Abstract
1. Способ просветного акустического зондирования легких, заключающийся в излучении в полость рта кодированного акустического сигнала, приеме отклика акустическим датчиком, установленным на поверхности грудной клетки, построении графика взаимно-корреляционной функции излученного и принятого сигналов, выделении и определении по графику величины задержки максимума взаимно-корреляционной функции от момента излучения и последующем картировании легких по величине задержки, отличающийся тем, что в полость рта излучают широкополосный кодированный акустический сигнал с нижней частотой 80 Гц и шириной полосы частот не менее 200 Гц, прием отклика производят акустическим датчиком вибраций, построение графика осуществляют по модулю взаимно-корреляционной функции излученного и принятого сигналов, выделяют по полученному графику два максимума, а задержку времени определяют как разницу между ними. ! 2. Способ по п.1, отличающийся тем, что в качестве кодированного сигнала используют линейно-частотно-модулированный или фазоманипулированный сигналы. 1. A method of translucent acoustic sounding of the lungs, which consists in emitting an encoded acoustic signal into the oral cavity, receiving a response with an acoustic sensor mounted on the surface of the chest, plotting the cross-correlation function of the emitted and received signals, isolating and determining from the graph the delay value of the maximum correlation function from the moment of radiation and subsequent mapping of the lungs in terms of delay, characterized in that a broadband code is emitted into the oral cavity an acoustic signal with a lower frequency of 80 Hz and a bandwidth of at least 200 Hz, the response is received by an acoustic vibration sensor, the graph is constructed modulo the cross-correlation function of the emitted and received signals, two maxima are extracted from the obtained graph, and the time delay is determined as difference between them. ! 2. The method according to claim 1, characterized in that the linear-frequency-modulated or phase-shifted signals are used as the encoded signal.
