Mechanomyographic amplitude and frequency responses during dynamic muscle actions: a comprehensive review
Source, 2 hours ago
The purpose of this review is to examine the literature that has investigated mechanomyographic (MMG) amplitude and frequency responses during dynamic muscle actions. To date, the majority of MMG research has focused on isometric muscle actions. Recent studies, however, have examined the MMG time an...
Axial stent strut angle influences wall shear stress after stent implantation: analysis using 3D computational fluid dynamics models of stent foreshortening
Source, 2 hours ago
IntroductionThe success of vascular stents in the restoration of blood flow is limited by restenosis. Recent data generated from computational fluid dynamics (CFD) models suggest that the vascular geometry created by an implanted stent causes local alterations in wall shear stress (WSS) that are ass...
Evaluation of the effect of stent strut profile on shear stress distribution using statistical moments
Source, 2 hours ago
Background: In-stent restenosis rates have been closely linked to the wall shear stress distribution within a stented arterial segment, which in turn is a function of stent design. Unfortunately, evaluation of hemodynamic performance can only be evaluated with long term clinical trials. In this work...
Performance of the Emotiv Epoc headset for P300-based applications
Source, 2 hours ago
Background: For two decades, EEG-based Brain-Computer Interface (BCI) systems have been widely studied in research labs. Now, researchers want to consider out-of-the-lab applications and make this technology available to everybody. However, medical-grade EEG recording devices are still much too expe...
Challenges, issues and trends in fall detection systems
Source, 2 hours ago
Since falls are a major public health problem among older people, the number of systems aimed at detecting them has increased dramatically over recent years. This work presents an extensive literature review of fall detection systems, including comparisons among various kinds of studies. It aims to ...
Biological effects of exposure to magnetic resonance imaging: an overview
Source, 2 hours ago
The literature on biological effects of magnetic and electromagnetic fields commonly utilized in magnetic resonance imaging systems is surveyed here. After an introduction on the basic principles of magnetic resonance imaging and the electric and magnetic properties of biological tissues, the basic ...
How smartphones are changing the face of mobile and participatory healthcare: an overview, with example from eCAALYX
Source, 2 hours ago
The latest generation of smartphones are increasingly viewed as handheld computers rather than as phones, due to their powerful on-board computing capability, capacious memories, large screens and open operating systems that encourage application development. This paper provides a brief state-of-the...
Telemedicine supported by Augmented Reality: an interactive guide for untrained people in performing an ECG test
Source, December 10, 2014
Background: In many telemedicine applications, the correct use of medical device at the point of need is essential to provide an appropriate service. Some applications may require untrained people to interact with medical devices and patients: care delivery in transportation, military actions, home ...
Dual-/tri-apodization techniques for high frequency ultrasound imaging: a simulation study
Source, October 31, 2014
Background: In the ultrasound B-mode (Brightness-mode) imaging, high side-lobe level reduces contrast to noise ratio (CNR). A linear apodization scheme by using the window function can suppress the side-lobe level while the main-lobe width is increased resulting in degraded lateral resolution. In or...
Design of a microscopic electrical impedance tomography system for 3D continuous non-destructive monitoring of tissue culture
Source, October 25, 2014
Background: Non-destructive continuous monitoring of regenerative tissue is required throughout the entire period of in vitro tissue culture. Microscopic electrical impedance tomography (micro-EIT) has the potential to monitor the physiological state of tissues by forming three-dimensional images of...
