Abstract

Un dispositivo de ecografía portátil (109) para obtener imágenes de forma no invasiva de una estructura subcutánea seleccionada, que comprende: (a) una carcasa (110); y (b) una pluralidad de conjuntos (300A) de elementos transductores (300). Cada conjunto (300A) está dispuesto en paralelo y cada elemento transductor (300) comprende un transductor transmisor (705) y un transductor receptor (707), ubicado dentro de la carcasa (110) para transmitir continuamente energía de ecografía en un rango de frecuencia predeterminado hacia una cuerpo (100) de un sujeto y recibir continuamente señales de eco en un rango de frecuencia predeterminado desde el cuerpo (100) del sujeto. La pluralidad de conjuntos paralelos (300A) permite obtener imágenes de la estructura subcutánea (101, 101A) en múltiples planos transversales y laterales. El dispositivo de ecografía (109) incluye además (c) un controlador (250) para operar la pluralidad de conjuntos (300A) de elementos transductores (300) y comunicable con un procesador (350) para procesar señales de eco recibidas de la pluralidad de conjuntos (300A) de elementos transductores (300); y (d) una pantalla (104) para mostrar una imagen interpretable (104A, 104B) de dicha estructura subcutánea (101, 101A) producida por el procesador (350).
