Table 1.
Accuracy (95%) in °C for estimating temperature at 44°C in configurations tested with simulation, assuming normal distribution with computed standard deviation and slope (dCBE/dT) of CBE as function of temperature. Naq/Nlip denotes the ratio of aqueous to lipid scatterers assumed. Values marked baseline were used while varying other parameters, e.g., simulations for varying region size employed a 2:1 aqueous-to-lipid ratio and SNR of 19dB.
