Electrical Impedance Imaging System based on FPGAs to enable Flexibility and Interoperability
Source, 4 hours ago
Background: Modern EIT systems require simultaneously operating multiple functions for flexibility, interoperability,and clinical applicability. To implement versatile functions, expandable design and implementationtools are needed. On the other hand, it is necessary to develop an ASIC-based EIT sys...
Identification and monitoring of brain activity based on stochastic relevance analysis of short--time EEG rhythms
Source, August 28, 2014
Background: The extraction of physiological rhythms fromelectroencephalography (EEG) data and their automated analyses are extensively studied in clinical monitoring, to find traces of interictal/ictal states of epilepsy. Methods: Because brain wave rhythms in normal and interictal/ictal events, dif...
Reconstruction of Freehand 3D Ultrasound based on Kernel Regression
Source, August 28, 2014
IntroductionFreehand three-dimensional (3D) ultrasound has the advantages of flexibility for allowing cliniciansto manipulate the ultrasound probe over the examined body surface with less constraint in comparisonwith other scanning protocols. Thus it is widely used in clinical diagnose and image-gui...
Thermal, creep-recovery and viscoelastic behavior of high density polyethylene/ hydroxyapatite nano particles for bone substitutes: effects of gamma radiation
Source, August 28, 2014
Background: High Density Polyethylene (HDPE) is one of the most often used polymers in biomedical applications. The limitations of HDPE are its visco-elastic behavior, low modulus and poor bioactivity. To improve HDPE properties, HA nanoparticles can be added to form polymer composite that can be us...
Accuracy assessment of Tri-plane B-mode ultrasound for non-invasive 3D kinematic analysis of knee joints
Source, August 26, 2014
Background: Currently the clinical standard for measuring the motion of the bones in knee joints with sufficient precision involves implanting tantalum beads into the bones. These beads appear as high intensity features in radiographs and can be used for precise kinematic measurements. This procedur...

Theoretical optimization of the removal of cryoprotective agents using a dilution-filtration system
Source, August 21, 2014
Background: In the cryopreservation of blood, removing cryoprotectants from the cryopreserved blood safely and effectively is always being focused on. In our previous work, a dilution-filtration system was proposed to achieve the efficient clearance of cryoprotectants from the cryopreserved blood.Me...
Compressed-sensing-based fluorescence molecular tomographic image reconstruction with grouped sources
Source, August 20, 2014
Background: Although the quality of reconstructed results can be improved with the increment of the number of measurements, the scale of the matrices involved in the reconstruction of fluorescence molecular tomography (FMT) will become larger, which leads to the poor efficiency of the process of tom...
Prototype of biliary drug-eluting stent with photodynamic and chemotherapy using electrospinning
Source, August 19, 2014
Background: The combination of biliary stent with photodynamic and chemotherapy seemed to be a beneficial palliative treatment of unresectable cholangiocarcinoma. However, by intravenous delivery to the target tumor the distribution of the drug had its limitations and caused serious side effect on n...
A photoacoustic image reconstruction method using total variation and nonconvex optimization
Source, August 16, 2014
Background: In photoacoustic imaging (PAI), the reduction of scanning time is a major concern for PAI in practice. A popular strategy is to reconstruct the image from the sparse-view sampling data. However, the insufficient data leads to reconstruction quality deteriorating. Therefore, it is very im...
