Image analysis and processing methods in verifying the correctness of performing low-invasive esthetic medical procedures
Background: Efficacy and safety of various treatments using fractional laser or radiofrequency depend, to a large extent, on precise movement of equipment head across the patient''s skin. In addition, they both depend on uniform distribution of emitted pulses throughout the treated skin area. The pu...
Improvement of classification accuracy in a phase-tagged steady-state visual evoked potential-based brain computer interface using multiclass support vector mac...
Background: Brain computer interface (BCI) is an emerging technology for paralyzed patients to communicate with external environments. Among current BCIs, the steady-state visual evoked potential (SSVEP)-based BCI has drawn great attention due to its characteristics of easy preparation, high informa...
An optical tracker based robot registration and servoing method for ultrasound guided percutaneous renal access
Background: Robot-assisted needle steering facilitates the percutaneous renal access (PRA) for their accuracy and consistency over manual operation. However, inaccurate image-robot correspondence and uncertainties in robot parameters make the needle track deviate from the intrarenal target. This pap...
Performance assessment in brain-computer interface-based augmentative and alternative communication
A large number of incommensurable metrics are currently used to report the performance of brain-computer interfaces (BCI) used for augmentative and alterative communication (AAC). The lack of standard metrics precludes the comparison of different BCI-based AAC systems, hindering rapid growth and dev...
Methods of measuring the iridocorneal angle in tomographic images of the anterior segment of the eye
IntroductionThis paper presents the problem of automatic measurement of the iridocorneal angle in tomographic images of the anterior segment of the eye. It includes the results of the comparison of well-known methods for measuring the iridocorneal angle with new methods, proposed in this paper. All ...
Comparisons of maximum deformation and failure forces at the implant--abutment interface of titanium implants between titanium-alloy and zirconia abutments with...
Background: Zirconia materials are known for their optimal aesthetics, but they are brittle, and concerns remain about whether their mechanical properties are sufficient for withstanding the forces exerted in the oral cavity. Therefore, this study compared the maximum deformation and failure forces ...
Classification of emotional states from electrocardiogram signals: a non-linear approach based on hurst
Background: Identifying the emotional state is helpful in applications involving patients with autism and other intellectual disabilities; computer-based training, human computer interaction etc. Electrocardiogram (ECG) signals, being an activity of the autonomous nervous system (ANS), reflect the u...
Effect of pressure and padding on motion artifact of textile electrodes
Background: With the aging population and rising healthcare costs, wearable monitoring is gaining importance. The motion artifact affecting dry electrodes is one of the main challenges preventing the widespread use of wearable monitoring systems. In this paper we investigate the motion artifact and ...
Neurovascular coupling: in vivo optical techniques for functional brain imaging
Optical imaging techniques reflect different biochemical processes in the brain, which is closely related with neural activity. Scientists and clinicians employ a variety of optical imaging technologies to visualize and study the relationship between neurons, glial cells and blood vessels. In this p...
