Effect of Contour Shape of Nervous System Electromagnetic Stimulation Coils on the Induced Electrical Field Distribution
Source, 16 hours ago
Background: Electromagnetic stimulation of the nervous system has the advantage of reduced discomfort in activating nerves. For brain structures stimulation, it has become a clinically accepted modality. Coil designs usually consider factors such as optimization of induced power, focussing, field sh...
Oscillometric measurement of systolic and diastolic blood pressures validated in a physiologic mathematical model
Source, 16 hours ago
Background: The oscillometric method of measuring blood pressure with an automated cuff yields valid estimates of mean pressure but questionable estimates of systolic and diastolic pressures. Existing algorithms are sensitive to differences in pulse pressure and artery stiffness. Some are closely gu...
Performance of the Emotiv Epoc headset for P300-based applications
Source, 16 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...
Biological effects of exposure to magnetic resonance imaging: an overview
Source, 16 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 ...
Automatic analysis of 2D polyacrylamide gels in the diagnosis of DNA polymorphisms
Source, 16 hours ago
IntroductionThe analysis of polyacrylamide gels is currently carried out manually or automatically. In the automatic method, there are limitations related to the acceptable degree of distortion of lane and band continuity. The available software cannot deal satisfactorily with this type of situation...
Challenges, issues and trends in fall detection systems
Source, 16 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 ...
How smartphones are changing the face of mobile and participatory healthcare: an overview, with example from eCAALYX
Source, 16 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...
Influence of the measurement method of features in ultrasound images of the thyroid in the diagnosis of Hashimoto''s disease
Source, 16 hours ago
IntroductionThis paper shows the influence of a measurement method of features in the diagnosis of Hashimoto's disease. Sensitivity of the algorithm to changes in the parameters of the ROI, namely shift, resizing and rotation, has been presented. The obtained results were also compared to the method...
Content-independent embedding scheme for multi-modal medical image watermarking
Source, March 01, 2015
Background: As the increasing adoption of information technology continues to offer better distant medical services, the distribution of, and remote access to digital medical images over public networks continues to grow significantly. Such use of medical images raises serious concerns for their con...
A comparative analysis of swallowing accelerometry and sounds during saliva swallows
Source, February 08, 2015
Background: Accelerometry (the measurement of vibrations) and auscultation (the measurement of sounds) are both non-invasive techniques that have been explored for their potential to detect abnormalities in swallowing. The differences between these techniques and the information they capture about s...
