Ultrasonic Classification of Emboli

Quantification of ultrasound emboli signals in patients with cardiac and carotid disease.

BACKGROUND AND PURPOSE The use of Doppler ultrasound to detect arterial emboli has major implications for the classification and treatment of stroke. Experimental studies indicate that embolic materials produce different ultrasound signals, depending on their acoustic properties. To examine the possibility of characterizing emboli of different sources in the clinical setting, we compared the em...

TWELVE-MONTH TECHNICAL PROGRESS RETORT on RESEARCH ON DEEP SUBMERGENCE DIVING PHYSIOLOGY AND DECOMPRESSION TECH- NOLOGY UTILIZING SWINE: EVALUATION OF SWINE AS A HYPERBARIC ANALOG TO MAN AND DETECTION OF EMBOLI BY USE OF THE ULTRASONIC DOFPLER FLOWMETE*:

New ultrasonic radiation reduces cerebral emboli during extracorporeal circulation.

OBJECTIVE Cardiac surgery is associated with intraoperative cerebral emboli, which can result in postoperative neurological complications. A new ultrasonic transducer (EmBlocker) can be positioned on the ascending aorta and activation of the EmBlocker is expected to divert emboli to the descending aorta, thereby decreasing emboli in the cerebral arteries. In this preliminary animal study, safet...

ارتباط شدت آمبولی ریه در سی تی آنژیوگرافی با یافته‌های ECG در بیماران مبتلا به آمبولی حاد ریه

   Background & Aims: The most common diagnostic modality for pulmonary emboli is CT angiography (CTA). Because of the availability and inexpensiveness, taking an electrocardiogram (ECG) is the first step in patients suspicious to pulmonary emboli. However, ECG does not provide any sensitive or specific manifestations for diagnosis of pulmonary emboli. We aim to evaluate the correlation between...

Uncertainty Measurement for Ultrasonic Sensor Fusion Using Generalized Aggregated Uncertainty Measure 1

In this paper, target differentiation based on pattern of data which are obtained by a set of two ultrasonic sensors is considered. A neural network based target classifier is applied to these data to categorize the data of each sensor. Then the results are fused together by Dempster–Shafer theory (DST) and Dezert–Smarandache theory (DSmT) to make final decision. The Generalized Aggregated Unce...
