We propose a method for measuring the temperature distribution in space using ultrasound computerized tomography (CT). We verified by simulations and experiments that reconstruction of the air temperature distribution is possible using a time of flight profile. Good experimental results were obtained in the reconstruction of a point heat source 30° hotter than room temperature in an area of 100 mm × 100 mm using ultrasound with a frequency of 40 kHz.
