A Convergent Pathway for Stimulation‐Induced Dyskinesia Following Deep Brain Stimulation

open access: yesMovement Disorders, EarlyView.
Abstract Background Stimulation‐induced dyskinesias (SID) from deep brain stimulation (DBS) of the subthalamic nucleus (STN) and globus pallidus internus (GPi) are uncommon; however, they are increasingly recognized. Once considered transient and indicative of effective neuromodulation, SID are now seen as potential therapy‐limiting side effects, akin ...

Two Types of q$$ q $$‐Gaussian Distributions Used to Study the Diffusion in a Finite Region

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this work, we explore both the ordinary q$$ q $$‐Gaussian distribution and a new one defined here, determining both their mean and variance, and we use them to construct solutions of the q$$ q $$‐deformed diffusion differential equation. This approach allows us to realize that the standard deviation of the distribution must be a function of

Deep learning‐based estimation of respiration‐induced deformation from surface motion: A proof‐of‐concept study on 4D thoracic image synthesis

open access: yesMedical Physics, EarlyView.
Abstract Background Four‐dimension computed tomography (4D‐CT) provides important respiration‐related information for thoracic radiotherapy. Its quality is challenged by various respiratory patterns. Its acquisition gives rise to the risk of higher radiation exposure.

Deep learning‐based cone‐beam CT motion compensation with single‐view temporal resolution

open access: yesMedical Physics, EarlyView.
Abstract Background Cone‐beam CT (CBCT) scans that are affected by motion often require motion compensation to reduce artifacts or to reconstruct 4D (3D+time) representations of the patient. To do so, most existing strategies rely on some sort of gating strategy that sorts the acquired projections into motion bins.

Groupwise image registration with edge‐based loss for low‐SNR cardiac MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The purpose of this study is to perform image registration and averaging of multiple free‐breathing single‐shot cardiac images, where the individual images may have a low signal‐to‐noise ratio (SNR). Methods To address low SNR encountered in single‐shot imaging, especially at low field strengths, we propose a fast deep learning (DL ...
