A pectoral muscle usually resembles a salient dense region, which is roughly triangular shape, in mediolateral oblique (MLO) position mammography. Similarly, masses usually appear to be salient dense in mammograms. Therefore, first of all, most computer-aided detection (CAD) systems remove the pectoral muscle region in order to reduce the number of false positives. In this study, a method is proposed...
Obsessive Compulsive Disorder (OCD) is a neuropsychiatrie disorder that usually negatively affects feelings and thoughts of adolescent adversely. Studies of OCD with imaging methods have found intense mental activity in the frontal region. In this study, relative power values are calculated for the channels representing the frontal regions. These values were compared with the data values of the data...
In this study, the power spectral density of simulated data which contain neuromuscular diseases and normal motor unit (i.e. control group) scenarios was calculated using Welch's method. Furthermore, the effect of Welch's method on differential diagnosis was investigated. Data were recorded both near innervation zone which is the area that motor unit action potential occurs and near tendon. Multi-layer...
Chronic Obstructive Pulmonary Disease (COPD) is a persistent respiratory disease usually caused by toxic gases. The diagnosis is made by a specialist doctor on a report taken by a specialist technician using a spirometer. Diagnostic steps can only be carried out in hospital environment in the presence of a qualified technician. The diagnostic process is so troublesome that it leads to alternative...
In this study, it was implemented a wristband design which provides distance measurements to assist blind people. The obstacles were detected by the help of ultrasonic sensors connected to an Arduino microcontroller board. A design that can be adapted to different usage areas (indoor or outdoor) and various stimulus types (vibration only, sound only, both together), is produced, which concerns user...
Today, with the improvement of socioeconomic conditions, consumption of ready-to-eat foods increased and a more non-mobile lifestyle became widespread. Thus, the incidence of a number of metabolic problems together has begun to increase. These problems arise in the form of bodily changes, deterioration of glucose tolerance, disorders of fat metabolism and blood pressure elevation. It is called the...
Cardiovascular disease is one of today's major health problems. These diseases are the result of constriction or blockage of coronary vessels feeding heart. Diagnosis of Cardiovascular contraction is determined visually by physicians with angio imaging method. Visually defined vascular diseases may give subjective results. Vessel constrictions in angiograms are automatically determined by vascular...
In this study, the mechanical model of the electronically controlled knee prosthesis is developed, forward and inverse kinematic analyses are performed, and trajectory tracking for joint space is obtained, respectively. The analyses were carried out considering a cycle of gait walking at a constant speed. Thus, position, velocity and acceleration data of the prosthesis of joint space required for...
Stroke has become a common disease, often leading to motor dysfunction and causing disability. Lower-limb robotic rehabilitation can help patients to carry out reasonable and effective training to improve the motor learning. The developments of lower-limb rehabilitation robots are investigated in this review and also clinic requirements have been discussed in recent years. Consequently, the future...
When pathologists analyze the cytopathological assessment process, they firstly find the optimum focused region by moving the microscope table along the Z axis. Auto-focusing provides a better and more effective imaging by reducing the personality dependence on the microscope system. Various studies have been carried out in the literature to determine the optimum auto-focus function. The aim of the...
In this paper, the training standards established for the planned certified training program on the training of personnel engaged in the test, control and calibration of medical devices are presented. Certificates to be obtained after this training will be registered by the Ministry of Health and become a working document. According to the regulation published by Turkish Medicines and Medical Devices...
There are fragments in the heart can attributed to innate or diseases that can be seen during the lifetime. As a common term “Arrhythmia” is the name of diseases that anomaly rhythmic work of the heart that result from the various disorders. Electrocardiography is frequently still using by clinics to detect these rhythm disorders. The system base on computers is utilized to minimize interference failures...
In recent days biometric features are frequently used in the field of personal identification and authentication. Retinal vessels are important biometric features in this manner. It is suggested a personal identification system used retinal blood vessel topology in this paper. For this purpose, characteristic feature matrix that is extracted by using topological features. The position of these feature...
This paper is written with the aim of presenting the studies about building standards-based and auditable measurement services for medical device test controls and calibrations in Turkey. In particular, the activities of biomedical metrology service providers about to train specialist personnel and to establish sectoral awareness in this field have been mentioned. Turkish Medicines and Medical Devices...
Reaction time that is the period between the emerging of the target stimulus and the subject's motor response is an important and informative tool in the study of cognitive ability in psychology and other disciplines. In this study we proposed to evaluate attention level of students before and after an exam via a designed stimulus system. The study conducted on 30 individuals that are studying at...
Epilepsy is characterized by temporary and unexpected electrical deterioration in brain. EEG is preferred in diagnosis. There are many studies in the literature on EEG signals to differentiate between groups in epileptic and non-epileptic individuals. In this study, EEG signals were examined for predicting seizures for the three pre-, during, and post-seizures. The EEG was filtered by Singular Spectrum...
The purpose of this study was to analyze the electromyography (EMG) signals of the Quadratus Lumborum (QL) muscle activity on leg length discrepancy (LLD) and pelvic asymmetry. So we investigated whether pelvic asymmetry might cause injuries in lumbar spine and lower extremity. This was a randomized control experiment, total 50 (25 males and 25 females) datas were analyzed. All participants were right...
In this study, a mobile based project depended on client-server communication has developed for the early diagnosis of eye diseases. It is a disadvantage that the technical devices used in the diagnosis of eye diseases are expensive and not portable. For this reason, a mobile based system is proposed in order to make eye examinations more practical and cheap in the study. The estimated pathological...
The width, thickness and the length of the organs are frequently used for volume calculations in radiology. Thus, radiologists can determine the approximate volumes of the regions rapidly. In this work Butterworth based volume calculation method is proposed for the injured kidneys. The outputs of the proposed method are compared with two different traditional methods. The results are given as root...
