Today, wireless technologies are being used in almost every area of our lives. Especially in the field of health, the use of wireless technologies is increasing every day. The most important advantage of using wireless communication in biomedical area is that health services can be provided outside health facilities. In addition to this, long and troublesome follow-up of the patient; The patient's...
UF-EMG test, in which non-invasive uroflowmetry (UF) and electromyography (EMG) signals are simultaneously recorded, is frequently used in children diagnosed with lower urinary tract dysfunction disease (AUSD) and its treatment. In the literature, independent (single) UF signals and integrated (dual) UF-EMG signals are graded many times but there is no classification study of UF-EMG integrated signals...
The heart, which is at the head of the vital organs, carries the oxygen and nutrients needed for the cells of the human body to the cells by being strained and loosened through the veins surrounding the body. HR-heart rate measurement is an important consideration for human health. The HR increase and decrease also indicate that the individual is subject to any disease and physiological effects as...
Resting State-fMRI represents an emerging and powerful tool to explore brain functional connectivity (FC) changes associated with neurologic disorders. Compared to activation/task-related fMRI, Resting State fMRI has the advantages such as (i) Blood oxygen level dependent (BOLD) fMRI signals are self-generated and independent of subject's performance during the task and (ii) a single dataset is sufficient...
There is an increasing demand in the society for an accurate cost sensitive compact biosensor. This is due to the fact that this kind of biosensor can slightly decrease the diagnosis period of diseases, which has major importance on the treatment period. Also it would not require facilities or expertise which is only available in hospital laboratories. Optical biosensors can offer very sensitive and...
Early detection and monitoring of heart diseases increase human quality of life and this can prevent negative consequences. It is even more important because it can prevent sudden deaths. In today's technology, these operations can be done with telemedicine systems. In this work, appropriate methods have been proposed for telemedicine systems. The proposed system is of two classes and is based on...
Detection of ST segment depression, elevation, or an arrhythmia in the ECG signal is very important for the early detection of a myocardial infarction. In this study, an algorithm based on Zhao-Atlas-Mark time-frequency distribution was developed in order to early detection of ST segment depression, elevation or arrhythmia on ECG signal. The performance evaluation of the algorithm was performedon...
In the study, it was aimed to investigate the bactericidal activity of antimicrobial photodynamic therapy (aPDT) performed on in-vitro conditions with novel cationic-porphyrin derivatives (CPDs) on multidrug resistant E. coli. In aPDT experiments performed with different concentrations of photosensitizer and different energy densities, 99.9999% or more decrease in bacterial survival was detected....
In recent years, polysaccharide biopolymers have attracted great interest due to being more hydrophilic and nontoxic in comparison with synthetic polymers. It's a new candidate for being substitute synthetic polymers owing to its biocompatible, renewable and biodegradable properties. The most abundant and inexpensive natural polysaccharide biopolymer starch is found in plant tissues and produced by...
Nowadays, detection of limb movements from electroencephalogram (EEG) signals is crucial issue to focus on. Many studies on the movement detection of the limbs such as arm, leg, wrist limbs exist, while there are few studies regarding finger movements. Our study aims to determine the best classified finger pairs using binary classification with highest accuracy among individual finger movements. In...
Electroconductive gels are widely used in biomedical applications for a proper transmission of produced signals to related body points of patients. During the transmission the biomedical gels play vital role in terms of relatively small signal loss and hence effective treatment. In some cases, disposable electrodes with self-gel attachments are used for quick application, however there are several...
PET imaging is increasingly used in determining functional tumor volumes for therapy response assessment and treatment planning. Accurate measurement of metabolically active tumors may improve optimal delivery of radiation treatment. However, volume measurement of small tumors (<2 cm) has been a much investigated subject due to Partial Volume Effect and limited resolution of the system. This research...
Reflective optical SpO2/Heartbeat sensors are very popular nowadays due to their ability to be used in different body regions that makes many different innovative designs possible. However, performance tests and evaluations are needed to obtain reliable and stable measurement results from these sensors. In this study, the performance of such a sensor, namely MAX30100 SpO2/Heartbeat sensor, has been...
In this study, the effect of the luminance level on the emotional evaluation was investigated using P300 waves observed in electroencephalography (EEG) records. EEG records of 31 helathy individuals were used in this study. The power graphs of records were examined and statistical analysis of the features obtained these power values was performed. With the findings, it was tried to find out how the...
HEVC which is the new image coding standard provides higher compression performance over the existing standards. In this study, compression of medical images is fulfilled with HEVC intra prediction method. The compressed images for storage or transmission purposes should not lose their required characteristics for the diagnosis after the recovery process. The recovered compressed images are evaluated...
Infertility is the inability pregnant in one year. The incidence of infertility is increasing day by day. Spermiogram (sperm test) is non-invasive and infertility is diagnosed with this test. The treatment is based on the result of the test. In this study, computer assisted sperm analysis (CASA) was performed on sperm images using image processing algorithms.
