Abstract
Se describe un procedimiento para la representacion gráfica selectiva y/o evaluacion del espectro Doppler de objetos limitadamente resistentes a la intensidad sonica, por ejemplo organos biologicos y tejidos, mediante un procedimiento ultrasonico, en donde un material es introducido en el área de examinacion que va a ser acusticamente irradiada, se producen oscilaciones no lineales en elárea de examinacion mediante ondas ultrasonicas, y la señal es evaluada por un convertidor ultrasonico. También, se describe un circuito para llevar a cabo el procedimiento anterior.
