Semi-quantitative analysis of 3D perfusion data sets in eight healthy volunteers allowed for calculation of the left-to-right perfusion ratio (ratio 0.9), which was confirmed by phase-contrast flow measurements [68].
Calculations of the left ventricular outflow tract (LVOT) area are typically based on the assumption that the LVOT is circular.
For, a direct calculation of the upper left derivative of along the solutions of system (1.5) leads to (3.28).
The update of each atom involves the calculation of the largest left singular value of a matrix Y k of approximate size (dtimes frac {SN}{K}) for several iterations.
Since we acquired seven MR slices for the whole mouse heart, imperfect definition of the valve plane could have had an impact on the final calculation of the corresponding left ventricular volumes as well as on the LVEF.
The end, epi- and endocardial contours of the entire LV slices were manually traced at end-diastolic (EDV) and end-systolic (ESV) phases for calculation of the corresponding left ventricular volumes, as well as the LVEF.
The same calculation applies to the left of arm 5 (Chr5L), but with 5 LOH events for a probability of 0.0128.
Figure 6 shows the results of the calculations: in the left, in the central and in the right panels we have reported the solution obtained with the ADER-Prim, with the ADER-Cons and with the ADER-Char scheme, respectively, while the top and the bottom panels correspond to two different times during the evolution, namely (t=2.0) and (t=2.5).
Calculation of the coordinates of the right and left pupil border peaks, (x right, y right) and (x left, y left), are followed by the calculation of the center and the diameter of the pupil by Eq. (1), (1) (x center, y center, D ) = (x right + x left 2, y right + y left 2, x right − x left ).
