In vivo confocal microscopy of verticillata-like paraproteinemic keratopathy in a patient with monoclonal gammopathy of uncertain significance evolving into smoldering multiple myeloma

American Journal of Ophthalmology Case Reports, 2019
Purpose: To highlight the utility of in vivo confocal microscopy (IVCM) in the microstructural characterization of corneal deposits resembling vortex keratopathy in a case of secondary deposition keratopathy due to an evolving monoclonal gammopathy ...

Bayesian Dynamical Modeling of Fixational Eye Movements [PDF]

arXiv, 2023
Humans constantly move their eyes, even during visual fixations, where miniature (or fixational) eye movements are produced involuntarily. Fixational eye movements are composed of slow components (physiological drift and tremor) and fast microsaccades.

The coeruleus/subcoeruleus complex in idiopathic rapid eye movement sleep behaviour disorder.

Brain : a journal of neurology, 2016
Idiopathic rapid eye movement sleep behaviour disorder is characterized by nocturnal violence, increased muscle tone during rapid eye movement sleep and the lack of any other neurological disease.

Evaluation of the dose reduction effect of crystalline lens exposure in cone‐beam computed tomography with bismuth eye shield for image‐guided radiation therapy: An anthropomorphic phantom study

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract This study aimed to evaluate the dose‐exposure reduction effect of a crystalline lens with a bismuth eye shield using cone‐beam computed tomography (CBCT) for head image‐guided radiation therapy. The ocular surface dose of the head phantom (THRA‐1) is defined as a crystalline lens exposure dose and is measured using a radiophotoluminescence ...

Hierarchical HMM for Eye Movement Classification [PDF]

arXiv, 2020
In this work, we tackle the problem of ternary eye movement classification, which aims to separate fixations, saccades and smooth pursuits from the raw eye positional data. The efficient classification of these different types of eye movements helps to better analyze and utilize the eye tracking data. Different from the existing methods that detect eye

From 2D to 3D gamma passing rate tolerance and action limits for patient‐specific quality assurance in volumetric‐modulated arc therapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Volumetric modulated arc therapy (VMAT) requires an accurate patient‐specific quality assurance (PSQA) program. In clinical practice, this is usually performed using the γ‐index and the two‐dimensional gamma passing rate (2D %GP). A three‐dimensional (3D) index incorporating the patient anatomy could be more useful for the 3D dose ...

Your Eyes Say You're Lying: An Eye Movement Pattern Analysis for Face Familiarity and Deceptive Cognition [PDF]

arXiv, 2018
Eye movement patterns reflect human latent internal cognitive activities. We aim to discover eye movement patterns during face recognition under different cognitions of information concealing. These cognitions include the degrees of face familiarity and deception or not, namely telling the truth when observing familiar and unfamiliar faces, and ...

Automatic skin flash optimization in breast and chestwall VMAT with static angle modulated ports: Effect of HU and flash margin size on plan quality and robustness

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Skin flash is typically added to breast and chestwall plans to ensure robust target coverage in the presence of respiratory motion, anatomic changes, and small setup uncertainties. Adding skin flash in volumetric modulated arc therapy (VMAT) plans is an iterative and manual process.

Eye movement accuracy determines natural interception strategies.

Journal of Vision, 2016
Eye movements aid visual perception and guide actions such as reaching or grasping. Most previous work on eye-hand coordination has focused on saccadic eye movements.
