Abstract

See full text

Temperature inside a tissue volume is noninvasively determined on the basis of its known relationship with the velocity of ultrasound inside the volume. The velocity of ultrasound between two field points inside the volume of interest is calculated from measurements of differences in transit times of sound beams scattered in substantially opposite directions at these field points.
