Table 2.
For each of the cycle lengths at which the simulated cylindrical target was driven, the resulting images were segmented and the centroid positions plotted against frame number were fitted to a sinusoidal curve. The fitting parameters from the MATLAB sinusoidal curve are presented here. The target was driven with a 20 mm amplitude at 3–9 s per breath
