Telemedicine supported by Augmented Reality: an interactive guide for untrained people in performing an ECG test
Source, November 21, 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 ...
A numerical study of the effect of varied blood pressure on the stability of carotid atherosclerotic plaque
Source, November 20, 2014
Background: Blood pressure (BP) is associated with early atherosclerosis and plaque rupture because the BP variability can significantly affect the blood flow velocity and shear stress over the plaque. However, the mechanical response of BP variability to the plaque remains unclear. Therefore, we in...
An adaptive spinal-like controller: tunable biomimetic behavior for a robotic limb
Source, November 19, 2014
Background: Spinal-like regulators have recently been shown to support complex behavioral patterns during volitional goal-oriented reaching paradigms. We use an interpretation of the adaptive spinal-like controller as inspiration for the development of a controller for a robotic limb. It will be dem...
Impedance spectroscopy of changes in skin-electrode impedance induced by motion
Source, November 17, 2014
Background: The motion artifact is an ever-present challenge in the mobile monitoring of surface potentials. Skin-electrode impedance is investigated as an input parameter to detect the motion artifact and to reduce it using various methods. However, the impact of the used impedance measurement freq...
Determination of detection depth of optical probe in pedicle screw measurement device
Source, October 31, 2014
Background: There is a high probability of accidental perforation of the vertebral pedicle wall in pedicle screw insertion surgery. A pedicle screw (PS) measurement device with an optical probe has been reported to send out a warning signal before the PS tip breaking the vertebral pedicle wall. Meth...
Bright field microscopic cells counting method for BEVS using nonlinear convergence index sliding band filter
Source, October 23, 2014
Background: The Baculovirus Expression Vector System (BEVS) is a very popular expression vector system in gene engineering. An effective host cell line cultivation protocol can facilitate the baculovirus preparation and following experiments. However, the counting of the number of host cells in the ...
Estimation of pelvis kinematics in level walking based on a single inertial sensor positioned close to the sacrum: validation on healthy subjects with stereopho...
Source, October 21, 2014
Background: Kinematics measures from inertial sensors have a value in the clinical assessment of pathological gait, to track quantitatively the outcome of interventions and rehabilitation programs. To become a standard tool for clinicians, it is necessary to evaluate their capability to provide reli...
An equivalent circuit model for onset and offset exercise response
Source, October 18, 2014
Background: The switching exercise (e.g., Interval Training) has been a commonly used exercise protocol nowadaysfor the enhancement of exerciser''s cardiovascular fitness. The current difficulty for simulating humanonset and offset exercise responses regarding the switching exercise is to ensure the...
Prototype development of an electrical impedance based simultaneous respiratory and cardiac monitoring system for gated radiotherapy
Source, October 14, 2014
Background: In radiotherapy, temporary translocations of the internal organs and tumor induced by respiratory and cardiac activities can undesirably lead to significantly lower radiation dose on the targeted tumor but more harmful radiation on surrounding healthy tissues. Respiratory and cardiac gat...
Dual-/tri-apodization techniques for high frequency ultrasound imaging: a simulation study
Source, October 10, 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...
