Abstract
A method and apparatus for non-destructively or non-invasively measuring a temperature change in the inside of a subject, in particular a living subject, identify the temperature change in a region of interest during the course of producing ultrasound images of the region by determining the change of the acoustic impedance of the region of interest, and allocating a temperature change to the impedance change. An installation for treating a living subject with heating radiation which employs the above method and apparatus for measuring the temperature change of a region of treatment, is also disclosed.
