DEVICE AND METHOD FOR ANALYZING OPTOACOUSTIC DATA, OPTOACOUSTIC SYSTEM AND COMPUTER PROGRAM

摘要

The invention relates to a device and a method for analyzing optoacoustic data, an optoacoustic system for generating and analyzing optoacoustic data and a computer program. The device for analyzing optoacoustic data according to a first aspect of the invention comprises a data processing unit configured to determine a spatial distribution of at least one first value, which relates to concentration of collagen in a tissue comprising at least one of a muscle tissue, connective tissue, organ, tendon and/or pathogenic (fibrotic) tissue, based on optoacoustic data relating to acoustic waves generated in the tissuein response to irradiating the tissue with time-varying electromagnetic radiation at two or more different irradiation wavelengths, derive at least one second value from the spatial distribution of the at least one first value, the at least one second value corresponding to or being derived from at least one distribution parameter characterizing the spatial distribution of the at least one first value within a region of interest of the spatial distribution of the at least one first value, and provide the at least one second value and/or diagnostic information derived from the at least one second value for further use, in particular for displaying the at least one second value and/or diagnostic information on a display unit.
