FIELD: medicine.
SUBSTANCE: ultrasonic system for gas pocket detection comprises an ultrasound probe, a unit for reception of the second harmonic component of the ultrasonic echo for each depth from a plurality of depths along each scanning line from a plurality of scanning lines; and a unit for detection of a change in the central frequency of the second harmonic component in depth. The method for gas pocket detection is implemented by means of an ultrasonic system.
EFFECT: application of the inventions allows to increase the accuracy of gas pocket detection.
