[0194] Carry out 2D (two-dimensional) or 3D (three-dimensional) measurements, and more advantageously, especially in 1D (one-dimensional), in other words on one ultrasound line: practically, 2D or 3D measurements are not necessary, so back Data processing of scattered ultrasound signals is faster,

[0195] Taking into account the sensitivity and frequency of the ultrasonic transducer, in other words for a specific ultrasonic transducer, the sensitivity and frequency of the specific ultrasonic transducer provided by the manufacturer, in order to adapt the Signals transmitted to the laws of statistics;

Abstract

The invention relates to a method (100) for determining in real time that a target biological tissue is opposite an ultrasound transducer, the method (100) comprising the steps of: transmitting (101) an ultrasound signal into the biological tissue via the ultrasound transducer ; said ultrasound transducer receives (102) said transmitted ultrasound signal which has been backscattered by said biological tissue; calculates (103) at least two instantaneous parameters E, LIN, ATT of said backscattered ultrasound signal; calculating (104) a predictor value P of the presence of an acoustic marker of the target biological tissue, said predictor value P being calculated via a statistical law using said at least two calculated time parameters E, LIN, ATT; estimating (105) the The probability that the target biological tissue is located opposite the ultrasound transducer, the estimation (105) depends on the calculated predicted value P and / or on the instantaneous parameters E, LIN, ATT based on the two calculations at least one intensity condition for .

Description

technical field [0001] The present invention relates to a method for determining in real time the likelihood that a target biological tissue is located opposite an ultrasound transducer. For example, the ultrasound transducer may belong to a so-called "blind" or "partially blind" measuring probe. "Blind" means that the measurement device to which the measurement probe is connected does not have a live imaging mode. Furthermore, "partially blind" means that the imaging mode of the measurement device is limited to one-dimensional (1D) ultrasound lines of the A-SCAN type optionally associated with the M-type mode. Background technique [0002] Conventionally, in order to measure a quantitative or qualitative parameter of a biological tissue, a measurement probe is placed opposite said tissue. [0003] When it is desired to position a blind or partially blind measuring probe opposite the target biological tissue, this positioning can be carried out in two ways: [0004] Posit...
