Abstract

A medical object for arrangement in an object under examination includes an optical fiber. The optical fiber is configured to contact at least one light source optically. The medical object further includes multiple photoacoustic absorbers that are arranged in sections along a direction of longitudinal extension of the optical fiber and/or along a periphery of the medical object. The multiple photoacoustic absorbers are configured to be arranged at least in part in the object under examination. The optical fiber is configured to conduct an excitation light emitted by the at least one light source to the multiple photoacoustic absorbers. The multiple photoacoustic absorbers are configured to be excited by the excitation light for the photoacoustic emission of ultrasound.
