Claim 8:
9. A program element comprising instructions, which causes the integrity detection system according to claim 1, when executed on a processor of the signal processing unit thereof, to execute a method for detecting an integrity status of an acoustic coupling between the ultrasound transducer and the wall of the vessel, the method comprising:
emitting, by the first ultrasound emitter, the first ultrasound test signal, the first ultrasound emitter being attached to the wall of the vessel;
receiving, by the at least one ultrasound receiver, the first ultrasound test signal, the at least one ultrasound receiver being attached to the wall of the vessel, and transmitting the received first ultrasound test signal to the signal processing unit;
detecting, by the signal processing unit, the first time of flight of the received first ultrasound test signal; and
determining, by the signal processing unit, that the acoustic coupling of the first ultrasound emitter and the first ultrasound receiver to the wall of the vessel is intact if the detected first time of flight corresponds to the length of the path in the wall of the vessel from the first ultrasound emitter to the at least one ultrasound receiver.
