1. A medical object for arrangement in an object under examination, the medical object comprising:
an optical fiber configured to contact at least one light source optically;
multiple photoacoustic absorbers that are arranged in sections along a direction of longitudinal extension of the optical fiber, along a periphery of the optical fiber, or along the direction of longitudinal extension of the optical fiber and along the periphery of the optical fiber,
wherein the optical fiber comprises a sheathing, a portion of the sheathing being arranged between adjacent photoacoustic absorbers of the multiple photoacoustic absorbers,
wherein the multiple photoacoustic absorbers are configured to be arranged at least in part in the object under examination,
wherein the optical fiber is configured to conduct an excitation light emitted by the at least one light source to the multiple photoacoustic absorbers, and
wherein the multiple photoacoustic absorbers are configured to be excited by the excitation light for photoacoustic emission of ultrasound.
