Nowadays eye-tracking technologies become an inherent part of scientific researches. By the use of eye-tracking systems scientists can detect eye movements and analyze human cognitive processing of visual information for interactive and diagnostic applications. The research of eye-tracking in sports concentrates on the performance of the athletes and how it is related to perceptual function. The purpose...
Pulsed Electromagnetic Fields (PEMFs), are usually low-frequency fields with very specific wave shapes and amplitude, have been shown to accelerate wound healing and are used in adjuvant therapy. Also Pulsed Radio Frequency Energy (PRFE) is another term for this therapy that delivers electromagnetic signals to a target tissue without the intended generation of deep heat. Although the exact mechanism...
In pulse oximeter devices, the most important issue is the generation of appropriate light intensity by the light source according to the color and the composition of the target tissue. For this purpose, these devices are equipped with dedicated driver circuits that transfer different levels of DC current levels to the LEDs acting as the light sources. The current level is typically ranging from 5mA...
Falls in the elderly, due to the anatomical and physiological changes that occur with the effects of aging is common in the elderly. These injuries can negatively affect the life of the elderly. Early intervention is vital in this fall accidents. Late intervened fall accidents result in death. In this study, we propose a fall detection system that allows the detection of fall accidents and emergency...
Due to their small sizes, carbon based microelectrodes are commonly used for local and highly sensitive detection of electroactive molecules like dopamine in cell and tissues. Increasing the electrode number at the tip of a micro-electrode probe enables simultaneous detection of molecules at multiple points. In this study, probes containing single and multiple carbon fibers were fabricated, respectively...
Spontaneous potentials occur during the brain's activities. In addition, some potentials occur depending on receptor activations during the stimulated state. The aim of this study is to investigate bioelectrical changes of the brain against taste stimuli. Bioelectrical changes were recorded and measured objectively via electroencephalograhpy (EEG). Five healthy volunteers (2 females; mean age: 24...
Atmospheric pressure cold plasmas are used in sterilization, cutting and coagulation without damaging living tissues and cells. The preliminary studies on the production of the plasma pen which will allow cutting and coagulation at lower temperature than the conventional electrosurgery methods are presented. Intended power supply, pen design and manufacture are made. The results related to the first...
Analysing mouse behavior in medical experiments to determine adverse effects of medical drugs requires special expertise and it is a time consuming tedious task. Automatic scaling of facial pain mimics in mice are important for a fast and objective labeling. Although there exists a manual procedure for scaling mouse facial pain expression, a full automatic method does not exist yet. In this paper,...
In scientific area, many different studies are carried out to ensure the development of more effective and rapid wound healing method. Applied and developed several methods aims rapid wound healing with minimal discomfort to the patient which is also allow the movement of epithelial cells and to allow the regeneration of cells during to wound healing process with provided the ideal environment. It...
Expert systems based on artificial intelligence techniques help to experts by using in various areas. Especially recently they contribute to a fast and accurate diagnosis in regions that lack doctors by using in medical areas and they can provide confort for both doctors and patients, saving on time and labour-saving by reducing the time for talks between the patient and physician. Heart disease is...
Digital images obtained through medical imaging techniques are viewed using different visualization applications (methods). Also with the help of these applications, the three dimensional (3D) models of the images are created. Usually, the visualization and modelling processes are executed by medical staff, using general purpose applications. Via the same applications operation planning is made, after...
During microscopic analyses for recognition of bacteria, the prior process is to provide the optimum focusing. After the realization of focusing, due to small field o f v iew on the microscope microbiology laboratory technicians must scan without losing focusing by controlling with eye-hand to see all part of sample. This process takes a lot of time and increases making mistakes during laboratory...
Besides the material type, surface characteristics of titanium based dental implants also affect the treatment success and time. Atmospheric Cold Plasma (ACP) treatment and RGD peptide conjugation methods are applied to titanium implants for shortening the osseointegration time by increasing the surface hydrophilicty and cell adhesion rate. However the comparative effect of these two implant surface...
Varicocele is the most clinical condition which can be treated by surgery. The frequency in male is 20%. The half of infertile patient has this pathology which there is dilatation in plexus pampiniformis veins of testes. Varicocele causes increase of heat or increse of oxidative stres in seminifer tubules where they produce pathology for spermatogenesis. Low frequency magnetic fields are useful for...
Auscultation of the respiratory sounds is an inexpensive and effective method for diagnosing cardio-pulmonary disorders using lung sounds from chest and back. Nowadays, high system performances in the management of robust processes that require great attention were increased using the computer-aided analysis methods and the developments of the diagnosis system. Analysis of the respiratory sounds with...
In this study, temperature distribution of human brain has calculated via Bio-heat Model. Head geometry, to be used in analysis, obtained from converting 2D stack image -which taken via medical imaging machine (MRI, CTI) and can be found in Brainweb- to 3D mesh struct. 3 layered geometry has been created as outer skin, skull and brain. For each layer, tissue perfusion rate, metabolic heat generation...
In this study, variation of contrast-noise ratio and mean glanduler dose have been evaluated for increasing breast thickness in mammographic application. Measurements were carried out in the Siemens Mammomat Inspiration full-field digital mammography unit by using polymethyl-methacrylate phantom (PMMA) in order to simulate different breast thicknesses. Contrast-to-Noise Ratio (CNR) and Mean Glanduler...
