Augmented reality for epilepsy surgery: Examining usability and efficacy in presurgical planning.
Epileptic Disord
December 2024
Department of Neurology, Duke University Hospital, Durham, North Carolina, USA.
Objective: The aim of this paper was to visualize 3-dimensional (3-D) brain and electrode placement data for epilepsy surgery within an augmented reality (AR) environment using a wearable headset, with the ultimate goal of enhancing presurgical planning for epilepsy surgery and understanding the efficiency and utility of such a program in a clinical setting. The evaluation process for surgical intervention in epilepsy cases involves a series of extensive tests, including EEG, MRI, PET, SPECT, and fMRI. A second phase of assessment incorporates the placement of depth electrodes within the brain to record seizure activity.

Background: Distal tibial valgus deformity, though common in various medical conditions, has not been extensively studied in idiopathic flatfoot. It clinically presents as hindfoot valgus, mimicking flatfoot deformity, and requires X-rays for detection. Severity is quantified using resting calcaneal angle and standing tibio-calcaneal angles (STCA), but their prognostic value for identifying distal tibial valgus deformity remains unclear.

Optimizing the trade-offs between imaging metrics, such as normalized image log slope, telecentricity error, and best focus variation through pitch (collectively known as mask-3-dimensional (M3D) effects), is crucial to improve the throughput of the EUV lithography process. This study aims to optimize Ru/Ta bilayer photomask absorber stacks and illumination source shapes to mitigate M3D effects using mask diffraction analysis.

November 2024
From the Department of Laboratory Medicine and Pathology (Bois, Aubry, Roden, Boland, Lo, Larson, Ness, Gleichner, Peters, Layman, Yi, Maleszewski).
Context.—: Cardiac and pulmonary allograft recipients represent a unique population, frequently interacting with support groups and exhibiting intense curiosity about their pathology. Like other solid organ transplant patients, they have enduring and frequent interaction with the laboratory for routine allograft surveillance.

Background: Motor mapping allows for determining the macroscopic organization of motor circuits and corresponding motor movement representations on the cortex. Techniques such as intracortical microstimulation (ICMS) are robust, but can be time consuming and invasive, making them non-ideal for cortex-wide mapping or longitudinal studies. In contrast, optogenetic motor mapping offers a rapid and minimally invasive technique, enabling mapping with high spatiotemporal resolution.
