  • AUTOMATIC SEGMENTATION OF BREAST TISSUE THERMAL IMAGES
    • Authors: Zeinab Heidari, Mehrdad Dadgostar, Zahra Einalou
      Abstract: Biomedical Engineering: Applications, Basis and Communications, Volume 30, Issue 03, June 2018.
      Breast cancer is one of the main causes of women’s death. Thermal breast imaging is one the non-invasive method for cancer at early stage diagnosis. In contrast to mammography this method is cheap and painless and it can be used during pregnancy while ionized beams are not used. Specialists are seeking new ways to diagnose the cancer in early stages. Segmentation of the breast tissue is one of the most indispensable stages in most of the cancer diagnosis methods. By the advancement of infrared precise cameras, new and fast computers and nouvelle image processing approaches, it is feasible to use thermal imaging for diagnosis of breast cancer at early stages. Since the breast form is different in individuals, image segmentation is a hard task and semi-automatic or manual methods are usual in investigations. In this research the image data base of DMR-IR has been utilized and a now automatic approach has been proposed which does not need learning. Data were included 159 gray images used by dynamic protocol (132 healthy and 27 patients). In this study, by combination of different image processing methods, the segmentation of thermal images of the breast tissues have been completed automatically and results show the proper performance of recommended method.

  • A BIOABSORBABLE, DEGRADABLE STENT WITH A DRUG RELEASE SYSTEM
    • Authors: Si W. Liu, Ching-Sung Weng, Shih-Ming Wang, Wei-Jie Wang, Ming-Chen Wang
      Abstract: Biomedical Engineering: Applications, Basis and Communications, Volume 30, Issue 03, June 2018.
      The aim of this study was to develop a bioabsorbable, degradable stent for drug storage that can be produced rapidly. A stent with a length of 28[math]mm and a diameter of 6[math]mm was generated by injecting polycaprolactone (PCL) (PubChem CID:6452583) into a mold created using a toggle-type microtool machine. Micropores of 0.5[math]mm diameter and 0.6[math]mm depth were created on stents. A stent had 54 pores, and each pore had a storage volume of 0.1175[math]c3. To determine the optimal PCL concentration for stent construction, stents of three PCL concentrations (20%, 25%, and 30%) were fabricated in the experiment, and the material and chemical properties of the stents were determined. In addition, four proportions of PCL:PLGA (10:0, 8:2, 5:5, 0:10) were tested, and the corresponding pore degradation time was employed as a reference parameter for controlling the amount of drug release in the stent design. With an increase in PCL concentration from 20% to 30%, the load increased from 39.718 to 63.5[math]N. The stent with 25% PCL concentration exhibited optimal surface roughness ([math][math]nm). Finally, scanning electron microscopy indicated that the surface of the material with 25% PCL concentration did not contain any fractures and exhibited planar evenness. The results demonstrate the development of a bioabsorbable, degradable stent that can be applied in vascular surgery.

  • A COMPUTATIONAL FRAMEWORK TO DISCRIMINATE DIFFERENT ANESTHESIA STATES FROM
           EEG SIGNAL
    • Authors: Seyyed Abed hosseini
      Abstract: Biomedical Engineering: Applications, Basis and Communications, Ahead of Print.
      This paper develops a computational framework to classify different anesthesia states, including awake, moderate anesthesia, and general anesthesia, using electroencephalography (EEG) signal. The proposed framework presents data gathering; preprocessing; appropriate selection of window length by genetic algorithm (GA); feature extraction by approximate entropy (ApEn), Petrosian fractal dimension (PFD), Hurst exponent (HE), largest Lyapunov exponent (LLE), Lempel-Ziv complexity (LZC), correlation dimension (CD), and Daubechies wavelet coefficients; feature normalization; feature selection by non-negative sparse principal component analysis (NSPCA); and classification by radial basis function (RBF) neural network. Because of the small number of samples, a five-fold cross-validation approach is used to validate the results. A GA is used to select that by observing an interval of 2.7[math]s for further assessment. This paper assessed superior features, such as LZC, ApEn, PFD, HE, the mean value of wavelet coefficients for the beta band, and LLE. The results indicate that the proposed framework can classify different anesthesia states, including awake, moderate anesthesia, and general anesthesia, with an accuracy of 92.07%, 96.18%, and 93.42%, respectively. Therefore, the proposed framework can discriminate different anesthesia states with an average accuracy of 93.89%. Finally, the proposed framework provided a facilitative representation of the brain’s behavior in different states of anesthesia.

  • BLUETOOTH-BASED WIRELESS DIGITAL STETHOSCOPE WITH MOBILE INTEGRATION
    • Authors: Derek Kweku Degbedzui, Michael Tetteh, Elsie Effah Kaufmann, Godfrey A. Mills
      Abstract: Biomedical Engineering: Applications, Basis and Communications, Ahead of Print.
      Acoustic stethoscopes are used to monitor signals from patients. Incidentally, the connecting tube between the chest-piece and the ear-piece of common stethoscopes is known to serve as a medium for transmitting pathogens from patients to physicians or from one patient to another patient. This work presents a wireless stethoscope design with mobile integration that transmits heart sounds to mobile devices for evaluation and analysis, thus, eliminates the connecting tube. This is an extension of the previous work that presented the proof of concept of a wireless stethoscope with Bluetooth transmission. In this work, however, the chest-piece of the traditional stethoscope is integrated with microcontroller unit and Bluetooth communication device. Captured signals are processed and transmitted wirelessly to a mobile device with interface application software for recording, listening and visual display of waveforms. Following numerical simulation, a prototype was developed. Testing conducted on the prototype device using a class 2 Bluetooth device with 4[math]dBm transmission power showed good quality received signals when the mobile device was placed 20[math]m within indoor environments and 42[math]m in open-space outdoor environment, beyond which degradation in quality occurs. It is worth pointing out that a smart Bluetooth device with high transmission range and data speed may produce much longer operating distance. Hence, for applications that require operating ranges beyond 50[math]m, smart Bluetooth devices may be well suited for such systems. This system may serve as the means for monitoring patients from remote locations particularly quarantine units and can also be useful for training health personnel through broadcasting of recorded signals for analysis and evaluation by members of a medical team.

  • HYBRID BRAIN–COMPUTER INTERFACE PARADIGM — A STUDY
    • Authors: Rajesh Singla
      Abstract: Biomedical Engineering: Applications, Basis and Communications, Ahead of Print.
      The advancements in the field of brain–computer interface (BCI) are driven by the underlying motive of improving quality of life for both healthy as well as locked in subjects. Since BCI’s are based on the response of the human brain to training or external stimuli, the improvement in terms of performance can be achieved by either enhancing the subject training procedure or by improving the external stimuli to produce maximized event related potential (ERP). P300 and steady-state visually evoked potential (SSVEP) approaches have been the most common paradigms used for stimulus-based BCI’s world over. But recently, a large number of researchers are facing a problem of BCI illiteracy in subjects, where some of the subjects showed ineffective results while training with these BCI as independent stimuli. The concept of hybrid brain–computer interface (hBCI) is a step towards eradicating this problem. Our research deals with external stimuli-based ERP generation where we discuss and compare with experimentation, three different options of visual stimulus: conventional SSVEP stimulus, P300-SSVEP hybrid stimulus, distinct target colors for P300-SSVEP-based hybrid stimulus. This paper introduces a novel hBCI paradigm and discusses the validation of improved results by comparing with the already existing stimuli options. The parameters of comparison that were considered to validate our proposal were decision accuracy (Acc), information transfer rate (ITR) and false activation rate (FAR).

  • SEGMENTATION AND CLASSIFICATION OF ISCHEMIC STROKE USING OPTIMIZED
           FEATURES IN BRAIN MRI
    • Authors: Asit Subudhi, Sanatnu Sahoo, Pradyut Biswal, Sukanta Sabut
      Abstract: Biomedical Engineering: Applications, Basis and Communications, Ahead of Print.
      Detection of ischemic stroke using brain magnetic resonance imaging (MRI) images is vital and a challenging task in clinical practice. We propose a novel method based on optimization technique to identify stroke lesion in diffusion-weighted imaging (DWI) MRI sequences of the brain. The algorithm was tested in a specific slice having large area of stroke region from a series of 292 real-time images obtained from different stroke affected subjects from IMS and SUM Hospital. The proposed method consists of pre-processing, segmentation, extraction of important features and classification of stroke type. The particle swarm optimization (PSO) and Darwinian particle swarm optimization (DPSO) algorithms were applied in segmenting the stroke lesions. The important features were extracted with the gray-level co-occurrence matrix (GLCM) algorithm and in decision making process, the feature set is classified into three types of stroke according to The Oxfordshire Community Stroke Project (OCSP) classification using support vector machine (SVM) classifier. The lesion area was segmented effectively with DPSO process with classification weighted accuracy of 90.23%, which is higher than PSO method having weighted accuracy of 87.34%. Similarly, the values of different measured parameters were high in DPSO technique, the computational time was also higher in DPSO method for segmenting the stroke lesions. These results confirm that the DPSO-based approach with SVM classifier is an effective way to identify the decision making process of ischemic stroke lesion in MRI images of the brain.

  • FATIGUE DETECTION USING THE STRENGTH OF DOMINANT EEG SOURCE: A BEAMFORMING
           APPROACH
    • Authors: Samaneh Kouchaki, Reza Boostani, Fatemeh Razavipour
      Abstract: Biomedical Engineering: Applications, Basis and Communications, Ahead of Print.
      It is evident that the electroencephalogram (EEG) rhythms are slightly changed when the efficacy of mental activity declines (brain fatigue). Nonetheless, this slight change is not easily detectable by the so far suggested scalp EEG features. The goal of this paper is to propose an EEG-based biomarker, which has a congruity to the mental fatigue variation to detect the transition from non-fatigue to the fatigue mental state. The strength of the dominant EEG source, extracted by minimum variance beamformer (MVB), is proposed here as a discriminative feature to remarkably classify the two mental states. To assess the proposed scheme, EEG signals of 17 volunteers were recorded via 32 electrodes before and after taking an exhausting mental exam (3[math]h) and the extracted EEG features were labeled as non-fatigue and fatigue, respectively. After removing the eye-blink effect, the proposed feature along with the conventional EEG features were extracted from the recorded EEGs and then applied to support vector machine (SVM) and 1-nearest neighbor (1NN) classifiers in order to differentiate these two mental states. The best result is achieved by applying the proposed feature to the SVM classifier providing 97.06% classification accuracy which is significantly ([math]) superior to its counter parts.

  • IMPROVEMENT OF THE PERFORMANCE OF FINGERPRINT VERIFICATION USING A
           COMBINATORIAL APPROACH
    • Authors: Fatemeh Alimardani, Reza Boostani
      Abstract: Biomedical Engineering: Applications, Basis and Communications, Ahead of Print.
      Fingerprint verification systems have attracted much attention in secure organizations; however, conventional methods still suffer from unconvincing recognition rate for noisy fingerprint images. To design a robust verification system, in this paper, wavelet and contourlet transforms (CTS) were suggested as efficient feature extraction techniques to elicit a coverall set of descriptive features to characterize fingerprint images. Contourlet coefficients capture the smooth contours of fingerprints while wavelet coefficients reveal its rough details. Due to the high dimensionality of the elicited features, across group variance (AGV), greedy overall relevancy (GOR) and Davis–Bouldin fast feature reduction (DB-FFR) methods were adopted to remove the redundant features. These features were applied to three different classifiers including Boosting Direct Linear Discriminant Analysis (BDLDA), Support Vector Machine (SVM) and Modified Nearest Neighbor (MNN). The proposed method along with state-of-the-art methods were evaluated, over the FVC2004 dataset, in terms of genuine acceptance rate (GAR), false acceptance rate (FAR) and equal error rate (EER). The features selected by AGV were the most significant ones and provided 95.12% GAR. Applying the selected features, by the GOR method, to the modified nearest neighbor, resulted in average EER of [math]%, which outperformed the compared methods. The comparative results imply the statistical superiority ([math]) of the proposed approach compared to the counterparts.
