Detection of Doppler Microembolic Signals Using High Order Statistics

Robust detection of the smallest circulating cerebral microemboli is an efficient way of preventing strokes, which is second cause of mortality worldwide. Transcranial Doppler ultrasound is widely considered the most convenient system for the detection of microemboli. The most common standard detection is achieved through the Doppler energy signal and depends on an empirically set constant thre...

Automated intraoperative detection of Doppler microembolic signals using the bigate approach.

BACKGROUND AND PURPOSE We undertook this study to evaluate the performance of an automated detection software in the detection of Doppler microembolic signals (MES) during cardiac surgery. METHODS Intraoperative monitoring was performed over two spatially separated vessel segments of each middle cerebral artery in 18 patients undergoing coronary artery bypass surgery (n= 16) or cardiac valve ...

Doppler Microembolic Signals in Behcet\'s Disease with Nervous System Involvement

Background: Behçet’s disease (BD) is a multisystemic inflammatory vasculitis of unknown etiology, and vasculitis being its major pathological feature. Objectives: We studied the prevalence of microembolic signals (MES) in patients with diagnosis Behçet's disease. We also tried to determine the frequency of MES in BD patients with or without neurological involvement. Mater...

Automated Detection of Fetal Movements in Doppler Ultrasound Signals versus Maternal Perception

Analysis of movement activity is important since it enables detection of nonreactive fetal heart rate recordings. The aim of the study was to develop an algorithm for automated detection of the fetal movement activity (actogram), based on analysis of the Doppler ultrasound signal, and to evaluate a reliability of the actogram as a source of information about the fetal movements. Bandpass filter...

Feature extraction from Doppler ultrasound signals for automated diagnostic systems

This paper presented the assessment of feature extraction methods used in automated diagnosis of arterial diseases. Since classification is more accurate when the pattern is simplified through representation by important features, feature extraction and selection play an important role in classifying systems such as neural networks. Different feature extraction methods were used to obtain featu...
