Abstract

A medical system comprises a measurement device. The measurement device comprises an imaging scanner, such as an ultrasound scanner, configured to generate an image of a first region of interest, and an optical scanner comprising at least one light emitter configured to emit light into a second region of interest and at least one light detector configured to detect the light that has interacted with a tissue in the second region of interest, to generate optical measurement data. The at least one light emitter and the at least one light detector and the imaging scanner are aligned with each other 10 at least during the measurements, so that the first region of interest overlaps the second region of interest, and the first region of interest is registered with the second region of interest.
