Abstract

Se coloca una sonda ultrasonica en la cabeza de un paciente, y se utiliza para generar un pulso ultrasonico que se propaga por el craneo y cerebro del paciente, y se refleja del craneo y tejido blando en una trayectoria perpendicular a la sonda ultrasonica. Las senales reflejadas son recibidas por la sonda ultrasonica, y luego se procesan de forma conocida para generar una senal ecoencefalografica (Eco EG), que se grafica como funcion de amplitud contra distancia. Luego se selecciona una porcion de la senal Eco EG, y la senal Eco EG se integra sobre la porcion seleccionada para generar una senal ecopulsografica (EPG). Tambien se genera una senal electrocardiografica (ECG) de forma conocida. Utilizando la senal ECG como referencia, se utiliza la senal EPG para proporcionar informacion acerca del estado fisiologico del tejido a una profundidad desde la sonda ultrasonica correspondiente a la porcion seleccionada de la senal Eco EG. Ademas, la sonda ultrasonica es preferiblemente una sonda con una superficie transmisora y receptora de forma concava.
