[Start of:'Phase encoding'1 Reply] Category: General Phase encoding Hello, Could someone explain me simply the principle of phase encoding ? I don't understand the principle of applying higher gradient at each step. Thanks ! View the whole thread Reply to this thread(login or register ...
From the definition of the generalized function Eq. (296), TIE retrieves the conditional frequency moment of the WDF as the phase gradient, so the reconstructed phase in the image plane is not coincident with the true phase of the object in general [expect for the case of perfect imaging,...
(corresponding to ϕ = 236.3° and 303.7°) for the LCP incidence according to the phased-array antenna theory, while the constant phase gradient along y-direction will deflect the scattering wave into the plane towards the negative y-direction with an angle of 33.5° deviated from x-z...
To represent the typical case of training, we evaluate the gradient on random choices of the circuit parameters via a numerical finite-difference. Without loss of generality, we consider the gradient over the first variableγ1and denote it as\({\partial }_{1}{{{\mathcal{C}}}\)28,29. ...
predicts to a great accuracy the mean maximum data rate. The authors have further used maximumtransmission data ratesand RSS values to predict channel throughput within a constantly changing environment. The throughput prediction results though not very accurate, do follow the general gradient of the ...
and plasmids encoding the ENO1 gene. In vivo, specific inhibitor interventions and AAV-ENO1 delivery were applied to explore the same. In order to analyze cell behaviors, including cell proliferation, angiogenesis, and adhesion, assays were used; seahorse analysis was employed to measure mitochondria...
Abstract Aiming at the problems of inaccuracy in detecting the α phase contour of TB6 titanium alloy. By combining computer vision technology with human vision mechanisms, the spatial characteristics of the α phase can be simulated to obtain the contour accurately. Therefore, an algorithm for α...
Here, the definition of backpropagation is adopted in machine learning [28]. Our optimization variables are pixel-wise 2D phase distributions (105-106 degrees of freedom), so calculating the finite difference gradient would be extremely time-consuming. However, algorithmic differentiation provides a ...
During the training phase, the weights associated with each epoch can assume a range of real values based on the gradient. However, in order to compute and evaluate the Forman–Ricci curvature for each edge, it is necessary for the weights to be positive. To address this requirement, we emp...
2. The method as set forth in claim 1 wherein the phase encoding step includes phase encoding along at least two gradient axes such that the voxel is divided into a two dimensional array of subvoxels. 3. The method as set forth in claim 2 wherein the displaying step includes displaying ...
