Improved detection of microbubble signals using power M-mode Doppler.

UNLABELLED Background- Power motion-mode transcranial Doppler (TCD) (PMD) is a new, multigated technique that may simplify and enhance detection of embolus. We developed criteria for emboli detection using PMD. Then, we performed a blinded comparison of transcranial PMD with single-gate spectral TCD in TCD bubble study patients. METHODS Patients with right-to-left shunt as detected with stand...

Comparison between M-Mode and Doppler echocardiography in diagnosis

Introduction: Patent ductus arteriosus (PDA) is the persistence of a normal fetal structure between left pulmonary artery and descending aorta. Persistence of this fetal structure beyond 10 days of life is considered abnormal. In this study we compared M-Mode and Doppler echocardiography in diagnosis of PDA in children at Aliasghar Hospital in Zahedan and Children hospital in Bandar Abbas for...

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...

Robot control system using SMR signals detection

One of the important issues in designing a brain-computer interface system is to select the type of mental activity to be imagined. In some of these systems, mental activity varies with user intent and action that must be controlled by the brain-computer system, and in a number of other signals, the received signals contain the same activity-related mental activity that should be performed by t...

Validation of Carotid Duplex and Power M-mode Transcranial Doppler for Detection of Internal Carotid Artery Stenosis

Background – Carotid duplex ultrasound (CDU) is routinely used for detection of extracranial internal carotid artery (EICA) stenosis in stroke patients. Power M-mode transcranial Doppler (PMD-TCD) is a new technology designed for studying intracranial vessels. This prospective study was performed for validation of CDU versus digital subtraction cerebral angiography (DSA) and PMD-TCD versus CDU ...
