Abstract
PROCEDIMIENTO PARA SATISFACER LOS DIFERENTES REQUISITOS DE ANCHURA DE BANDA DE LOS SISTEMAS DUPLEX EN UN SISTEMA ULTRASONICO DE FORMACION DE IMAGEN. UN CONDUCTO DE TRANSDUCTOR COMUN (11), RECIBE IMPULSOS DE ULTRASONIDO. DE LA VARIACION DE LA FRECUENCIA DE LOS ECOS PUEDE OBTENERSE LA VELOCIDAD DE CIRCULACION DE LA SANGRE. SE EXCITA EL CONJUNTO DE TRANSDUCTOR (11) PARA HACER VARIAR LA ANCHURA DE BANDA DE LOS IMPULSOS ULTRASONOROS EMITIDOS. EN ESTA VARIACION SE GENERAL UN IMPULSO DE ULTRASONIDO CON UNA BANDA ANCHA, MODALIDAD DE EXPLORACION B, O ESTRECHA, MODALIDAD DOPPLER, APLICANDO UN SOLO IMPULSO O IMPULSOS MULTIPLES, RESPECTIVAMENTE, A CADA ELEMENTO DEL TRANSDUCTOR ELEGIDO. DICHOS IMPULSOS MULTIPLES TIENEN UNA FRECUENCIA SEMEJANTE A LA FRECUENCIA CENTRAL DE LA EMISION ULTRASONORA.
