Method and apparatus for the non-invasive determination of the temperature at with a radiation, in particular laser radiation treated biological tissue

摘要

A method and a device for the non-invasive temperature determination on with a therapeutic radiation, in particular laser radiation, treated biological tissue, in particular on the fundus oculi, in which during the respective irradiation time in substantially the same time intervals, additional radiation pulses of a low pulse duration and low energy to the treated biological tissue, wherein the resulting tissue expansions and / or - contractions by means of pressure measurement or optical measurement can be detected and from the measurement signals the absolute temperature values are determined and, if appropriate, the therapeutic radiation is controlled as a function thereof.
