DT in group 1 was significantly shorter (p < 0.01) in the acute than in the subacute phase (104 ± 46 vs. 204 ± 42 ms). These results indicate that patients with hemodynamically significant right ventricular infarction have a characteristic Doppler echocardiographic right ventricular filling ...
-Phase quadrature, or quadrature detection is commonly used signal processing technique for bidirectional Doppler Continuous wave Doppler advantages -Greatest advantage of continuous wave Doppler is its ability to accurately measure high velocities Continuous wave Doppler disadvantages The exact location of ...
The phase shift, δφ, of a single emission line as a function of the optical path difference, 2Δd, can be written as: δφ=4πΔdσ(v/c) (3) where σ is the non-Doppler shifted wavenumber of the emission line, v is the Doppler velocity and c is the speed of light. ...
(10.47)Δϕ=4πk0VDn(k0)T cosθ whereTis the A-scan period as defined earlier. That means the phase shift between consecutive A-scans is stationary. Thus, the Doppler velocity can be retrieved by measuring the phase variation between consecutive A-scans as ...
[41], a diastolic velocity <20 cm/s is predictive of poor outcome. In a prospective paediatric study including 36 children with moderate or severe TBI, diastolic velocity <25 cm/s and PI >1.31 on TCD at admission but after the first resuscitation phase (correction of low blood pressure, ...
TB1 corresponds to the raw data of B-Fresh1, TB2 corresponds to the raw data of B-Fresh2, and TB3 corresponds to the raw data of B-Fresh3. For better readability, we will refer to dynamic synchrotron-based-phase contrast X-ray microtomography simply as dynamic microtomography henceforth. ...
at least in part, of the relatively longer experimental sessions for these participants (i.e., the experimenters would try as long as possible to find a stable signal, and thus participants without a signal spent more time on average in the pre-task phase of the study than did the other ...
