In this paper, we investigate the behavior of state-of-the-art pattern matching algorithms when applied to electromyographic data recorded during 21 days. To this end, we compare the five classification techniques k-nearest-neighbor, linear discriminant analysis, decision trees, artificial neural networks and support vector machines. We provide all classifiers with features extracted from electromyographic signals taken from forearm muscle contractions, and try to recognize ten different hand movements. The major result of our investigation is that the classification accuracy of initially trained pattern matching algorithms might degrade on subsequent data indicating variations in the electromyographic signals over time.

An ultra-low-power 1KS/s 8-bit current mode successive approximation (SAR) analog-digital converter (ADC) for pacemakers is presented. The proposed system architecture is designed to achieve a small chip area and ultra low power consumption by using current mode operation. The circuit is realized in a IBM 0.13μm CMOS technology. The simulated power consumption is 225 nW corresponding to a figure of merit of 0.657pJ/conversion-step while operating from a 1 V supply. The power consumption is one of the lowest reported.

The human brain possesses a highly structured surface. A quantitative examination of the cortical surface is of particular interest for many questions, e.g. the investigation the relation between the spatial frequencies of cortical surfaces and spatial frequencies within Electroencephalogram and the analysis of changes of the structure of the human brain caused by diseases. In this paper a Fourier analysis approach to investigate the spatial spectrum of contour data of the cortical surface is introduced. The method was validated using artificial data with known spatial spectrum and employed to investigate the spatial frequencies of the cortical surface of a human subject. © 2010 IEEE.

Heart rate variability (HRV) is a very useful signal to investigate the activity of the autonomic nervous system (ANS), which affects and the heart function. Constructing a mathematical model for producing artificial HRV signal is needed to get a conceptual understanding of how ANS controls the heart rate (HR). The integral pulse frequency modulation (IPFM) structure is employed in this paper to model the sino-atrial node (SAN). Considering the complexity and nonlinear dynamics in the real HRV signal, a chaotic input is used in the proposed model. Instead of using a fixed threshold in IPFM model as in most previous works, we applied an appropriate variable signal, which has nonlinear chaotic dynamics. After running the model, the power spectrum of the output signal is extracted, which was then followed by calculating the nonlinear characteristics. The results were closely correlated with the real data, which confirm the effectiveness of the proposed model.

Many brain events and disorders can be detected by analyzing electroencephalograms (EEGs). Also the availability of quantitative biological markers that are correlated with qualitative psychiatric phenotypes helps us to utilize automated methods to diagnose and classify these phenotypes. One such a psychiatric phenotype is alcoholism. In this study a method to select an optimal subset of EEG channels for the purpose of practical classification of alcohol abusers from normal subjects is proposed, which is based on combination of model-based spectral analysis and correlation matrices. The EEG signals were recorded when the subjects were represented with single trial visual stimuli. The proposed method proved successful in selecting an optimum number of channels which achieved acceptable average classification accuracy.

Nervous system conveys information by electrical signals called `spikes', therefore, spikes detection and sorting are challenging topics in the neural data processing. The principal component analysis (PCA) is a convenient tool for clustering spikes; however it has some disadvantages for closely shaped and overlapped spikes. For such the cases, an algorithm based on the combination of the principal component analysis and undecimated wavelet transform, is proposed to enhance the cluster formation from the spikes mapping. These results indicate that the principal component analysis used in combination with the undecimated wavelet has a better performance in the spike sorting. This can lead to more compact and separate clusters in comparison with the PCA clustering and more efficient spike sorting.

In this paper we present a semi-automatic method for femoral bone positioning after 3D image reconstruction from Computed Tomography images. This serves as grounding for the definition of strict axial, longitudinal and anterior-posterior views, overcoming the problem of patient positioning biases in 2D femoral bone measuring methods. After the bone reconstruction is aligned to a standard reference frame, new tomographic slices can be generated, on which unbiased measures may be taken. This could allow not only accurate inter-patient comparisons but also intra-patient comparisons, i.e., comparisons of images of the same patient taken at different times. This method could enable medical doctors to diagnose and follow up several bone deformities more easily.

A surgical technique currently used in the treatment of Abdominal Aortic Aneurysms (AAA) is the Endovascular Aneurysm Repair (EVAR). This minimally invasive procedure involves inserting a prosthesis in the aortic vessel that excludes the aneurysm from the bloodstream. The stent, once in place acts as a false lumen for the blood current to travel down, and not into the surrounding aneurysm sac. This procedure, therefore, immediately takes the pressure off the aneurysm, which thromboses itself after some time. Nevertheless, in a long term perspective, different complications such as prosthesis displacement or bloodstream leaks into or from the aneurysmatic bulge (endoleaks) could appear causing a pressure elevation and, as a result, increasing the danger of rupture. The purpose of this work is to explore the application of image registration techniques to the visual detection of changes in the thrombus in order to assess the evolution of the aneurysm. Prior to registration, both the lumen and the thrombus are segmented © 2010 Springer-Verlag.

A number of ultrasound methods are available for medical imaging. Fundamental imaging uses the echoes from the same spectral band as the transmitted pulse. Tissue harmonic imaging (THI) utilizes frequencies at multiple(s) of the fundamental and effectively suppresses reverberations, and off-axis and near-field artifacts. Two types of THI comprise secondand superharmonic imaging (SHI). The former uses the second harmonic of the echoes and the latter combines the third to fifth harmonics. Clinical research showed that the optimal transmit frequency for fundamental and second harmonic cardiac imaging is 3.5 and 1.8 MHz respectively. As the level of the harmonics is determined by a balance of nonlinear propagation and attenuation, the optimal frequency for SHI is expected to be lower. The first goal of this study was to investigate the optimal transmit frequency for SHI by simulating the entire imaging chain based on an adapted SONAR equation. Two simulation cases are examined: the first uses cardiac tissue properties and the second is based on a mix of 50% cardiac tissue and 50% blood. Using the SONAR equation the signal-to-noise ratio (SNR) for the second to fifth harmonics was computed up to 15 cm for 1 2.5 MHz transmit frequencies. The transducer's transmit and receive transfer was modeled, as well as its noise. The adaptation included nonlinear forward propagation calculated with axisymmetric KZK, the backpropagation was linear. The highest frequency yielding a 30 dB dynamic range at the required imaging depth was assumed optimal. The second goal of this study was to compare the beams produced by optimal fundamental, second and SHI for cardiac applications. To this end we used a 3D KZK implementation for rectangular apertures. The optimal transmit frequency for SHI was 1.0 1.2 MHz at 13 cm using cardiac tissue properties, this increased to 1.7 MHz if the properties of the cardiac tissue/blood mix were used. The -6 dB lateral beam width of the optimal fundamental, s
