Physical density maps of ex vivo bovine muscle in water (ρ = 1 g/cm3) at the lowest (22 °C, A) and highest (45.5 °C, B) temperatures. Increase in temperature resulted in a decrease in physical density. The area of high constant physical density (yellow) corresponds to optical fiber temperature probes placed to obtain ground truth temperature measurements.
