1. An adaptive ultrasound detecting method comprising:

  • emitting an ultrasound beam along a scanning direction and receiving an echo value e(i) from a number I of sensing positions i along said scanning direction;

    comparing each said echo value e(i) to a detection threshold dt(i) corresponding to said sensing position (i);

    whereby, a detection occurs when said echo value e(i) is greater than said detection threshold dt(i);

    the improvement wherein at least one of said detection thresholds dt(i) is revaluated over time to cope for environment changes at sensing position (i) corresponding to said at least one of said detection thresholds dt(i).
