Procedure for measuring at least one property of a biological tissue (12) that includes the steps: - placing (1) an ultrasonic transducer (12) next to said biological tissue (16) to be measured； - generating (21) at least one ultrasonic signal in said biological tissue (16)； - acquiring (22) at least one ultrasonic signal reflected by said biological tissue (16)； - determining (3) at least one parameter of said biological tissue (16) by means of said acquisition (22) of at least said ultrasonic signal reflected by said biological tissue (16), said parameter being at least said representative of said biological tissue (16) ； said procedure being characterized in that it also includes the steps: - comparing (4) at least said parameter of said biological tissue (16) with at least one reference parameter of a target biological tissue to validate the hypothesis of presence of said target biological tissue next to said ultrasonic transducer； said comparison (4) consisting in comparing a value of at least said determined parameter with a value of at least said reference parameter, - determining (5) at least one property of said biological tissue (16) based on the result of said step of comparison (4), said step of determining (5) of at least said property being performed only if the absolute value of the difference between said value of at least said determined parameter and said value of at least said reference parameter is less than one determined threshold value.Procedimiento para la medición de al menos una propiedad de un tejido biológico (12) que incluye las etapas: - colocar (1) un transductor ultrasonoro (12) junto a dicho tejido biológico (16) que se tiene que medir； - generar (21) al menos una señal ultrasonora en dicho tejido biológico (16)； - adquirir (22) al menos una señal ultrasonora reflejada por dicho tejido biológico (16)； - determinar (3) al menos un parámetro de dicho tejido biológico (16) mediante dicha adquisición (22) de al menos dicha señal ultrason
