METHOD AND DEVICE FOR ULTRASOUND-BASED RECOGNISING OF MOVABLE ANATOMICAL STRUCTURES

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medical equipment, namely to movable anatomical structure recognisers, particularly for detecting foetal cardiac contractions. A method of recognising involves the stages of obtaining ultrasonic data comprising a Doppler shift of at least one anatomical structure, dividing the ultrasonic data by a number of time gaps, drawing a feature vector for each time gap, classifying each time gap with the use of the Doppler shift by recognising with the use of a pattern recognition modulus of at least one anatomical structure by means of the classification of each time gap. The substance is implemented by a recognition system comprising a microprocessor and integrated into a foetus monitor comprising an ultrasonic system with the use of an ultrasonic converter.;EFFECT: using invention enables reducing risks of fault recognition of the movable anatomical structures inside a subject.;13 cl, 5 dwg
