and higher educational institutions, is growing and evolving very rapidly. Tremendous progress has been made since 1987, the year often cited as the beginning of data visualization as a distinct field.

The cognitive neuroscience of visual working memory [PDF]
, 2017 Visual working memory allows us to temporarily maintain and manipulate visual information in order to solve a task. The study of the brain mechanisms underlying this function began more than half a century ago, with Scoville and Milner’s (1957) seminal ...
