摘要 |
The invention relates to a method (100) for determining, in real time, the probability that target biological tissue is opposite an ultrasonic transducer, said method (100) comprising the following steps: transmitting (101), via an ultrasonic transducer, an ultrasonic signal into biological tissue; said ultrasonic transducer receiving (102) said transmitted ultrasonic signal which has been backscattered by said biological tissue; calculating (103) at least two instantaneous parameters E, LIN, ATT of said backscattered ultrasonic signal; calculating (104) a predictive value P of the presence of an acoustic signature of target biological tissue, said predictive value P being calculated via a statistical law using said at least two calculated instantaneous parameters E, LIN, ATT; estimating (105) the probability that said target biological tissue is opposite said ultrasonic transducer, said estimation (105) depending on said calculated predictive value P and/or on at least one strength condition based on at least one of said two calculated instantaneous parameters E, LIN, ATT. |
