) (Left) Simulated temperatures based on a finite-element simulation of heating from a 65°C source in the
center and a fixed 37°C surrounding temperature. (Right) Temperature images estimated with CBE from simulated images for a homogeneous
scatterer distribution over the heated region with an SNR of 24dB. The mean estimation error for was 0.4 ± 0.2°C. (From Basu, D.,
