Elevation of intracranial pressure (ICP) may occur in many diseases, and therefore the ability to measure it noninvasively would be useful. Flow velocity signals from transcranial Doppler (TCD) have been used estimate ICP; however, relative accuracy these methods is unclear. This study aimed compare four previously described TCD-based with directly measured ICP a prospective cohort traumatic brain-injured patients. Noninvasive (nICP) was obtained using following methods: 1) mathematical...
BACKGROUND: In traumatic brain injury (TBI), swelling may disturb the potentially uniform pressure distribution in brain, producing sustained intercompartmental gradients which associate with midline shift. The presence of is often neglected since bilateral invasive intracranial (ICP) monitoring not usually considered because risks and high costs. We evaluated interhemispheric using transcranial Doppler (TCD) as means for noninvasive ICP (nICP) TBI patients presenting shift.METHODS: From a...
In various pathologies, such as hemorrhagic stroke or traumatic brain injury, intracranial pressure (ICP) can rise to the point of causing neurological damage and should consequently be monitored.The invasiveness current ICP monitoring procedures, however, limits patient pool.Having a non-invasive screening tool for detecting hypertension would therefore high value.In this work, we developed binary classifier determine if is above clinical cutoff value 20 mmHg.Arterial blood (ABP) cerebral...
One of the reasons which impede applications ultrasonic beam deflection flowmeters is their calibration that usually needs to be performed across whole range measured flow rates. In this paper we have aimed show given directivity pattern transducers, one can design a flowmeter with just transmitting and receiving transducer reduce process such device single measurement. Moreover, how optimize parameters transmitter-receiver setup in order maximize measurement accuracy. It leads us simple...
This article describes design of a new multichannel acquisition system with photomultiplier tubes (PMTs). The allows mean current measurement and photon counting for 2 PMT coincident operation. In order to obtain very high dynamic range, signal from the is sampled by 14 bit resolution ADC analyzed speed window discriminators constant fraction (CFD). Output data processed in FPGA transmitted embedded computer. has been developed astrophysical energy physics research.
