Three-dimensional visualization of brain tumor progression based accurate segmentation via comparative holographic projection.

PLoS ONE, 2020
We propose a new optical method based on comparative holographic projection for visual comparison between two abnormal follow-up magnetic resonance (MR) exams of glioblastoma patients to effectively visualize and assess tumor progression.

A fast marching method based back projection algorithm for photoacoustic tomography in heterogeneous media

, 2015
This paper presents a numerical study on a fast marching method based back projection reconstruction algorithm for photoacoustic tomography in heterogeneous media. Transcranial imaging is used here as a case study. To correct for the phase aberration from the heterogeneity (i.e., skull), the fast marching method is adopted to compute the phase delay ...

A Novel Approach to Extract Exact Liver Image Boundary from Abdominal CT Scan using Neutrosophic Set and Fast Marching Method

Journal of Intelligent Systems, 2019
Liver segmentation from abdominal computed tomography (CT) scan images is a complicated and challenging task. Due to the haziness in the liver pixel range, the neighboring organs of the liver have the same intensity level and existence of noise ...

Real‐time lithology identification while drilling based on drill cuttings image analysis with ensemble learning

Deep Underground Science and Engineering, EarlyView.
A lithology identification while drilling method was developed, integrating an automated cuttings sampling system, a smart drilling rig, and an ensemble learning model. Underground trials achieved 97.42% accuracy in real‐time identification of cuttings lithology and composition, enhancing hazard management and supporting unmanned drilling technology in

“I Was Just Like a Sponge, Absorbing All the Wrong Information”: Examining the Role of Social Media in Athletes' Eating Disorder and Recovery Experiences

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Within sport environments, athletes are exposed to norms that circulate narrow meanings about the body and food, contributing to the high prevalence of eating disorders (EDs). While social media can support ED recovery, it can also further constrain food‐ and body‐related messages for athletes.

The outcomes of electronic personal health records in patients with heart failure or coronary artery disease

ESC Heart Failure, Volume 12, Issue 2, Page 1464-1468, April 2025.
Abstract Background There are limited data on the efficacy of smartphone‐based personal health records (PHRs) in patients with cardiovascular disease. This study aimed to examine the processes, outcomes and challenges associated with the implementation of integrated PHRs in patients with heart failure (HF) or coronary artery disease (CAD). Methods This

Left ventricular diastolic dysfunction worsens prognosis in patients with heart failure due to dilated cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1183-1193, April 2025.
Abstract Aims The prognostic significance of left ventricular (LV) diastolic dysfunction (LVDD) severity in patients with dilated cardiomyopathy (DCM) remains uncertain. This study aimed to evaluate the association of LVDD severity and elevated left atrial pressure (eLAP) with patient outcomes in stable, non‐acutely decompensated patients with DCM ...
